Interest.co.nz's latest analysis of residential building consents suggests a gathering storm in the residential construction sector.
Statistics NZ's building consent data shows that just 9719 new dwellings were consented in the first quarter of this year, which was down 21.2% compared to the first quarter of last year. It was the first time that the number of new dwellings consented in any quarter of the year has been below 10,000 since the second quarter (Q2) of 2020.
That suggests a major downturn in residential building activity is on the way as new projects are completed.
At the same time high inflationary pressures within the industry continue to impact projected building costs.
The average size of new dwellings consented over the last year has barely changed, from 146 square metres (sqm) in Q1 2022 to 143sqm in Q1 this year. The average estimated build cost per sqm has increased by 14.7% over the same period, from $2695 per sqm in Q1 2022 to $3091 per sqm in Q1 2023, which was the first time ever that it has been above $3000 per sqm.
That pushed the estimated average construction cost per dwelling, excluding land, up 11.7% from $394,554 in Q1 2022 to $440,706 in Q1 2023.
However, even though average building costs continue to increase, the decline in the volume of building work being consented means forward projections of the value of residential building work are also showing a significant decline.
In the fourth quarter of last year, the estimated build costs of all new dwellings consented was down just 4.3% compared to a year earlier, but in the first quarter of this year, total estimated build costs were down 12% compared to a year earlier, even though building cost inflation was running at 14.7% pa.
The biggest downturn in consent numbers has been for standalone houses.
In the first quarter of this year consents were issued for 3956 new standalone houses.
That was the first time in exactly 10 years that quarterly consent issuance (in any quarter of the year) for standalone houses has been below 4000. It was down by 30.5% compared to the first quarter of last year.
Consents for new apartments and townhouses/home units were also down, by 15.9% and 21.1% respectively compared to a year earlier, while retirement village units were the only dwelling type to still be showing consistent growth, up 60% in Q1 2023 compared to the same period of last year.
A regional breakdown of new dwelling consent trends in the main population centres of Auckland, Waikato, Bay of Plenty, Wellington, Canterbury, Otago and nationally, which shows the quarterly movements in new dwelling consent numbers by dwelling type, as well their average build cost per square metre going back to 2010, is available on our Residential Building Consent Analysis page.
