Build cost per square metre in NZ: a rough guide
Build cost per square metre is one of the most searched topics for anyone planning a new home in New Zealand — and one of the most misleading. Here's why a per-sqm figure is only a starting point, and how factory-built pricing gives you a clearer picture.
Why cost per square metre is a rough guide
A cost-per-square-metre figure sounds precise, but it rarely tells the whole story. Two homes with identical floor areas can have very different total costs depending on:
- Site conditions — a flat urban section costs less than a sloping rural site.
- Access — difficult truck and crane access adds to delivery and site-work costs.
- Foundations and services — piles, power, water and sewer connections vary hugely by location.
- Finishes and materials — premium fittings can dramatically change the per-sqm rate.
- What's included — some quotes cover only the building; others include transport, foundations and finishing.
The only way to know the real cost is to get a price for your specific site and design.
How prefab pricing compares
Factory-built homes are quoted as a complete price rather than a rate per square metre. We quote three ways, all inc GST, so you can see exactly what is and isn't included — rather than having site works, transport and finishing hidden inside a per-sqm rate.
Home price — ex factory
The completed building, priced at our yard. Inc GST. This is the most direct comparison to a per-sqm build cost for the building itself.
Delivered to site
The home plus transport and craning onto your prepared foundations. Inc GST. Adds the delivery cost that per-sqm figures usually exclude.
Turn key (excluding local services)
Delivered, set down, joined and finished ready to move into. Inc GST. This is the true total cost — the number to compare against a full build quote.
Don't compare a supply price alone
A kitset supply price can look low because it usually excludes labour, foundations and fit-out. Comparing it to a prefab turnkey price is not apples-to-apples. To compare fairly, work out the total cost to a finished, liveable home.

- What is the average build cost per square metre in New Zealand?
- Build costs per square metre vary widely depending on the type of home, materials, site conditions, location and what is included. Published cost-per-sqm figures are a rough guide only — they rarely account for foundations, services, site works or transport, which can add significantly to the total.
- Why is cost per square metre a rough guide?
- Two homes with the same floor area can have very different costs. A flat urban section with easy access costs less to build on than a sloping rural site. A compact home with simple finishes costs less per square metre than a large home with premium materials. The only way to know the real cost is to get a price for your specific site and design.
- How does prefab pricing compare to cost per square metre?
- Factory-built homes are quoted as a complete price rather than a rate per square metre. We quote three ways, all inc GST: home price ex factory, delivered to site, and turn key excluding local services. This makes it clear exactly what is and isn't included, rather than hiding site works and transport in a per-sqm rate.
- What is included in prefab pricing?
- Our ex factory price covers the completed building. Delivered to site adds transport and craning. Turn key adds foundations, site works and finishing — everything except local service connections (power, water, sewer at the boundary). All prices are inc GST.
- Why is comparing a kitset supply price misleading?
- A kitset supply price usually excludes labour, foundations, fit-out and finishing. Comparing it to a prefab turnkey price is not apples-to-apples. To compare fairly, work out the total cost to a finished, liveable home — including all labour and site work.
