New Government Rules Make it Easier to Build 70m² Minor Dwellings – Here’s What You Need to Know
New Zealand’s updated planning rules have made it significantly easier for homeowners to build 70m² minor dwellings and granny flats on their properties—offering a flexible and affordable way to add value. These changes are opening new doors for homeowners across the country who want to make the most of their land.
At Origin Architecture, we specialise in small home design, and we’re proud to offer two architecturally designed solutions that fit within the new guidelines: the Origin 70m² Minor Dwelling and the Low-Energy SIP Panel 70m² floor plan. Both options offer smart, efficient layouts and modern design, tailored to New Zealand lifestyles.
What Are the New 70m² Building Rules in NZ?
Under the updated regulations, minor dwellings up to 70 square metres can now be built without resource consent in many parts of New Zealand, as long as they meet basic planning controls such as setbacks and height limits.
This rule change means it’s now easier than ever to:
Add a granny flat for extended family
Create a home office or guest house
Invest in a small rental property for passive income
Downsize while remaining on your own land
These minor dwellings offer flexibility, affordability, and long-term value, especially when designed to a high standard.
