In their words

What specifiers and builders say.

Heritage architects, mechanical contractors, and homeowners. The brief looks different from every angle - what stays the same is the kind of partner Accumen® turns out to be.

The columns you made for us were a work of art - a perfect fit. Thank you.

Quentin

Column purchase

Thanks for the columns. They're now installed and painted and look a million dollars. Visitors are swooning at their beauty - and there's been a little hugging too.

Paul

Column purchase

We're now in and settled - it's been a good project. The corbels, window cills and eyebrows Accumen® made for us set the place off and have drawn excellent comments. Thanks very much for your help.

The project demanded an efficient means of restoring the Quay Building façade - Accumen® proved their expertise and were a valuable team to have alongside.

George Gregory

Cheshire Architects · Quay Building

A note to thank you for the work you did on the 3-D sign for us - it worked out really well. You guys did an excellent job, in a pretty quick turnaround. When we need anything similar again, I'll be in touch directly for sure.

Darryl

3D signage

These bands are by far the highest quality I have ever used. When I get the go-ahead from my insurance company to rebuild my house, I'll be using your bands on it.

01 / Division · Accumen® Mouldings

Architectural detail that defines the building.

Columns, cornices, parapets, quoins, chimneys, fence caps, letterboxes, and fully custom profiles, precision-manufactured since 1991 for heritage restorations, high-end residential, and commercial façades across New Zealand and beyond.

3 Proprietary systems

∞ Custom capability

35+ Years perfecting

Old Choral Hall reinstatement by Accumen® - classical façade with columns and pediment — Old Choral Hall Reinstatement by Accumen®

Accumen® designs and manufactures premium lightweight mouldings that bring timeless architectural detail to any home.

From classic heritage profiles to clean modern lines, our mouldings replicate the beauty of traditional plaster and stone - without the weight or complexity.

Crafted in New Zealand for durability and easy installation, they're ideal for restorations or new builds where style, performance, and precision matter.

Why Choose Accumen®?

35+ years of NZ manufacturing - proudly New Zealand made since 1991, with the country's longest specialist track record for architectural mouldings.
Three proprietary systems - DecraShape®, fourPLUS®, and ShapeCrete® - so we can spec the right material for the right job, from heritage replication to high-traffic commercial.
Custom-make capability - thousands of stock profiles, and we manufacture to drawing for anything outside the catalogue.
Lightweight + fast install - engineered to handle and fix like a normal moulding, with the look of solid plaster or stone.
One supplier, one delivery - columns, cornices, quoins, dentils, bands, letterboxes and fence caps shipped from a single Penrose-based factory.

Manufacturing Systems

Three systems. One standard.

Every Accumen® moulding is manufactured using one of our three proprietary systems - DecraShape® for the everyday standard (92 kg load test), fourPLUS® where impact-proof and weight-conscious historic work is the brief, and ShapeCrete® where solid lightweight concrete is the right answer. Chosen according to scale, profile complexity, exposure, and install method. Your specifier or quote will recommend the right one for your project.

DecraShape^®

Our lightweight expanded-polymer system. Ideal for ornate profiles, curved work, and installations where structural weight is a constraint. Finished with KickIt® plaster.

Lightweight · Ornate · Curved work

fourPLUS^®

Four-layer reinforced composite system. Exterior-grade durability for façade-scale mouldings, long cornice runs, and coastal exposure projects.

Exterior · Coastal · Large spans

ShapeCrete^®

Cast-concrete finish system for heritage-stone replication, heavy-duty applications, and projects where a genuine masonry weight and feel is specified.

Heritage · Masonry feel · Heavy duty

Engineered to Last

The detail is the point.

01, Weight

Heritage presence without the weight penalty.

A traditionally-cast stone cornice at the scale we regularly produce would weigh several hundred kilograms per linear metre, impractical for most builds and hostile to modern wall systems. Our DecraShape® and fourPLUS® systems deliver the same visual presence at a fraction of the structural load.

Which means columns that drop into a residential build without re-engineering the portico, and cornice runs that can wrap a commercial façade without fixing penalties.

02, Finish

Finishes that hold up, here.

KickIt® plaster finish gives you a workable, paint-ready surface (apply a flexible sealer first) that sits right with New Zealand's weather extremes. TidyUp® adhesive delivers consistent seams that don't telegraph through the paint line twelve months on.

Both are our proprietary systems, developed specifically for the profiles we make, not off-the-shelf compounds repackaged under our name.

03, Custom

If it isn't in the catalogue, we'll make it.

Roughly a third of what we produce every year is bespoke, either a heritage-match to an existing damaged profile, or an architect-drawn detail that doesn't exist anywhere in stock. Send us a photograph, a drawing, or a fragment. We'll quote the piece.

Film and theatre productions, one-off architectural features, restoration projects that need period-accurate replication, all handled through the same team and the same standards as our catalogue work.

What We Do Best

Pipe insulation is our practice.

01, Pipe Sections

Consistent fit. Clean seams. Reliable performance.

Pre-formed pipe sections are our largest category and the one we've spent the longest perfecting. From phenolic for the chilled lines where thermal value matters most, to Rockwool where fire performance is the spec driver, to fibreglass for the high-volume commercial installs, every section ships sized, cut, and documented.

Mechanical contractors and plumbers who've been specifying Accumen® pipe insulation for a decade keep coming back for the same reasons: the sections fit, the seams dress cleanly, and the technical backup is there when the spec gets challenged.

Preformed fibreglass pipe sections - NZ-made glass-fibre PPS

02, Compliance

Documentation that passes review.

Every Accumen® insulation product ships with the technical data a specifier or council consent reviewer needs: thermal values tested to published standards, fire classifications under NZBC C/AS1 and C/AS2, service temperature ranges, and full BPIR documentation where relevant.

If your project is heading for compliance review and you want to be certain the insulation spec won't get kicked back, talk to our technical team before you lodge. We'll review the detail.

About Accumen® · Est. 1991

Two trades. One standard. Thirty-five years.

Adding value to buildings since 1991.

Accumen® is a New Zealand specialist in two disciplines that, on the surface, have almost nothing in common, architectural mouldings and high-performance thermal insulation. What they share is a single operating standard, a small team who've been doing this for decades, and a belief that how a thing is made matters.

Act 01 · Origin

It started with a single profile.

Accumen® was founded in 1991 by a craftsman who couldn't get the mouldings he wanted for a restoration project. Rather than compromise on the specification, he made them himself, and then made them for the next project, and the project after that.

Accumen® is a trusted name in New Zealand's construction and building materials landscape, with a market presence spanning over 35 years. We have earned a reputation for reliability, innovation, and a "can-do" approach that consistently delivers value across residential, commercial, and specialist construction sectors.

Thirty-five years later, Accumen® still operates from Penrose, Auckland, still makes work by hand, and still takes on the commissions nobody else will touch.

How We Work

Four things we don't compromise on.

Take the call

If you can find our phone number, you can reach us. No gatekeepers, no extensions to navigate. The people who answer can actually help.

Say yes to hard briefs

Most of our best work is commissions other suppliers turned down. Heritage-match pieces, one-offs, extreme compliance, this is where we're most useful.

