Residential construction costs appear to be flattening out after a period of strong growth, potentially signalling the end of high cost growth in the building sector.
Interest.co.nz's Residential Building Consent Analysis Tables track the average build cost per square metre from all residential building consents issued throughout New Zealand.
These show average estimated build costs for new homes (excluding land), remained relatively flat at around $2350 per square metre throughout 2020, and then started rising steadily in the first quarter of 2021, peaking at $3124 per square metre in the second quarter of this year.
That puts estimated build costs in the second quarter of this year up 12.7% compared to the second quarter of last year and up 27.3% compared to the second quarter of 2021.
However although costs were still rising in the second quarter of this year, the rate of increase had slowed significantly, increasing by just $33 a square metre (1.1%) between the first and second quarters of this year. The graph below shows the quarterly trend.
The tables also break down build costs by dwelling types and this showed the estimated build costs for stand alone houses and apartments declined in the second quarter of this year, while costs for townhouses/home units and retirement village units continued to increase.
The estimated build costs for houses peaked at $3075 in the first quarter of this year, and then declined by $63 to $3012 in the second quarter (-2.0%).
Apartment build costs tend to be much more volatile which makes their trends less obvious, but they peaked at $5408 per square metre in the second quarter of last year and had retreated to $4444 (-17.8%) in the second quarter of this year.
Estimated build costs for townhouses and home units peaked at $3083 per square metre in the second quarter of this year, up 8.0% on the first quarter and up 17.0% on the second quarter of last year.
Retirement village units showed the biggest cost surge, peaking at $3611 per square metre in the second quarter of this year, which was up 27.9% on the first quarter of this year, and up a whopping 54.7% on the second quarter of last year.
The tables also break down building consent cost estimates by dwelling type nationally and for each of the main urban centres of Auckland, Waikato, Bay of Plenty, Wellington Canterbury and Otago - the tables can be accessed on our Residential Building Consent Analysis page.
