Versatility
One System. Four Applications.
Deck is a structural floor platform. The same kit performs as an entertaining deck, a level floor over a failing slab, a landing at a doorway or a load-rated platform under a spa. One engineered system, adapted by where you put it.
Decks
Outdoor living at ground level. A sub 100 mm build height keeps the threshold at your back door exactly where it is, with no step and no ramp.
Floors
A dead flat floor over an uneven slab, garage, shed or studio. Adjustable pedestals absorb the fall without a screed, a grinder or a cure time.
Landings
Entries, back steps and door thresholds. Small footprint, level within minutes, and no formwork, concrete or waiting.
Platforms
Spas, tanks, cabins and marquees. Rated to 4.0 kPa, bolted together into any rectangle, and unbolted again when the site changes.

Engineering
Designed to Assemble, Not to Build.
A single extruded aluminium section performs as both bearer and joist. Every fixing point is drilled in the factory against the same jig, so the holes align, the spacing is decided and the geometry cannot be got wrong on site. The result is a deck that is assembled rather than built.
Precision Pre-Drilled
Every beam, bracket and board is cut, punched, drilled and labelled before it ships. No saw on site. No pilot holes. No measuring twice. The parts fit one way only.
Assembly in an Afternoon
Four to eight hours, depending on size and hands. One person is enough. Two is faster. A cordless drill is the only power tool required.
Single Person Handling
Under 3 kg per metre. A full length bearer carries over one shoulder. Nothing on the pallet needs a second set of hands to lift.
Immune by Material
Aluminium does not rot, rust, burn or feed termites. It will not cup, split or twist, and it never needs a coat of anything.
Lifetime Structure
Aluminium oxidises once and then stops. The frame has no service life in the way timber does. Replace the boards in twenty years if you want to. The structure underneath stays.
Sub 100 mm Profile
Full 4.0 kPa capacity inside 100 mm of build height. Doorways stay level, steps stay compliant, and no ramp is needed at the threshold.
Certified, Not Asserted
Designed to AS 1170 and AS 1664.1, with span tables published in full and a four-point bend test to 24.02 kN peak load.
Infinitely Tileable
Kits bolt to kits along a shared edge. Three standard footprints combine into any rectangle without a custom order or a custom price.
Fully Reversible
Bolted, never glued or nailed. Lift it, relocate it, or take it with you. Aluminium holds scrap value at the end of its life.
Configurations
Three Sizes. One System.
Medium
3.0 × 1.8 m
- Area5.40 m²
- Joists8 × 1.745 m
- Bearers2 × 3.0 m
- Brackets4 edge / 12 centre
- Screws128
Large
3.0 × 3.0 m
- Area9.00 m²
- Joists16 × 1.445 m
- Bearers3 × 3.0 m
- Brackets8 edge / 24 centre
- Screws256
Every configuration ships complete, boards, clips and trim included. Footprints are fixed so that parts remain identical and cost stays down. A 6 × 3 m deck is two Large kits, sharing an edge and bolted together.
Structure
The Frame Outlasts Everything Above It.
Bearers run the long axis onto adjustable pedestals. Joists seat into brackets that fix the 450 mm spacing without a tape measure. Count the holes in the images below. Every one is drilled to jig before the beam leaves the factory.
Small
2.4 × 1.2 m
2 bearers, 7 joists, 4 bays
Medium
3.0 × 1.8 m
2 bearers, 8 joists, centre bearer
Large
3.0 × 3.0 m
3 bearers, 16 joists, three bays
450 mm
Maximum joist spacing. Bracket positions are pre-drilled, so the spacing is set before you open the pack.
2000 mm
Maximum single joist span between bearers. Add a bearer beyond that point and the span resets.
900 mm
Maximum spacing between stumps or footings beneath a bearer.
55 × 45 mm
A single extrusion serving as both bearer and joist. Central web vertical, with orientation marked on the part.
Installation
A Deck, Start to Finish.
The complete installation, bracket by bracket and board by board, with nothing edited out. Six minutes to watch. One afternoon to do.

Before You Build
Check Your Council First.
Terraform Deck sits under 100 mm off the ground, which in most states is well below the height at which a deck starts needing a building permit. That is not a promise. Thresholds, setbacks, floor area limits, overlays and bushfire rules all vary, and your local council has the final say.
Start with your state or territory below, then confirm with the council that covers your address. It is the installer’s responsibility to meet local codes and obtain any permits. Footings should be designed and certified by a civil engineer.

Questions
How long does it take to build?
Four to eight hours, depending on the size and how many people are on it. One person can build a Small on their own. Two is quicker and more comfortable for the Large.
Do I need a builder?
No. Every part is pre-cut, pre-drilled and labelled, and the kit ships with printed instructions. Call it five out of ten for difficulty. If you would rather not, any builder will have it done in half a day.
Are the beams really all pre-drilled?
Yes, every one. Bearers, joists and brackets are drilled in the factory to the same jig, so the holes line up and the joist spacing is already set. You do not drill a pilot hole anywhere in the build.
What tools do I need?
An 18 V drill, a hammer, a tape measure, gloves, and eye and ear protection. Nothing else. No saw, because nothing needs cutting.
Will it hold an outdoor setting?
Yes. The frame is designed to a 4.0 kPa live load, roughly 400 kg per square metre. In test it held 1800 kg over 2 m² for ten minutes.
How long will it last?
The aluminium frame lasts a lifetime. It does not rot, rust, warp or feed anything, and aluminium forms its own oxide layer and then stops. The warranty is ten years because that is a warranty, not a use-by date. Boards are a wear item and can be replaced without touching the frame.
Do I need a permit?
Usually not at this height, but it depends on your council, the location and what is around it. Start with the state links above and confirm with your council. It is the installer’s responsibility to meet local codes and get any permits, and footings should be designed and certified by a civil engineer.
Can I get a custom size?
No, and that is deliberate. Fixed sizes are what keep the parts identical and the price down. The three footprints bolt together, so a 6 × 3 m deck is two Larges and a 4.8 × 1.2 m is two Smalls.
Which boards come with it?
Composite boards with recycled content, cut to length, with the clips and edge trim to fix them. They come in the pack. If you would rather lay your own hardwood, the bracket spacing suits standard board fixings.
How does it handle weather?
Aluminium does not rot, warp or feed termites, and it will not carry flame. Near salt water, expect the screws and brackets to age faster than the beams. That is normal for any fixing near the coast.
Can it go against steel?
Only if the steel is galvanised or powder coated. Bare steel against aluminium corrodes. Every screw in the kit is galvanised for that reason.