Document everything

Every product has the required technical data specifics and consent reviewers need. No need to scramble trying to find files, just ask the team.

Hold the standard

Two divisions, one consistent standard of care. What gets signed off on a heritage façade is the same care that gets signed off on a plant-room pipe run.

Frequently Asked Questions

Questions we get all the time.

Thirty-five years of answering the same questions means we've got the answers sorted. Can't find yours? Phone 09 270 9228, we'd rather talk to you anyway.

Once the outside cladding is up and the wall areas have been made weather tight.

A tradesperson will be required to install, plaster or mesh and plaster any joins, and patch up any holes that may have occurred when using mechanical fixings to help hold the columns and details in place, in conjunction with adhesive plaster.

We are able to provide you with details of plastering companies who are proficient in installing decorative products manufactured by Accumen® Shapes Ltd. For overseas customers we will provide installation details on a project by project basis.

Yes we can, but the most economical way to purchase mouldings is in 2.7 metre lengths. Due to the size of window or door openings often being a lesser length, it is often practical to order up the lengths in sizes to suit the opening (to cut down on joints).

We provide the following plaster finishes:

Spray sponge finish

Trowel sponge finish (most common)

Trowel smooth finish

Trowel very smooth finish (ideal for internal use)

Other finishes by special request

Our stock range and most of our mouldings are made with a trowel sponge finish which blends in well with most exterior surfaces. However, we are able to provide other types of finishes on our mouldings when required.

Yes, we export product to a number of overseas destinations.

Yes, if you supply us with the overall length of the sills including adding on the return mitre either side of the opening. If there is an architrave either side, remember to include this measurement in the overall length. We will then supply the sills made to length with the return mitres on each end ready for installation.

Email us for a worked example.

Accumen® Shapes decorative mouldings and details can be fixed to most types of wall material including solid plaster, brickwork, concrete, concrete block, AAC panel, cement board, plywood, wood and most other known wall material.

Expansion joints should be discussed per project. Decorative mouldings that go around a building are not safety belts. All buildings move. Extra expansion joints are recommended and should be considered.

Pre-installation requirements are covered in the Mouldings Install Manual (PDF). If you'd like a printable pre-install checklist for site use, contact our team.

We strongly recommend that informed and competent tradespersons install the decorative mouldings and details. This may include but is not limited to the following:

Using a recommended adhesive (e.g. TidyUp® adhesive plaster, supplied by Accumen® Shapes Limited)

Use of stainless steel mechanical fixings

Meshing and plastering joins

Using expansion joints

Sealing the decorative mouldings and details to the building

Making the fixed decorative mouldings and details weather tight

Simply ask us to remove an angled section of the cornice that is going into the corner. This will give you the ability to roll the cornice as you install it, to help alleviate possible gaps on the wall or eave.

LRV is a measurement that tells you how much light a colour reflects, and conversely how much it absorbs. LRV runs on a scale from 0% to 100%. Zero is absolute black; 100% is a perfectly reflective white. Dark colours with low LRV tend to reflect little light while absorbing lots of heat energy, whereas light colours with high LRV reflect a lot of light and absorb less heat energy.

The LRV of the paint colour that is to be applied over decorative details must be as per the specification of the plaster system or cladding company.

Once mouldings are installed correctly, and the adhesive, touch-ups, and joins have been made good and dried, they must be either painted or recoated in a specifically designed plaster as soon as possible.

If painted, Accumen® Shapes Ltd recommend two coats of flexible sealer and two coats of flexible paint. The preparation and application of any paint going on to the moulding should follow the same instructions a paint company would give for applying any sealer and paint on to a raw concrete or plastered wall.

The LRV (Light Reflectance Value) of the paint colour must be as per the specification of the plaster system or cladding company.

Any accumulation of dirt or similar that may occur should be regularly removed from the external surface by cleaning with warm water and detergent and a soft broom. Solvent-based cleaners should not be used.

Like any standard cladding system, the moulding should be checked annually for damage and possible water entry. Any damage which may have occurred must be repaired using professional trade practice. Any paint film damage must be repaired as soon as possible.

It will be necessary to repaint the building in accordance with the paint manufacturer's instructions at certain intervals. The paint manufacturing company should be contacted to confirm the life expectancy of the paint system.

Custom Detail: Please enquire, lead time depends on complexity and whether the detail is manufactured in DecraShape®, fourPLUS®, or ShapeCrete®.

Note: Lead times do not include transport time.

We offer a range of high-performance insulation solutions, including Phenolic foam boards, pre-formed Phenolic pipe insulation, and custom-fabricated thermal cladding components.

Most products are engineered for superior thermal resistance, fire safety, and moisture control, branded under our in-house AccuThermax™ umbrella.

AccuThermax™ Phenolic features a closed-cell, fibre-free rigid phenolic foam core with a factory-applied aluminium-foil vapour-barrier jacket.

Our insulation systems are commonly specified for commercial and industrial buildings, HVAC infrastructure, mechanical pipework, and high-spec environments requiring Group 1 fire performance and thermal efficiency.

Our Phenolic-based insulation solutions, including fourPLUS® and AccuThermax™ Phenolic boards, achieve Group 1 fire ratings and comply with AS/NZS 1530.3 and ISO 5660 standards. They're suitable for use in high-safety zones such as risers, plant rooms, and return-air plenums.

Yes. Our Phenolic insulation products are tested to meet or exceed requirements under the New Zealand Building Code (NZBC) as well as the relevant ISO and AS/NZS standards for fire, thermal, and durability performance.

Depending on the thickness, our Phenolic boards typically offer R-values from R1.1 (at 25 mm) to R3.3 (at 75 mm), delivering superior insulation performance in minimal space compared to other materials.

Yes, when protected and sealed correctly. AccuThermax™ Phenolic boards are water-resistant and robust enough for ventilated façades, parapet insulations, and other areas requiring weather protection.

Yes. Our pre-formed AccuThermax™ Phenolic pipe insulation is specifically designed for HVAC and mechanical service pipework, handling hot-water and heating services up to +120 °C, chilled water, and refrigeration / low-temperature process pipework down to −180 °C.

Information you should consider

Decorative mouldings may be water-repellent in themselves, but due to the diverse situations they may be used in, they are not to be used as a weather-tight material. Architects and competent tradespersons must follow professional trade specifications for the application of a weather-tight membrane on the building before fixing Accumen® Shapes Ltd decorative products. We strongly recommend that informed and competent tradespersons fix the mouldings and shapes.

Installation methods should be clearly understood before installing decorative products manufactured by Accumen® Shapes Ltd.

Construction using Accumen® Shapes Ltd products must be in accordance with good building practice, the New Zealand Building Code, and all statutory and relevant New Zealand standards.

The information contained in this website is true and accurate to the best of Accumen® Shapes Ltd's knowledge. However, the performance data quoted herein is subject to variation dependent upon the quality of workmanship, the base material, and atmospheric conditions, which may be entirely beyond the Company's control before and after installation. Any Accumen® Shapes Ltd warranty is therefore limited to the quality of goods supplied ex factory.

DecraShape® load test — 92 kg standing on the moulding, holds

A system built to hold detail.

