How much is a 4-bedroom kit home?

In Australia, a typical 4-bedroom kit home costs around $360,000 in total, depending on your location, design, and level of finish. As a general guide, about half of that cost roughly $180,000 goes toward materials, while the other half covers labour and construction if you engage builders and trades.

If you have an owner-builder permit and are confident managing your own project, you can save substantially by doing some of the coordination and basic work yourself. Many iBuild clients who act as their own project managers have reported saving 20-40% compared with a full builder-managed home.

Here’s a breakdown to give you an idea of where the money goes:

Kit materials (approx. $180,000): includes wall and roof framing, cladding, roofing, insulation, windows, doors, linings, fixings, and other supplied components.
Labour and trade costs (approx. $180,000): covers carpenters, plumbers, electricians, tilers, and other licensed trades needed to complete the home.
Site and approval costs: vary by council area and site conditions (e.g., soil tests, BAL ratings, planning permits, foundations).
Optional upgrades: like premium finishes, higher energy ratings, verandahs, or garages can influence the total price.

For comparison, a conventional 4-bedroom home built by a volume builder often exceeds $500,000–$600,000 once builder margins, overheads, and extras are included — making kit homes a cost-effective alternative for those who prefer flexibility, hands-on involvement, and long-term value.
