Short answer

Building a new house in Sydney in 2026 costs about A$2,000–A$2,800 per m² for a project home, A$2,600–A$3,800 for custom mid-range, A$3,430–A$5,500 for premium and A$4,500–A$6,500+ for luxury or architectural design, for construction alone [3] [2] [1] [4] [6] [7]. That puts a 250 m² home at roughly A$500,000–A$950,000 at project to mid-range rates, before site works, design, approvals, services, external works and fees. In AUD Build’s calculator, a 220 m² project home on a level Western Sydney block comes to about A$509k–A$824k all-in and a 300 m² premium home on a difficult North Shore block to about A$1.51m–A$2.14m, excluding land. For comparison, the average value of a new house approved in Greater Sydney in 2025–26 was about A$595,000 [10].

Cost per m² by specification

Specification	Published range per m² (construction only)	Sources
Project or volume builder	A$2,000–A$2,800	Struqt and Rawlinsons/RLB via MNA from A$2,000; CPP QS project homes A$2,400–A$2,800 [3] [2] [1]
Custom mid-range	A$2,600–A$3,800	Rawlinsons/RLB via MNA A$2,600–A$3,500; CPP QS custom A$3,000–A$3,800 [2] [1]
High or premium	A$3,430–A$5,500	Buildana high spec from A$3,430; Pearson premium custom on the North Shore to A$5,500 [4] [6]
Luxury or architectural	A$4,500–A$6,500+	CPP QS architectural from A$4,500 (and above A$10,000); Pearson premium custom A$5,000–A$6,500 [1] [7]

Sources define the tiers differently, so the bands overlap. Pearson prices habitable floor area; other guides do not say whether garages and alfrescos are counted, so compare quotes on the same drawings and the same floor-area definition [6].

What a 200–300 m² home costs

Source	Home	Published range (construction, excluding land)
CPP QS [1]	200 m²	Project A$480k–560k; custom A$600k–760k; architectural A$900k–A$2.0m+
Struqt [3]	220 m², volume builder	A$440k–704k (rate × area only)
MNA, Rawlinsons/RLB [2]	200–250 m², four bedrooms	Custom mid-range A$520k–875k; architectural A$760k–A$1.08m+
Buildana, Western Sydney [5]	250 m², four bedrooms, vacant land	A$550k–750k
Jonathan Homes, RLB [8]	250 m² custom	Standard A$700k–875k; mid-range A$875k–A$1.25m
Pearson, Hills and North Shore [7]	250 m² custom	Builder standard A$875k–A$1.0m; mid-range A$1.0m–A$1.25m

Official averages

The average value of a new house approved in NSW in the 12 months to August 2026 was about A$569,840, and in Greater Sydney in 2025–26 about A$595,485 (14,164 houses); AUD Build divided the ABS value by the number of houses [10].
ABS approval values should exclude land, demolition and landscaping but include site preparation; for most project homes they are the contract price [11].
New detached houses completed in NSW in 2024–25 averaged A$565,749 to build, or about A$2,396 per m² on an average 236.1 m², according to Master Builders NSW from ABS data [12].
These averages are mostly project homes, which is why they sit at the low end of the builder ranges above.

Costs on top of construction

The NSW Government lists a site survey, BASIX certificate, DA fees if you need a DA, a construction certificate and possible infrastructure contributions as approval-stage costs, and caps the deposit at 10% [13].

