From 2026, new national rules will make it easier and more affordable to add a minor dwelling to your property. Here's what changes and how Coolhouse plans are positioned to take advantage.
From 2026, the Government's National Environmental Standard for granny flats removes the need for building and resource consent for many minor dwellings up to 70m². The change is designed to lift housing supply, support multi-generational living and unlock under-utilised sections.
For Coolhouse owners and prospective clients, this is significant. Our Gran Cool, Crib and Mini plans sit within the parameters of the new rules and can be specified to deliver a fully self-contained, low-energy dwelling alongside an existing home.
While the consent pathway is simplified, the engineering, services and siting decisions remain critical. We continue to recommend an architect-led process to ensure your minor dwelling performs, complies and integrates with the wider site.
If you're considering adding a minor dwelling in 2026, get in touch — we can walk you through the design options, site requirements and likely timelines.