DecraShape® was developed in our workshop to solve a specific problem: how to reproduce the profile density of Victorian and Edwardian interior work without the weight, cost, or brittleness of traditional plaster casting.

The material is lightweight, dimensionally stable, and takes fine detail. A DecraShape® cornice can carry seven or eight distinct profile elements, dentil bands, cyma curves, beads, fillets, without the compound weight that makes heritage plaster installs so hard on timber ceilings.

Each length ships plaster-finished and ready for sealing. Apply a flexible sealer then a flexible trade paint - works equally well for interior and exterior runs. Joints are finished with our proprietary TidyUp® adhesive for clean, invisible seams.

DecraShape detail on a classical luxury home, Orakei

Why DecraShape®

Six things this system does well.

Holds fine detail

Profile density comparable to traditional plaster, sharp edges, crisp transitions, no softening of detail during production.

Lightweight construction

Significantly lighter than cast plaster, easier to handle, faster to install, reduced structural loading on ceilings.

Bespoke profiles

Custom patterns made to order from a physical sample, drawing, or template. Heritage matching a specialty.

Stock catalogue

Large library of off-the-shelf profiles for standard spec work, Victorian, Edwardian, and contemporary ranges.

Plaster-finished, paint-ready

Ships plaster-finished, ready for sealing then standard trade paint (two coats sealer, two coats flexible paint), including high-end finish ranges, take to the surface without special prep.

Installer-friendly

Designed to be cut, joined, and installed by any competent builder. TidyUp® adhesive creates invisible seams.

Applications

Classical detail with material weight.

Dentils are small, evenly spaced blocks used as decorative elements on cornice mouldings. Their name comes from the Latin dens, meaning "tooth," and they create the appearance of a row of teeth along the edge of a structure. Common in classical and neoclassical architecture, dentils add rhythm, detail, and elegance to cornices.

Common uses for dentils: enhancing cornice mouldings on homes and buildings, adding ornamental detail to gables, eaves, and rooflines.

Corbels are projecting architectural brackets that support - or appear to support - a structural element such as a beam, shelf, or cornice. Traditionally carved from wood or stone, corbels serve both structural and decorative purposes.

Exterior corbels are often featured beneath eaves, large cornices, or window sills, adding visual interest and a sense of craftsmanship. All our dentil and corbel work is produced in ShapeCrete®, the cast-finish system that gives this detail the weight, depth, and material authenticity it needs.

fourPLUS® load test — vehicle wheel on a 110×40 moulding, uncrushed

fourPLUS® finished — painted Corinthian capital

Built for what the weather does.

fourPLUS® was developed to replace the traditional exterior-moulding solutions, cast stone, timber, or heavy plaster, that either cost too much, weigh too much, or don't last. The composite structure is specifically engineered for New Zealand and Australian climate conditions.

The material is UV-stable and resists the dimensional movement that plagues timber mouldings exposed to sun. It doesn't absorb water the way plaster does, so freeze-thaw and salt-spray degradation are effectively eliminated. And it's light enough that fixing detail doesn't need to over-engineer for dead load.

Every fourPLUS® commission ships with full documentation, cross-sections, install detail, and the compliance statements consent reviewers look for.

Why fourPLUS®

Six things this system does well.

UV stability

Formulated to resist colour shift, surface degradation, and dimensional creep from long-term sun exposure.

Water resistant

Does not absorb water. Eliminates the freeze-thaw failure mode that destroys traditional exterior plaster work.

Profile stability

Holds its shape through thermal cycles and humidity changes that would distort timber or softer composites.

Lighter than stone

Comparable aesthetic weight to cast stone but a fraction of the actual mass, simpler fixing, lower structural loading.

Plaster finish, paint-ready

Ships plaster-finished. Apply a flexible sealer first, then exterior-grade acrylic or solvent-based paint - no special preparation required.

Profiles to match

Full library of façade profiles, cornices, quoins, columns, dentils, bandings, plus bespoke made to order.

Applications

ShapeCrete®, when weight is part of the aesthetic.

ShapeCrete® is our cast concrete moulding system. It's the right specification when a building's architectural language calls for mass, for heritage commercial restoration, structural-looking columns, or any project where the material itself is part of what the façade is saying.

Manufactured from

Decorative lightweight concrete shape with mesh; larger shapes use reinforced rod. Solid lightweight concrete - can be supplied in lengths up to 2.700 m depending on size and shape. The right call for historic buildings and areas requiring a safeguard from impact. Solid concrete

Commercial-scaleUse case

The material matters.

ShapeCrete® is Accumen®'s cast concrete system. It's not the right system for every project, the weight and install complexity rule it out for most residential work, but when a commission calls for it, nothing else does the job.

The reason to specify ShapeCrete® is that cast concrete reads as cast concrete. On a heritage restoration where the original material was cast stone, or on a commercial façade where the architectural vocabulary is weight and permanence, a lightweight substitute would be visually wrong even if dimensionally correct.

Every commission is made to order. We work from the sample or drawing, mould the profile in our workshop, and deliver crated and ready for install with lifting and fixing details supplied with every piece.

AccuThermax™ Insulated Plasterboard - plasterboard lining laminated to phenolic foam core

Product features

Why specifiers choose it.

Low thermal conductivity

High-performance rigid phenolic insulation core, λ = 0.023 W/m·K at 15 °C. Among the lowest thermal conductivity values available in a board format at this thickness range.

3-in-1 build-up

Insulation, interior lining, and vapour control in a single board. Eliminates the labour and coordination of separate insulation, lining, and barrier layers.

Slim profile, more floor area

The combined build-up is meaningfully thinner than bulk insulation plus separate lining. On commercial projects this can translate into measurable extra usable floor area.

Fibre-free core

Closed-cell phenolic foam, no loose fibres. Easier to cut, handle, and finish on site than fibre-based insulation alternatives.

Vapour-resistant

Resistant to water vapour transmission, helping manage internal moisture risk when detailed correctly. Reduces reliance on a separate vapour barrier in many wall and ceiling build-ups.

Substrate-flexible

Compatible with timber and steel framed construction, and direct-fixed to masonry or concrete substrates. The same product solves multiple wall types across a project.

Fire-tested core

Phenolic core fire performance to AS 1530.3: zero spread of flame and very low smoke development. System-level fire performance assessed as part of the completed wall or ceiling build-up.

Low environmental impact

Manufactured with a CFC/HCFC-free blowing agent, with zero Ozone Depletion Potential (ODP) and low Global Warming Potential (GWP).

Independent test reports are available to BCAs and specifiers on request, complete and unaltered — contact info@accumen.co.nz.

AccuThermax™ Phenolic Range

Not all foams are
created equal.

Same blowtorch. Same flame. XPS ignites in 3 seconds. PIR in 7. EPS melts away. After nearly nine minutes of continuous direct flame, the phenolic board has only charred where the torch touches — no ignition, no burning droplets, minimal smoke. Watch it happen, then see the numbers behind it.

Phenolic: char only — never ignites

Unedited torch test: rigid phenolic board side-by-side against elastomeric rubber, PIR, XPS and EPS. Demonstration only — classified fire performance per EN 13501-1 and AS/NZS 1530.3 test reports below.

