Short answer: $2,000 to $5,500+ per square metre in Sydney. A typical 250sqm mid-range home costs $750,000 – $950,000 to build (excluding land). Sydney is 10-20% more expensive than Melbourne due to higher labour costs.
Sydney has the highest building costs of any Australian city. Labour is more expensive, logistics are harder, and council requirements are stricter — especially in established suburbs. But the financial incentives (FHOG + stamp duty savings) can offset much of this.

Frequently Asked Questions
How much does it cost to build a 4-bedroom house in Sydney?
A standard 4-bedroom home (220-280sqm) costs $550K – $1.1M to build in Sydney in 2026, depending on finish level. Mid-range: $750K – $950K. Excludes land.
Is it cheaper to build or buy in Sydney?
In western growth corridors (Marsden Park, Oran Park), building is often cheaper due to stamp duty savings and FHOG. In established suburbs, the land cost alone often makes building more expensive overall.
Why is Sydney more expensive than Melbourne?
Higher labour rates (5-15% premium), more complex council requirements, harder logistics (traffic, site access), and stronger union presence in construction. Materials are similar in cost.

NSW offers a $10,000 FHOG for new homes up to $600,000 (house and land) or $750,000 (new build only). Plus full stamp duty exemption up to $800,000. See our NSW FHOG guide.
