NZ's hidden homes

14 December 2017: New research offers practical, community-based solutions to New Zealand? ?!"s housing crisis by turning existing stock into far more affordable, fit-for-purpose homes.

A new report from the Building Better Homes, Towns and Cities National Science Challenge shows around 12% of New Zealand? ?!"s housing stock is significantly under-utilised and many houses could be partitioned to deliver up to 180,000 new dwellings.

The ADU Potential report suggests that the Auckland region has a potential 45,000 partitionable dwellings. Meanwhile, at the other end of the scale, Marlborough has around 2,000 partitionable dwellings. These dwellings would not impinge on greenfield sites or unutilised vacant land. There is also opportunity to introduce other forms of accessory dwellings (ADUs).


Land costs and affordability

4 December 2017: It has become taken for granted that the cost of housing is driven by land prices. Certainly, the land price is generally the biggest ticket item in the cost structure of a new build.

Builders and developers say the cost of land is a major barrier to building dwellings that low-income and middle-income households can afford. A National Science Challenge project is looking at what drives land prices.


Investing in affordable homes

1 December 2017: While central and local government are encouraging new builds and the release of land for residential purposes, high numbers of residential new builds are not affordable housing for those with limited resources.

Up to the 1980s, New Zealand enjoyed a steady supply of affordable housing, but now there is a serious shortage in many centres. A National Science Challenge project seeks new ways to address this issue.


Decoding housing messages

1 December 2017: In the 2017 election year, housing has been a hot-button issue with politicians, broader government and the public. What is it about these overarching themes of social justice and wellbeing that capture our attention? By looking at how politicians have defined New Zealand? ?!"s housing problems, particularly supply and affordability, researchers hope to better understand how diverse messages are translated into policy and practice.