Why Phenolic

Every insulation foam makes a trade-off. EPS is cheap but burns. PIR insulates well but smokes. Rubber is flexible but thick. Phenolic foam doesn't trade — it pairs the best thermal performance in the category with outstanding fire behaviour, a >95% closed-cell structure that blocks moisture, and a service range that runs from cryogenic to hot water.

That's why it's the standard specification in the UK and Hong Kong, and insulates landmarks from the Burj Khalifa to the Channel Tunnel. Now it's made here.

The physics, in two pictures

Same R-value. Half the bulk.

Insulation thickness scales directly with conductivity. Because phenolic sits at 0.023 W/m·K, it hits the same R-value as EPS at roughly 40% less thickness — that's real ceiling space, tighter risers, and smaller penetrations on every run.

Wall thickness required for equal thermal resistance (flat-wall basis, typical λ values)

Closed cells. Dry insulation. Protected pipes.

Wet insulation barely insulates — and condensation under the jacket is what corrodes pipework. Phenolic's >95% closed-cell structure, sealed behind a factory-applied foil vapour barrier, stops moisture migration and internal condensation cold.

Fibre-free, halogen-free and with no added chlorides, it's clean to handle and supports stainless steel pipework, subject to system design.

One chemistry, every density

Phenolic isn't one product — it's a platform. From 40 kg/m³ pipe sections to high-density support blocks that carry the pipe itself, the whole system is phenolic: one chemistry, one fire class, no weak links at the supports.

AccuThermax™ Phenolic Board — foil-faced rigid phenolic foam board

Industrial board, built to carry load.

AccuThermax™ Phenolic Board is a closed-cell rigid phenolic foam board (Resolution® phenolic core) offering an exceptional combination of compressive strength, low thermal conductivity and strong fire performance — supplied plain (unfaced) or foil-faced, at nominal densities of 40, 80 and 120 kg/m³.

Its high strength-to-weight ratio and dimensional stability make it well suited to load-bearing thermal insulation duties where conventional low-density insulants are unsuitable. The 40 kg/m³ grade is the general-purpose board of the range; the 80 kg/m³ grade remains lighter and easier to work than the 120 kg/m³ grade; the 120 grade carries the highest compressive loading.

Typical applications: tapered crickets, saddles and sumps beneath waterproofing membranes on flat and low-slope roofs; support and packer boards for rooftop plant, plinths and upstands; load-bearing insulation inserts and support blocks for pipework and equipment; rigid building insulation to framed walls, ceiling (soffit) linings and roofing (40 grade); and general thermal insulation where compressive loading or service temperatures up to 120 °C apply.

Boards can be cut, profiled or tapered to order. Full test reports and generic phenolic foam characterisation data are available from Accumen on request.

The 80% of heat loss most people miss.

The slab edge of a foundation can be responsible for approximately 80% of the slab's total heat loss. Further research shows that thermal resistance does not significantly improve by fully extending insulation under the slab - the critical detail is at the slab edge.

Accumen® are the New Zealand manufacturers of AccuThermax™ XPS, the rigid extruded polystyrene used in our AccuThermax™ Slab-Edge Insulation system. AccuThermax™ XPS is produced without the use of toxic, ozone-depleting substances - the environmental choice for any project.

SEI is designed to retain heat efficiently, reduce energy consumption, and maintain comfortable temperatures year-round. Compliant with the latest H1 thermal performance pathways for NZBC.

Why specifiers choose SEI

Engineered for where it matters most.

Targets ~80 % of slab heat loss

Slab edge is where most foundation heat loss occurs. Insulating here is more effective than insulating under the slab.

Pre-plastered, ready to fix

Boards arrive pre-plastered and ready to install. The plaster face is the finished face - no separate plastering trade required.

AccuThermax™ XPS substrate

High-density extruded polystyrene with high compressive strength. Carries the load and the rendered face for life.

Practically impervious to water

Closed-cell XPS structure means moisture exposure at the slab edge doesn't degrade thermal performance.

35+ years of pre-plastered experience

Same proven pre-plastered technology Accumen® has used for decorative shapes and mouldings for three decades.

Made in NZ

Manufactured in-house at our Penrose facility. Real lead times, real local stock, real local support.

The "secret sauce" for moulding install.

TidyUp® is Accumen®'s own uniquely modified cement-based adhesive plaster that is recommended for use by tradespersons for installing Accumen® mouldings and shapes.

TidyUp® adhesive plaster is designed for fixing decorative mouldings to a weathertight surface using a notched trowel. We supply TidyUp® in convenient 4 L or 10 L resealable buckets, for ease of storage and carrying around difficult building sites.

Decorative mouldings may be water repellent in themselves, but due to the diverse situations they may be used in, they are not to be used as a weathertight material. Architects and competent tradespersons must follow professional trade specifications for the application of a weathertight membrane on the building before fixing Accumen® decorative products.

We strongly recommend that informed and competent installers fix the mouldings and shapes. Installation methods should be clearly understood before installing decorative products. Accumen® can recommend professional plasterers throughout New Zealand who are available to assist you with installation.

Auckland Art Gallery

Innovative moulding techniques used to create unique concrete shapes for the Auckland Art Gallery, enhancing its architectural beauty while collaborating closely with project managers and architects.

Key products used ShapeCrete® Custom Mouldings

LocationAuckland CBD

CategoryPublic & Cultural

The brief.

Auckland Art Gallery's heritage wing required architectural shape work that could carry the weight of a public-institution finish without overloading the existing structure. The project managers and architects needed a supplier who could collaborate at the spec stage, not just deliver to a drawing.

Our approach.

We worked through the detail directly with the architects, producing innovative concrete shapes in ShapeCrete® that read as cast masonry from gallery sightlines but were engineered for the structural envelope. Each component was sample-matched against the heritage profile language of the wider building.

Outcome.

The finished pieces sit in one of the country's most-visited public buildings, reading exactly as cast stone would but at a fraction of the structural load. The collaboration with the gallery's project team was the difference - every detail was a conversation, not an invoice.

CategoryCommercial / Hospitality

The brief.

Hilton signed off on a Taupō property with strict brand-architecture standards. Every parapet line, every architrave around the upper-floor openings, every horizontal groove that defined the building's modern-classical rhythm had to read crisp from across Lake Taupō.

Our approach.

We supplied the full façade moulding set in fourPLUS® - UV-stable, dimensionally tight under lakeside exposure, plaster-finished and ready for sealing + the brand paint spec. Delivery was sequenced against the cladding programme so nothing sat on site and no trade above was held up.

Outcome.

From the lake the building reads as the engineered brand expression Hilton spec'd. From the construction team's perspective, the moulding work cleared the programme without holding up a single trade - that's the quiet measure of a successful hospitality fit-out.

The brief.

Carnegie Library in Thames stands as a heritage civic building with intricate façade work - fluted columns, decorative cornices, and intricate keystone detail. The restoration brief was to preserve the classical reading while bringing the building back into compliance.

Our approach.

We worked from surviving original profiles, sample-matched to the building's specific dentil rhythm and column entasis. ShapeCrete® carried the heavier base elements; DecraShape® reproduced the finer interior detail. Every replacement piece registered against the existing for invisible joints.

