How much does it cost to build a house in Australia?
A straight-talking national picture for 2026 - what you'll pay per square metre, what real homes cost, and the site costs that catch people out. Then we point you to live, state-specific prices so the number is real for your block.
Build cost per square metre
Most new homes in Australia fall into one of three bands. These are national construction-only ranges (excluding land) - your state, builder and block move you within them.
Volume / project home
Standard inclusions, repeatable designs, the most affordable way to build new.
Custom home
Bespoke design, upgraded finishes, more site-specific engineering.
Architect / high-end
Full architectural service, premium materials, complex or sloping sites.
What a whole home costs
Townhouse / small lot (~150m²)
$300k - $480k
4-bed single storey (~220m²)
$420k - $720k
Double-storey family home (~300m²)
$620k - $1.1m+
Construction only, national averages for 2026. Land is separate and varies enormously by city and suburb.
The costs people forget
- Site costs (soil, slope, retaining): $20k - $90k+
- Demolition for a knockdown rebuild: $25k - $45k
- Driveways, landscaping, fencing: $15k - $60k
- Council, planning and connection fees: $5k - $20k
