Minor Dwellings & Granny Flats

Looking to add a granny flat to your property? This is one of the best ways to add long-term value to your home, create flexible living arrangements for family, or generate rental income.

From January 2026, the new NZ building rules mean granny flats up to 70m² can be built without full building consent, making the process faster and more affordable than ever before. As experienced residential builders, we can guide you through what's required under the new framework and get your project moving quickly.

The new laws require adherence to a specific set of requirements in order to meet the granny flat exemption. Some dwellings, while they may be under 70m², might not fall under the exemption. This will depend on your specific property and plans. Read more about what makes a property a granny flat on our blog post here.

Whether you need a self-contained unit, a sleepout, or a fully independent dwelling, we handle the build from the ground up, including foundations, framing, exterior cladding, and fit-out.

Not sure if your property is suitable or what consents you'll need? Get in touch - we’re happy to talk it through.

    • Full project management from design to completion

    • Coordination with designer, engineers and council (as needed)

    • Advice on consent requirements under 2026 NZ rules
