What does it actually cost per square metre to build in NSW right now?
A straight answer to the number every owner-builder asks first — the real range, where it comes from, and the one thing to actually watch for in this market.
- 01
A standard, mid-style home in NSW is currently running $2,100–$3,200 per square metre.
That's a fairly standard spec — no major custom design work, standard finishes throughout. It's the number to start a budget from, not the number to hold a builder to without a written quote.

A more custom build can reach $2,500–$4,500 per square metre.
Complex design, higher-spec finishes, and difficult sites (slope, access, bushfire or flood overlays) push the rate up fast — the same floor area can cost twice as much depending on what's actually being built.

Cordell's published construction cost rates sit between $1,700 and $4,500 per square metre — a wide band, and wide for a reason.
Cordell is an independent Australian construction cost data provider used across the industry for benchmarking build costs, not a builder's marketing number. Even an independent, data-driven source spans a huge range once site conditions and spec are factored in.

Be careful of anyone quoting well under this range in the current market.
A price that's meaningfully cheaper than everyone else's isn't automatically a bargain — it's usually missing scope you'll meet later as a variation, or corners cut somewhere you can't see yet.

A square-metre rate is a sanity check, not a quote.
Use it to tell whether a quote is in the right universe — then get an itemized, apples-to-apples comparison before you commit to anyone.
If you only remember one thing
A square-metre rate tells you if a number is roughly sane. It doesn't tell you what your build will actually cost — only an itemized quote against your actual scope does that. Run every quote through the Quote Comparison sheet before you sign anything.
Rates current as of September 2026 — construction costs move with the market, so treat these as a starting benchmark, not this month's fixed price.