Outcome.

The library reads as it did when Andrew Carnegie's name first went on the door. The traditional elements are reproduced; the modern building code compliance is invisible. Locals walk past without noticing the work was ever done - which is exactly the point.

Key products used fourPLUS® Custom Mouldings

LocationAuckland

CategoryResidential

The brief.

An Auckland project required architectural chimney work in a modern composite finish - grey siding, elegant finials, durability against Auckland's prevailing weather without aesthetic compromise.

Our approach.

We produced the chimney shapes and finials in fourPLUS® for the exterior durability spec, with custom siding-compatible detail at the base junction. Every component was profile-matched against the architect's drawings before manufacture.

Outcome.

The chimneys define the roofline of the property without dominating it - exactly the architectural balance the brief specified. The fourPLUS® system means the finish will hold through years of Auckland sun, wind, and rain.

Balusters Auckland

Accumen® Shapes custom-made 195 ShapeCrete® balusters, each one metre high, designed to meet stringent strength tests and installed to support a durable banister in an Auckland residential new build project.

Key products used ShapeCrete® Custom Mouldings

LocationAuckland

CategoryResidential / New Builds

The brief.

An Auckland residential new-build needed 195 balusters - each one metre tall, each engineered to pass strength testing for a load-bearing banister. Standard production wasn't an option for the volume and the strength spec.

Our approach.

We custom-cast 195 ShapeCrete® balusters to the architect's profile, with embedded reinforcement engineered to the building consent's load case. Each baluster was tested against the strength requirement before despatch.

Outcome.

The balustrade now runs the perimeter of the property - every one of 195 components reading as a matched set, every one passing the strength test it was designed for. That kind of volume in custom architectural product is what specialised manufacturing exists for.

Balustrade Restoration

Urban apartment building restoration focusing on revitalising original balustrades while enhancing safety and aesthetic appeal. The project preserves historical character while meeting modern safety standards through skilled craftsmanship and quality materials.

Key products used ShapeCrete® Custom Mouldings

LocationAuckland

CategoryCommunity / Public

The brief.

An urban apartment building needed its original balustrades restored to combine historical character with modern safety code compliance. Two requirements that often pull in opposite directions.

Our approach.

We sample-matched the original baluster and rail profile, reproduced in ShapeCrete® with embedded structural anchors specified to the current loading code. The original visual reading was preserved while the underlying performance was lifted to current standard.

Outcome.

From the street the building looks as it did when first built. From the building manager's perspective, the balustrade now passes every current code inspection - historical character protected, modern safety underwritten.

Key products used DecraShape® fourPLUS® Cornices Columns Custom Mouldings

LocationNew Zealand

CategoryResidential / New Builds

The brief.

A residential new-build project wanted an entrance that read as classical architecture without the build cost or weight that traditional cast stone would have required. Elegant columns and intricate cornice detail were specified.

Our approach.

We supplied the column shafts and capitals in DecraShape® for the lightweight feature work, the cornice in fourPLUS® for the exterior weather spec. Each component was registered against the entrance proportions for harmonious composition.

Outcome.

The entrance now reads as a piece of classical residential architecture - proportions that work, detail that reads correctly, finish that will weather without losing the profile that was specified.

The brief.

A basic rectangular building needed to be transformed into a building that read as an elegant villa. Decorative shape work was the architect's chosen lever.

Our approach.

We supplied a coordinated suite of decorative DecraShape® elements - façade detailing, cornice runs, and feature mouldings - designed against the existing wall proportions to give the building a coherent classical reading.

Outcome.

The transformation is complete: a rectangular building now reads as a villa, with the architectural language and proportional discipline that name implies. Shape work is one of the most cost-effective transformations available to residential architecture.

Villa Restoration

Expert restoration of a historic villa featuring meticulous reconstruction and high-quality materials. The building was partly demolished and then reconstructed using only the best materials available. Accumen® Shapes reproduced custom mouldings and decorative architectural elements.

Key products used DecraShape® ShapeCrete® Custom Mouldings

LocationNew Zealand

CategoryResidential / Heritage

The brief.

A historic villa was partly demolished and required reconstruction. Only the best materials would do - the original architectural language was the cornerstone of the project's value, and the new work had to read as the old.

Our approach.

We reproduced custom mouldings and decorative detail against the surviving original profiles. ShapeCrete® carried the heavier cast-stone passages; DecraShape® reproduced the finer interior detail. Every component was profile-matched before despatch.

Outcome.

The villa now reads as it did at the start of the 20th century, with the modern structural performance and seismic compliance the partial reconstruction afforded. Heritage value preserved, modern building code underwritten.

LocationNew Zealand

CategoryRestoration

The brief.

A historic property's fence and gate needed restoration with new concrete foundations and decorative elements. The aesthetic value of the original work had to survive the structural overhaul.

Our approach.

We supplied custom decorative shapes that registered against the existing fence-post architecture, with concrete-compatible fixings engineered for the new foundations. The reading from the street is unchanged; the structural integrity is current.

Outcome.

The fenceline reads as the property's original boundary, but the underlying concrete foundations are new and built to code. Restoration that respects what was there while bringing the structure forward.

Stanbeth House, Auckland

A restored building featuring new column capitals and architraves with centre keystones for nine arches on the ground level, supplied by Accumen® Shapes.

Key products used ShapeCrete® Columns Architrave Bands Custom Mouldings

LocationAuckland

CategoryHeritage / Commercial

The brief.

Stanbeth House on Auckland's Customs Street is late-1800s commercial architecture with nine ground-level arches. The restoration brief was to reproduce all nine column capitals and all nine arch keystones - and they had to read as a single matched set.

Our approach.

On paper that's nine of one thing. In practice each arch sits in a slightly different structural context - corner arches carry more lateral load, the centre arch has additional dead load. We supplied each capital and keystone in ShapeCrete® with embedded stainless fixing points engineered per-arch to match the underlying load path.

Outcome.

The arches now read as a matched set from the footpath. Look closely at the keystone fixings and each one has its own anchor pattern - invisible, but right for that arch's load. Stanbeth is back in tenancy with the original architectural language intact.

The brief.

CIMA Building, Parnell - a modern commercial retail building with sleek aluminium accents, expansive windows, and innovative moulding work that emphasised natural light and contemporary architectural language.

Our approach.

We worked with the architect to produce moulding sections that complemented the modern aluminium and glass without competing with them. DecraShape® held the finer details; fourPLUS® carried the exterior runs against Parnell's prevailing weather.

Outcome.

CIMA now reads as the modern commercial expression the architect designed - a building where the moulding work supports the wider architectural composition rather than dominating it. The right system for the right surface, every time.

Key products used ShapeCrete® Custom Mouldings

LocationGrey Lynn, Auckland

CategoryPublic / Heritage

The brief.

Grey Lynn Library's 1924 façade carries historical garlands that needed restoration. The building's architectural beauty depended on this decorative detail reading correctly - a single mismatched profile would have broken the rhythm.

Our approach.

We sample-matched the original garland profile against the few surviving original pieces, reproduced in ShapeCrete® for the visual weight, and supplied with embedded fixings tested against the existing wall substrate. The plastering trade did the rest.

