Estimated building costs
The Department provides estimated building costs to help territorial authorities estimate realistic values when they consider the job value provided with a building consent application.
The table below shows the latest figures for various building types by region.
Guide to the table
Costing information is provided by construction cost consultants Maltby and Partners Ltd.
The costs are for one-off speculative houses. These figures do not reflect the economies from building group houses, or the additional costs normally associated with architecturally designed houses. Group houses are on average 21 percent cheaper and architecturally designed houses 20 percent more expensive.

The estimated unit construction costs are based on current commercial prices of materials and labour, plus allowances for contractors' overheads and margins. Pricing is based on a model building for each region.
We provide unit construction costs to help territorial authorities assess building consentfees. They are not intended as a definitive cost for actual buildings and should not be used for this purpose.
