"Stackcell and its corresponding programming tool have significantly reduced on-site mistakes while accelerating construction, through an efficient production based philosophy."
What Trades and Suppliers are saying....
They know the system well !
“As an electrical and HVAC subcontractor, working with Stackcell and KIRSTEN automation gives us real confidence in project delivery. The clear visibility and coordination allow us to plan labour and materials well in advance, knowing work will be ready as scheduled. It’s a system that’s easy to adopt at all levels, from apprentices through to project managers.”
Josh Cross - Director
X Electrix Ltd
“KIRSTEN plays a pivotal role in our ability to plan and manage stone slabs months in advance.
We know with certainty when each unit will be ready so can manage our stock levels accordingly.
More importantly KIRSTEN helps us to coordinate our most valuable resource- our team.”
Benji Sharp - General manager

“Qualico construction is proud to be a build partner to stackcell projects, we are amazed at how efficient a concrete structure building can be, we have never experienced pouring a 3rd floor ,while 1st floor is fitting out at the same time. This actually shortens heaps of time in programme and making it way faster to finish the building comparing to other traditional builds.
Stackcell system definitely simplifies concrete structure building in every possible way. with KIRSTEN, it smooths every step and manages every pour months in advance. We NEVER MISSED a pour.
This innovation should be widely introduced, and should benefit the whole building industry"
Jason Li -General Manager
Qualico Construction ltd
“RG Reinforcing Ltd has been supplying pre-tied and loose reinforcing steel to Stackcell projects for over seven years, including NZ Living and Simplicity Living developments. The Stackcell system has consistently made our reinforcing work more efficient, accurate, and well coordinated. Their planning, communication, and commitment to quality make every project smoother. We value this long-term partnership and look forward to supporting many more Stackcell builds.”
Vicas Garg - Managing Director
RG Reinforcing ltd
“Connect has built hundreds of apartments using Stackcell and KIRSTEN. Stackcell starts the construction process and KIRSTEN delivers the productivity flow to all trades.
Gone are the days where trades are working on top of each other.
As a subcontractor of structural and carpentry labour, we have seen firsthand how Stackcell and KIRSTEN consistently complete projects on time and within budget..”
Craig Murphy – Managing Director Connect Construction
“Since 2018, I have had the privilege of working on brickwork alongside Brandon's project, starting with NZ Living, moving from traditional methods to timber framing and blockwork, and continuing to date with today's Stackcell/KRISTEN system. This evolution has boosted productivity and efficiency compared to projects still using traditional methods and systems, especially now with wider scaffolding for work and brick stacking. The benefits of Stackcell are clear compared to fixing brick ties and shelf angles directly to the concrete wall, as it offers better grip for fittings. Throughout the construction, we have followed the KRISTEN management system, which we are familiar with. The Stackcell/KRISTEN system benefits not only bricklayers but all trades, builders, and developers—particularly in a sector where time directly impacts costs.”
Teng Seng Hann – Manager
Epro Construction ltd
"Working as a interior team with the Stackcell system makes a big difference on site. The fire-rated concrete walls means no post-line inspection for fixing, allows us to go straight into plastering without delays.
This also shortens the time needed for stopping and painting — what would normally take over a month can be completed in around three weeks per level, while still achieving a high-quality finish."
Andrew Kim - Director
ANK Painting Services ltd
"Tray dec NZ is proud to be a trusted manufacturing partner and supplier of the Tray dec® Composite Steel Flooring System.

