Prices shown include GST and are for the certified steel frame structure kit only — wall frames, roof trusses, subfloor system, site-specific engineering and council permit drawings. They exclude cladding, roofing, windows, doors, internal fit-out, delivery, slab and footings, site works and trade labour. Final price varies with design, size, site conditions and the BAL and wind ratings for your block. Contact us for a written quote.

Bring a plan, a sketch, or nothing at all.

Every BRIbuild building is designed for the block it will stand on. Where you start is up to you — the finish is the same: engineered, certified and council ready.

Start from a design

Choose a floor plan and change what you need — move walls, resize rooms, flip the layout. It stops being a standard plan the moment you do.

Bring your own design

Already have architectural drawings or a concept from someone else? Send them through and we will convert the design to light gauge steel and engineer it for your site.

Upload your design

Start from a sketch

A drawing on paper, a photo you liked, or a rough idea. We draft it properly to your block's orientation, slope, setbacks and BAL rating.

What is actually in the kit.

BRIbuild supplies the certified steel frame structure. That is the engineered skeleton of the building plus the documentation to get it approved. Cladding, roofing, windows, doors and internal fit-out are not included, which keeps the kit price down and lets you source those locally or through your own trades.

Steel is the most recycled material on earth.

Light gauge steel framing is manufactured to precise lengths off site, which means offcuts and site waste are dramatically reduced compared with conventional construction. What waste there is gets recycled rather than landfilled.

Termite proof without chemicalsNo chemical soil treatments or timber preservatives required.
Dimensionally stableSteel does not shrink, warp or twist, so the building stays true over decades.
Minimal site wasteComponents cut to length off site, offcuts fully recyclable.