Outcome.

The Grey Lynn Library now reads as it did in 1924 - the garlands continuous, the architectural rhythm preserved. A century-old civic building back in its full architectural voice.

The brief.

A residential façade transformation called for restored sash windows and an enhanced entrance door. The brief was to modernise the curb appeal without losing the brickwork's traditional character.

Our approach.

The brief.

A retail space in Ponsonby wanted Ionic Capitals on Half Fluted Columns to give the storefront classical architectural language. Spiral scrolls inspired by ram horns - the architect was specific.

Our approach.

We custom-produced the Ionic Capitals in ShapeCrete® with the spiral scroll detail to the architect's exact profile. The Half Fluted Column shafts came in DecraShape® for lightness and ease of fixing against the retail interior wall substrate.

Outcome.

Ricochet now reads with the classical architectural presence the brand wanted - Ionic capitals catching light from above, fluted column shafts running clean down to the floor. Retail architecture that takes itself seriously.

LocationChristchurch

CategoryCommercial / Mixed-use

The brief.

A Christchurch revitalisation project on St Asaph Street needed decorative mouldings that softened the original structure's appearance - curved shapes and fine detail that brought architectural warmth to the façade.

Our approach.

We worked from the architect's curve specifications, producing lightweight DecraShape® mouldings that registered cleanly against the existing wall substrate. fourPLUS® carried the exterior face where weather durability mattered most.

Outcome.

The building now reads with architectural warmth where it was previously austere - and the affordability of the moulding approach made the architectural lift feasible within the project budget. An affordable way to genuinely upgrade architectural quality.

Elegant Art Deco signage panel cast in ShapeCrete® with recessed lettering by Accumen® Shapes, reinforcing building identity in Napier, New Zealand's Art Deco capital.

Key products used ShapeCrete® Custom Mouldings

LocationNapier

CategoryCommercial / Signage

The brief.

Napier is New Zealand's Art Deco capital and the brief was an elegant Art Deco signage panel that reinforced building identity. ShapeCrete® was specified - recessed lettering, cast finish, weight that read as authentic period work.

Our approach.

We cast the signage panel in ShapeCrete® with recessed lettering to the architect's exact typography. The composition was sized against the building's existing Art Deco proportions so the signage reads as part of the original architecture, not retrofit.

Outcome.

The signage now reads as if it had been part of the building since the 1930s - period-correct typography, period-correct material weight, period-correct integration with the surrounding architecture. Napier deserves no less.

CategoryBBold / Bespoke

The brief.

A large Prada Cup replica was commissioned for display - H-grade kiln-dried EPS over a steel frame, formed using advanced 3D machining for precise formwork replication with rapid turnaround.

Our approach.

We CAD-modelled the cup geometry from official references, 3D-machined the form against the steel substrate, and finished to a display-grade surface in a fraction of the turnaround a traditional moulding would have required. Engineering speed met sculptural accuracy.

Outcome.

The replica is dimensionally faithful, structurally sound, and was on display when the brief required it - not later. 3D machining of EPS substrate is one of the genuinely transformative recent capabilities in architectural shape work.

The brief.

An educational building called for 36 square frame infills in DecraShape® with detailed cornices - a repetitive architectural pattern that needed to read as deliberate composition, not mass production.

Our approach.

We custom-produced 36 matched frame infills with cornice detail registered to read continuously across the building envelope. The repetition is the architecture - the arches and frame rhythm define the building's reading from the street.

Outcome.

The completed structure shows what 36 identical architectural components can do when they're spec'd as a composition rather than a list. The arches read as a unified architectural statement - exactly the educational identity the school wanted.

The brief.

A retirement village specified cost-effective Accumen® false shutters to lift the visual appeal of standard-design homes. Customisable widths and lengths were essential - every house plan was slightly different.

Our approach.

We produced the false shutters in standard stock profile but custom-cut to each dwelling's openings. The architectural reading is uniform across the village; the underlying customisation is invisible to residents and visitors.

Outcome.

The retirement village now reads as architecturally considered rather than utilitarian - a quality the residents notice and the developer's marketing benefits from. False shutters are one of the highest-return architectural lifts available to residential at scale.

The brief.

An ongoing residential transformation at Riverhead called for custom lightweight architectural mouldings to replace imported timber detailing - a switch to locally-manufactured DecraShape®, fourPLUS®, and ShapeCrete® components for both elegance and supply-chain reliability.

Our approach.

We worked through the architect's spec sheet to translate each timber detail into the correct Accumen® system - DecraShape® for the interior cornice work, fourPLUS® for the exterior runs, ShapeCrete® for the heavier feature elements. Local manufacture meant lead times the imported alternative couldn't match.

Outcome.

The mansion is now under transformation with locally-supplied architectural detail that will outlast the imported alternative - and was on site when the build programme called for it. New Zealand-made architectural product, sized for ambitious residential.

Taupō Home

A residential revitalisation project featuring Accumen® lightweight mouldings that enhanced the building's aesthetic appeal and added considerable property value.

Key products used DecraShape® Cornices Architrave Bands Custom Mouldings

LocationTaupō

CategoryResidential

The brief.

A Taupō home was revitalised with Accumen® lightweight mouldings to enhance aesthetic appeal and add property value. The brief was architectural lift, not architectural showpiece.

Our approach.

We supplied a coordinated set of DecraShape® mouldings designed against the existing residence - cornice, architrave, and feature detail all sized to register correctly against the building's existing proportions. Architectural enhancement that integrates rather than dominates.

Outcome.

The Taupō home now carries the architectural authority that adds genuine property value - visible to anyone walking past, instinctively readable as a residence that has been treated with architectural care. Property value follows architectural quality.

Tauranga

A striking modern Art Deco home featuring Accumen® architectural mouldings. The captivating architecture combines parapet mouldings, architraves, sills, and exterior skirting to enhance visual appeal.

Key products used fourPLUS® Architrave Bands Custom Mouldings

LocationTauranga

CategoryResidential

The brief.

A striking modern Art Deco home in Tauranga combined parapet mouldings, architraves, sills, and exterior skirting to enhance visual appeal. Art Deco at residential scale is a discipline - every proportion has to be right.

Our approach.

We produced the full Art Deco moulding suite in fourPLUS® for the exterior weather spec - parapet runs, architrave detail, sill and skirting components all sized against the building's specific Art Deco grammar. The component-level discipline is what makes Art Deco read correctly at residential scale.

Outcome.

The Tauranga home now reads as confident Art Deco residential - parapet line clean, architrave proportions correct, every component sized for the architectural rhythm Art Deco demands. Residential Art Deco done with the discipline the style requires.

LocationTe Aroha

CategoryCommercial / Heritage

The brief.

Mason's Lodge No. 52 in Te Aroha, originally built in 1884, was completely dismantled and reconstructed using original bricks. The decorative mouldings had to be recreated to match the original designs from scratch.

Our approach.

Working from photographs and surviving fragments, we sample-matched the original moulding profiles and produced replicas in ShapeCrete® and fourPLUS® for the exterior work. Each piece was registered against the reconstructed brickwork for invisible joinery.

Outcome.