Why use Stackcell Structures?
Lets Face it!
A building with multiple structural elements is a slow and expensive one, with internal fit out taking longer than it should.
That's where Stackcell Stuctures comes in...
the system is insitu concrete walls and slabs.
Its like "building on steroids'" It not only drives the structure up super fast...
but also allows early fit out, due to the monolithic concrete walls and slabs.
Use Formulas.. not Programmes!
Its solid 30mpa concrete
Internal fit out can start very early!
THE STACKCELL SYSTEM IS THE SECRET TO YOUR DEVELOPMENT SUCCESS
It's the difference between the 10,000 developers that make ok returns,
to the 1% that make great returns
Without Stackcell Structure system
- 30% inefficiencies in structure build
- Longer durations on site- More P&G Spend
- Expensive
- Frustrating
- Sub-contractor variations
With the stackcell structure system
- Monolithic concrete structure - No Joints!
- Automates 50% of your Deliveries (if KIRSTEN Software used)
- Internal fit out can begin 50% quicker
- Cheap passive fire
- Weathertight during the Build
Do you like getting good returns on projects?
Then give Stackcell Structures a call!
Designed for Developers who want to change!
What is Stackcell permanent formwork made of?
The stackcell formwork comprises of an injection moulded plastic spacer ,which is sandwiched between two sheets of 9mm form-ply to form a module size 2820mm x600mm.
One complete module weighs 24kg and are made on your project, by the carpenters.
Lets call it "ON Site Manufacturing" The self compacting concrete is poured using a boom pump in a 3D printing fashion, by pouring the 1st layer up to 1m, and continuing with the 2 subsequent pours in the same day.
- Each module takes approximately 8 minutes to make.
- A Plasterboard screw gun is used ... yep, that's it !
- The 30mpa concrete mix is very fluid and forms a monolithic solid structure.
- The walls are Shear walls in nature, so are very good for seismic, as dense reinforcing can be used.
Concrete structure automation
A NEW construction formula” and concrete formwork system unveiled here are not just tools; they're catalysts for transformative change.
Prepare to reimagine your approach as you delve into a realm where innovation meets efficiency.
The narrative unfolds to reveal an automation revelation, a cornerstone of unprecedented efficiencies on construction sites.
This isn't just about construction...
it's about rewriting the narrative of possibility.
We embrace the basic fundamentals of insitu concrete design and implementation, weaving them into a seamless tapestry of consistent progress.
- No more multiple connection Details
- Solid concrete inter-tenacy walls
- The Structure cycles are automated - no phone calls to order concrete
- Monolithic Balconys - poured with main slab - No Joints!
Stackcell Structures
The bigger the project
The faster it goes!
How on earth do you automate concrete deliveries??
Because we use the Stackcell structure system!
By using a standardised layout of walls with simple reinforcing, on each floor, the build duration for each floor is guaranteed, which enables us to lock in concrete pours far in advance of industry norms. ( 4-6 months out)
KIRSTEN Automation explained 👇👇
WATCH NOW
What about rain!
We love the rain!
We pour in any weather, with the exception of those really bad days.
No Phone calls
no wasting time on phone booking in pours
No Emails
no wasting time on back and forth emails booking in pours
live feed
Concrete plant, Placers and concrete pump company have a live feed of upcoming pours .
They simply tick a box to confirm. Visible to all.
What else does the Stackcell system provide to your project?
The Stackcell system is a plug and play insitu concrete method,
using walls and slabs to create a homogeneous concrete skeleton,
which allows quicker internal fit out, due to the watertight nature of concrete.
Can the system do columns and Beams?
Yes it can!
Stackcell is multi use
Because Stackcell is a carpentry based formwork system, it is easily formed with walls/beams and columns.
- No Shopdrawings ... Your imagination is the limit!
- Lightweight... No heavy steel or aluminum formwork
- Any beam size ... any size up to 600mm is achievable
Previous project stats...
The stackcell structure system used for 2 level terrace, 3 storey and up to 12 storey apartments, has seen a reduction of up to 30% off normal construction costs.
see for yourself....
The average statistics from last 4 Projects !
- Average construction cost per apartment to build: $275k
- Average construction cost for a development: $2995/m2 (excl land, builders margin)
- Average structure cost to build : $778/m2 excl margin
- Average Build speed per apartment (taken from civils start to full completion) : 3.5 days per apartment
- Stackcell Wall system average cost : $295/m2 incl pump/reo/conc(excl margin)
What's all this Seismic stuff about?
Stiffer buildings could save billions in earthquake damage, researchers say
Stiffer Buildings explained 👇
- Less inter-story drift =safer Buildings
- Japan and Chile are 100 years ahead!
- Buildings that sway less during earthquakes, could dramatically reduce damage across New Zealand.
- Continued building functionality post-quake, as successfully implemented in nations like Japan and Chile for decades.

STILL GOT QUESTIONS?
We got you!
Frequently Asked Questions
What is your fire rating of walls?
As per AS1530.4-2014, section 3. Vertical separating elements- Loadbearing . a 140mm Stackcell wall achieves 240/240/240 (4hrs)
Ref test report: PF2424148
Can you actually automate concrete Deliveries?
Absolutely!
Its the same information you provide over the phone to dispatchers, we just simplified and automated it!
Is there a specific layout of walls that is cost effective?
Good Question! Yes, the optimal layout of walls is to provide 6m spans for the Traydec flooring, but we have done 6.5m spans and 7m spans.
It just means the slab thickness increases from 180mm to 200mm and 260mm. Keep the walls on all floors the same for optimal structural design.
For optimal cost advantage, the walls should line up vertically through the upper floors to reduce any transfer structure loads.
Do you need to take the exterior formply off?
Yes, the exterior facade formply gets taken off to comply with the "no combustibles in the cavity rules".
The internal Formply remains on, but could be taken off if required, and walls skimmed with plaster.
Do you need to apply a sealer coat or wrap to the exterior face of concrete?
No, because it is 30mpa concrete and by using our self compacting mix, it is very dense. More dense in fact than traditional concrete.
This is the reason, the internal fitout can begin without the external cladding being complete yet. We are seeing crush test results of 46mpa at 28 days.
Can you just sell us the wall system materials for our project?
Yes, absolutely! We offer a supply only option for your own carpenters to use and install the walls.
We give you a quick show and tell and you are off!
Is it cheaper than Blockwork?
About 15-20% cheaper than blockwork! You see, blockwork requires heavy scaffold internally, lots of different types of reinforcing, cutting saws, trained blocklayers, waste bins, water etc.
Can you really build an apartment in 3.6 days?
Yep! .....The formula is this.
start on site date - completion date (working days)/number of apartments
Its a Volume metric. The larger the development, the faster it goes.
Could you show our team how to implement the KIRSTEN Programme method?
Yes, absolutely! It is a free service when you use the Stackcell structure system on your project.
We advise your project manager or site team on how to use it, set you up with it. The great part is, once you use it once, you will wonder why the heck you didn't do it sooner!
Can we use you for just the walls and not the full structure?
Yes, you can for sure! But the automation features fall away and it becomes more expensive.
Its kinda like taking 4 of the 8 ingredients out of a chocolate cake recipe, and instead of following the recipe ,you make your own. Both cakes taste good, one just costs more! and takes longer!
We would prefer to offer you a supply only option then for the site teams to control.
Can i use Flat slab, Rib and infill type flooring?
Yes, you can. However, we have found these to be 20-30% more expensive than Traydec ,because of the shopdrawing process/design, double handling of flat slabs/beams .
If you think about it, why would you pour a flat slab in a factory miles away from your site, transport it on large trucks, sort it on site, double prop the slab, and then.....Pour it again! with a topping slab.
We recommend Traydec for ease and cost effective builds as seen across the last 1000 apartments already.
Can the system do columns and beams?
Yes, columns and beams can be done with Stackcell. We use 18mm formply and plastic extrusions to match, to form these.
