The kit price you see advertised is just the materials delivered. A realistic total is often 1.5 to 2 times the kit price once you add the slab, assembly labour, plumbing, electrical, services and approvals.
Ways to save
- Read what the kit actually includes, many exclude the slab, wet areas, plumbing and electrical entirely.
- Owner-building saves the builder margin but needs a permit, time and the discipline to manage trades.
- Get a true all-in figure, kit plus site plus services plus approval, before comparing a kit home to a conventional build.
How we estimate this
A kit home in Australia typically costs around $45,000 to $160,000 for the kit alone in 2026 depending on size, but the finished, approved, connected home usually costs 1.5 to 2 times that once slab, assembly, services and approvals are added.

What a kit home costs in Perth
A kit home in Perth is priced on three parts: the kit of pre-cut, flat-packed shell materials, the labour to assemble it, and the site works, footings and service connections the kit price leaves out. The kit is only the frame, cladding and roof, so the assembly, the slab or footings, and connecting power, water and sewer are substantial extras, which is the thing most buyers underestimate about a kit home.
Perth's sandy, stable soils are an advantage, because the firm, free-draining ground gives good, straightforward footings for the kit without the engineered footings a reactive-clay site needs, keeping the site works simpler. A kit home is usually a rural, Perth Hills or lifestyle-block choice, often a lighter steel or timber-framed kit rather than the dominant double-brick, so it is a departure from the local norm. The hot, dry Mediterranean summer means the kit needs insulation to stay cool. The isolation of the WA market can add freight and lead time to a kit delivered from the eastern states, a real cost here. The owner-builder saving depends on the assembly, and the home must meet the code and gain approval.
A kit home is a dwelling that must meet the building code, so assembly is done by a licensed builder, or by an owner-builder with an owner-builder permit for suitable work, with building approval, in Western Australia under WA Building Services, and licensed plumbers and electricians for the services. For a Perth block, the clearest way to price a kit home is the kit plus the assembly plus the site works and services, with sandy soils easing the footings and WA freight a factor.
