Three-storied houses could be more common in Auckland under a new housing policy supported by both Labour and National.

The new policy, which was announced earlier this week, enables people to build up to three homes of three storeys on most sites without any need for resource consent, starting August twenty twenty three.

Analysis from consultants PWC told the government these changes would add between 48,200 and 105,500 new dwellings over the next five to eight years.

Professor John Tookey is a professor in construction management in AUT, and he said while the new policy is a significant step forward the devil is in the details.