Mason's Lodge No. 52 stands reconstructed - original bricks, recreated moulding work that reads as the 1884 originals, modern seismic and building code compliance underwritten. A heritage project done with the patience the work demanded.

T Adair, Gisborne

Restoration of a historic building in Gisborne that was damaged by a 2007 earthquake and subsequent fire. The project involved expert plastering and installation of ShapeCrete® lightweight concrete mouldings supplied by Accumen® Shapes.

Key products used DecraShape® ShapeCrete® Custom Mouldings

LocationGisborne

CategoryCommercial / Heritage

The brief.

T Adair in Gisborne suffered damage from the 2007 earthquake and subsequent fire - a historic building that required expert restoration to bring it back. Plastering and the installation of lightweight concrete mouldings would carry the architectural work.

Our approach.

We supplied ShapeCrete® lightweight concrete mouldings designed against the surviving original profile language, plus DecraShape® feature detail for the interior. Every component registered against the building's reconstructed envelope for invisible joinery.

Outcome.

T Adair stands restored as a survivor of one of New Zealand's most disruptive recent events - earthquake-damaged then fire-damaged, now back as the Gisborne heritage building it always was. Restoration done with the care the building deserved.

Old Choral Hall - Portico Reinstatement

Accumen® collaborated with Architectus, Aspect Construction and Allied Exteriors to reinstate the Old Choral Hall portico using 3D scanning, printing, and precision moulding to reproduce heritage profiles - delivering over 1,500 components with millimetre accuracy for the University of Auckland.

LocationAuckland

CategoryHeritage / Educational

ArchitectArchitectus

BuilderAspect Construction

PlastererAllied Exteriors

The brief.

When the University of Auckland decided to reinstate the original Old Choral Hall portico, the brief was unambiguous: every profile, every dentil, every cornice run had to read as the 19th-century original. Drawings alone weren't going to get us there - this needed measurement-first restoration.

Our approach.

Working with Architectus, Aspect Construction and Allied Exteriors, we approached the job as a measurement problem first. Surviving fragments were 3D-scanned where possible; where they didn't exist, geometry was inferred from historical photographs and matched to typological patterns. Over 1,500 individual components were produced.

Outcome.

The result is a portico that reads as if it had never left. From the street, you wouldn't know which dentils are 1870s and which are 2026. That's the point - and the technical achievement underneath: 3D scanning, 3D printing for proof, precision moulding for the final delivery.

The brief.

Twenty-two columns, each 8.0 metres tall and 800 mm in diameter, delivered to Hoyts Chadstone in Melbourne. Over 400 individual stack-line components produced in New Zealand and shipped across the Tasman in sequence for install.

Our approach.

Columns at this scale don't ship as single pieces. The Hoyts run was split into stack-line sections, designed so that the joint detail disappears once the fourPLUS® coating is applied with the signature smooth finish. We ran a full test stack in Penrose before shipping a single component.

Outcome.

Twenty-two columns up, on time, in another country. By the time the first crate left the wharf, the install sequence was a known quantity, and the on-site team had a stack-up they could replicate without surprise. The kind of brief we built fourPLUS® for.

Tantalus Estate Vineyard, Waiheke Island

The restoration project transformed a historic building into a welcoming destination, featuring a completely replaced bell tower and parapet detail crafted with ShapeCrete® and DecraShape® materials.

PlastererMike May, Plastering.co.nz

The brief.

Tantalus Estate on Waiheke Island wanted to keep its character - a historic building with a distinctive bell tower and a parapet line that defined the vineyard's silhouette against the Hauraki Gulf. The original tower was structurally compromised and the parapet was failing.

Our approach.

Replacing the tower in original-weight stone was off the table on a vineyard site with restricted access. We rebuilt the bell tower in ShapeCrete® for the lower mass and DecraShape® for the upper detailing - visually indistinguishable from the cast-stone original, but a fraction of the structural load. The new parapet went in fourPLUS® for the coastal exposure spec.

Outcome.

From the cellar door across the vines, the new tower reads as it always did. Every piece arrived in transport-friendly sections, registered against the existing footprint within a few millimetres, and went up in days rather than weeks. Heritage hospitality done with the architectural respect the building deserved.

St Kentigern Boys' School - Roselle House Historical Chimneys

Restoration of three intricately detailed masonry chimneys from the late 1800s at one of Auckland's oldest homes. The original chimneys, each weighing approximately 2 tonnes, were decommissioned due to seismic safety concerns and replaced with lightweight replicas using polystyrene and fibreglass-reinforced plaster - reducing weight to just under 200 kg each while maintaining exact architectural detail.

PlastererAccumen® Shapes

The brief.

Roselle House, on the grounds of St Kentigern Boys' School, is one of the oldest homes in Auckland. The three original chimneys, each weighing approximately two tonnes, had reached the point where seismic concern outweighed sentiment. They had to come down.

Our approach.

Working with Salmond Reed Architects, we produced lightweight replicas in polystyrene and fibreglass-reinforced plaster. Each chimney was reproduced in exacting detail from photographs and surviving profile fragments, then finished and weighted to read identically to the masonry it replaced. Final weight per chimney: just under 200 kg, down from two tonnes.

Outcome.

The difference is invisible from the ground. Up close, the detail matches: cornice profiles, base plinth, cap geometry. The change is the load on the structure below, which is now an order of magnitude safer in seismic terms without compromising the heritage character of the building.

Union Fish Building, Auckland

Restoration of the historic Union Fish Building in Auckland, preserving early 20th-century architectural elements and enhancing its original exterior features. The building, constructed in 1904-1906 and located at 116-118 Quay Street, is registered as Category I under the Historic Places Act (1993). Accumen® Shapes created decorative moulded detailing to match original designs, replacing missing significant elements including the elegant parapet roofline.

The brief.

The Union Fish Building at 116-118 Quay Street, Auckland - constructed 1904-1906, Heritage NZ registered - required restoration of its early-20th-century architectural elements and an enhanced reading of its original exterior features.

Our approach.

We sample-matched the surviving original profile language and reproduced in ShapeCrete® for the cast-stone passages and fourPLUS® for the exterior runs. Every component registered against the existing 1906 architecture for invisible joinery and continuous architectural reading.

Outcome.

The Union Fish Building now reads as it did in 1906, with the modern structural compliance and heritage registration responsibilities underwritten. Quay Street's architectural character preserved, one building at a time.

Terms of supply

Last updated 15 May 2026

Plain English summary.

These terms apply when you order from Accumen®, whether you're a homeowner ordering a single letterbox or an architect specifying a full façade package. They cover what we promise, what we expect from you, and how we handle the situations that occasionally come up.

If you'd like to discuss any of these terms before ordering, please call the workshop on 09 270 9228.

Quotes & orders.

Quotes are valid for 30 days from the date we issue them, unless we say otherwise on the quote. Pricing is subject to change after the quote period, typically only by small amounts driven by raw material movement.

Orders are confirmed once we've received written acceptance of the quote and any deposit specified on the quote. For most commissions a 30% deposit is required to commit production capacity.

Bespoke commissions

For bespoke (made-to-order) commissions we typically require a test piece sign-off before committing to full production. The test piece is invoiced separately. Once the test piece is signed off and full production starts, the deposit is non-refundable.

