The 70m² Granny Flat Rules Are Changing in 2026
Build without a building consent — but only if you meet the strict LBP and compliance requirements.
What the 2026 rule change really means
From early 2026, homeowners may be able to build a self-contained granny flat up to 70m² without a building consent. While this removes a major barrier and help reduce costs, the process still requires licensed professionals, council notification, and full compliance with the Building Code.
Our role is to simplify this entire journey — handling the planning, paperwork, and build so you can focus on the outcome, not the process.
What you’ll learn in the checklist
How the 70m² “net floor area” rule actually works
Site and boundary rules most people miss
Why DIY builds aren’t allowed

How to plan now so you’re ready in early 2026
If you’re going to build small, build nice
Designing within 70m² means every decision matters. From layout and light to materials and compliance, thoughtful planning makes the difference between a small space that simply fits — and one that genuinely works.
We design and build granny flats that are carefully considered, fully compliant, and made to be lived in.
Built by licensed professionals. Designed to be simple.