Cost	Typical range	What to know
Site works	Level A$5k–20k; sloping A$20k–100k+	Cut, fill and retaining; Pearson puts sloping Turramurra, Wahroonga and Hornsby blocks at A$40k–100k+ [5] [7] [3]
Service connections	A$10k–40k	Water, sewer, power, gas, NBN and stormwater, itemised by Buildana [5]
Survey, geotechnical, BASIX, structural	A$8k–14k	Pearson puts the consultant bundle for a custom home at A$12k–30k [4] [7]
Design and documentation	A$12k–40k; architect A$30k–100k+	Buildana also gives 5–10% of construction [28] [7] [5]
Approval	CDC A$3k–9k; DA A$5k–18k	The council DA fee itself is about A$2,748 on a A$700,000 home and A$3,240 on A$1 million [28] [14]
Council contributions	A$0 to A$30k+	Depends on the council plan; most s7.11 plans are capped at A$20,000 or A$30,000 per dwelling and s7.12 levies are usually up to 1% [15] [2]
Housing and Productivity Contribution	Not charged	It applies to subdivision and to medium- or high-density housing such as dual occupancy, not to one house on an existing lot [16] [17]
Sydney Water	Building plan approval	A Section 73 certificate is usually not needed on lots created after April 1964 [18] [19]
Long service levy	0.25% of works of A$250,000+	About A$1,750 on A$700,000, paid before work starts [20]
HBC insurance	Base 1.158% of the contract	About A$8,100 on A$700,000 before the builder’s loading or discount; compulsory over A$20,000 [21] [22]
External works	A$25k–90k	Driveway, fencing and landscaping, usually outside the build price [2] [4] [28]
Contingency	5–15%	Builders publish 5–20%; keep it separate from the quote [28] [5] [3]

What moves the price

Slope. Split levels, stepped footings and suspended slabs add structural work; Pearson says an irregular or sloping block adds 10–25% to the build [25] [7].
Soil and rock. Reactive clay needs deeper engineered footings; rock has to be broken or excavated. Get a geotechnical report before you budget [5] [3].
Bushfire. Building on mapped bush fire prone land must address bush fire protection; Pearson puts BAL-12.5 to BAL-FZ upgrades at A$15,000–A$70,000 [24] [7].
Flood. Raised floors and flood-proofing add about A$15,000–A$40,000 [5].
All site factors together can move a budget by 20–40% against a flat, standard block of the same size [1].
Finishes. Moving from project-home to custom mid-range specification adds about A$400–A$1,100 per m²; a builder-grade and a custom joinery kitchen in the same footprint can differ by A$30,000–A$80,000 [2] [1].
Location. Inner-ring and eastern suburbs usually cost more than outer and Western Sydney; North Shore builders quote A$3,200–A$5,500 per m² [1] [6].
Energy rules. New homes must meet BASIX, including an average of 7 NatHERS stars since 1 October 2023 [23].

How long it takes

New houses in NSW took an average of about 11.6 months from approval to completion in 2025–26: about 2.6 months to start and 9.0 months to build (ABS quarters converted to months) [26]. Before that, a complying development certificate can be issued in as little as 20 days, while a DA averages 70 days [27]. Builders publish about 8–14 months from design to handover for a custom home on vacant land [5]; see the knockdown rebuild timeline for council-by-council approval times [29].

If there is already a house on the block

Add demolition (usually A$10,000–A$40,000 before asbestos), asbestos removal and rent while you build; the knockdown rebuild cost guide and calculator cover these [28]. Not sure whether to rebuild at all? Compare the options in renovate or knock down and rebuild.

About A$595,000 per new house approved in Greater Sydney in 2025–26 (ABS value divided by number), and about A$569,840 across NSW in the 12 months to August 2026. These values exclude land and are mostly project homes.

What costs are not included in a builder’s per-m² rate?

Usually site works, service connections, design, surveys and engineering, approvals, council contributions, the long service levy, HBC insurance, external works such as the driveway, fencing and landscaping, and contingency. Ask each builder for a written list.

Do I pay the Housing and Productivity Contribution on a new house?

Not for a single new house on an existing lot. It applies to residential subdivision and to medium- or high-density development such as dual occupancy.

How long does it take to build a house in NSW?

About 11.6 months on average from approval to completion for new houses in 2025–26 (ABS), plus design and approval time before that.

Is it cheaper to build in Western Sydney than on the North Shore?

Usually. Western Sydney builder rates start around A$2,000 per m², while North Shore builders quote about A$3,200–A$5,500 per m², mostly because of sloping, constrained sites and higher specifications.