Production & delivery.

Standard insulation items ship in usually 2-5 business days. Mouldings supply: 1-3 weeks depending on project size. Bespoke and specialist commissions have specific lead times agreed at quote stage starts.

We deliver NZ-wide. Australian delivery is available for larger commercial commissions. Freight is charged separately and is non-refundable once the goods have left our workshop.

Risk and title

Risk passes to you on delivery to the address specified on the order. Title remains with Accumen® until payment is received in full.

Warranty.

We warrant our products against manufacturing defects for the warranty periods specified at quote stage. For exterior fourPLUS® and ShapeCrete® work this is typically 12 months from invoice date for manufacturing defects. For interior DecraShape® work this is typically 12 months from invoice date for manufacturing defects.

Warranty doesn't cover damage from misuse, incorrect install, modification, or normal wear. We require photographs and reasonable cooperation in diagnosing any warranty claim.

Install responsibility.

Unless we've been engaged for install (separately quoted), install responsibility rests with you or your contractor. We supply install detailing and phone support, but we're not responsible for installs we haven't carried out ourselves.

If something looks wrong during install, phone the workshop. We'd much rather sort it before the install proceeds than after.

Payment.

Standard payment terms are 7 days from invoice date. We accept bank transfer and credit card. Recurring trade accounts have separately agreed terms.

Overdue invoices accrue interest at 2% per month after the due date. Recovery costs (debt collection, legal fees) are passed to the debtor where applicable.

Cancellations & returns.

Stock items can be returned within 14 days of delivery if undamaged and in original packaging. Restocking fee of 15% applies. Freight costs are non-refundable.

Bespoke and made-to-order commissions cannot be cancelled or returned once production has started, they have no resale value as standard inventory.

Liability.

Our liability for any commission is limited to the value of the commission itself. We don't accept liability for consequential or indirect loss, e.g. delays to a build programme caused by late-arriving freight, or property damage caused by incorrect install of supplied product.

Nothing in these terms excludes liability where it cannot be excluded under the Consumer Guarantees Act 1993, the Fair Trading Act 1986, or other New Zealand law.

Disputes.

If you're unhappy with anything we've supplied, the first step is always a phone call. Most issues resolve over a 10-minute conversation. We genuinely want to make it right.

If a dispute can't be resolved through direct discussion, both parties agree to attempt mediation through the Auckland Disputes Tribunal or equivalent before any court action.

Changes to these terms.

We update these terms occasionally. The version that applies to your order is the version published at the time the order was placed. Material changes are notified to active customers.

Ōrākei House Of The Year 2022
Residential Heritage Project

Location

Ōrākei, Auckland

The project

This luxury home in the Auckland suburb of Ōrākei encompassed a large selection of Accumen® Shapes exterior moulding products to create this Italian-inspired masterpiece.

Our approach

Given the detailed nature of this project, Accumen® Shapes were engaged by Jones Architects Ltd early on in the project to bring the homeowner's vision to life alongside Lewis Build (Builders) and Allied Exteriors (Plasterers / Mouldings Installers).

The project utilised a number of Accumen® Shapes exterior moulding products including arches, dentils and corbels, columns, cornices, fence caps, and balusters for balustrades.

The work

This project required a high level of customisation: the mouldings needed to be lightweight, yet look solid and dramatic. The balusters for the balustrades in particular have been designed to replicate solid concrete - they are lightweight mouldings installed over an engineered steel structure.

The project

The Arches apartment building in Mission Bay is unique in more ways than one. Accumen® Shapes are proud to have supplied the decorative moulding details for this project.

The facade

The aesthetic expression of the facade amongst its neighbours is pleasantly unique: centring coastal cues, the building captures a sculptural quality and an appreciation of traditionally inspired forms.

The dazzling white exterior complements the seaside environment, and the curved archways and custom-made moulding details portray a calming yet sophisticated energy.

Contemporary Art Deco

Key products used DecraShape® fourPLUS® Cornices Columns Architrave Bands Custom Mouldings

The brief

A contemporary Art Deco composition on Great North Road, BurgerFuel's headquarters as an architectural statement, not just commercial premises. The façade language: stepped parapet, winged insignia, twin oculi, and a disciplined grid of recessed panels.

Art Deco is one of those vocabularies that's easy to gesture at and hard to deliver. The proportional language is unforgiving, get the panel grid wrong, get the stepping wrong, get the oculus framing wrong, and the whole façade reads as pastiche. The spec demanded mouldings work that carried the proportional discipline of authentic Art Deco.

Our approach

Accumen® supplied the full suite of DecraShape® and fourPLUS® mouldings that give the façade its form and character, every recessed panel frame, every stepped parapet section, every band that organises the composition.

Production disciplines around the Art Deco grid were tight. Every recessed panel had to align with neighbours along both axes. The stepped parapet sections had to read cleanly against each other at the top of the façade. The twin oculi had to frame correctly against the parapet stepping above them.

Delivered to tight deadlines and exacting measurements. The result demonstrates that Accumen®'s moulding systems suit modern commercial expression as readily as heritage restoration, Art Deco isn't heritage, it's contemporary architectural language with deep proportional rules.

Outcome

The BurgerFuel HQ has become a recognisable architectural moment on Great North Road, a building where the brand and the architecture reinforce each other. The illuminated insignia at night, framed by the stepped parapet, is the project's signature image.

The project sits in the portfolio as evidence that Accumen®'s systems deliver well outside the heritage residential context that's most associated with classical mouldings work.

Year

2014

Location

Britomart, Auckland

Architect

Cheshire Architects

Profiles

5 distinct

Key products used fourPLUS® ShapeCrete® Cornices Architrave Bands Dentils & Corbels Custom Mouldings

The brief

A majestic old building restored to its former glory. The Quay Building is a five-storey heritage commercial façade in the heart of Britomart, keystoned arches at ground level, pilaster capitals through the middle floors, full classical cornice at the top, and a base course running the length of the elevation.

Five distinct moulding profiles needed replication across the façade. The architectural specification called for visual fidelity to the original, modern composite substitutes that read as fakery weren't acceptable.

Our approach

Accumen® replicated the majority of the building's decorative mouldings, five distinct profiles spanning keystoned arches, pilaster capitals, cornices, and base details, to bring the façade back to life.

Each profile was developed from surviving fragments and from period photographic record. Where original elements still existed, they served as the master for replication; where they didn't, the architect's drawings and historical reference filled the gap. Every profile went through workshop sign-off before committing to full production.

Delivered alongside Cheshire Architects, Bracewell Construction for site management, and Andrew Plastering for the skilful installation of the decorative details. The plastering trade integration was particularly important, five distinct profiles installed across five storeys means the rhythm and alignment between trade scopes is everything.

Outcome

The Quay Building was returned to its former glory in 2014, a captivating commercial façade in the centre of Britomart, restored to a standard that won't date.

The project demonstrates Accumen®'s collaborative trade integration with leading NZ architects on serious heritage work. Cheshire Architects, Bracewell Construction, and Andrew Plastering all on a single restoration is the kind of team you build heritage projects with, not a generic supply chain.
