Our approach to designing minor dwellings, small homes, and consent-exempt building work is to help you make the most of your site while navigating the rules with confidence.
Whether you're adding a secondary dwelling, exploring a small standalone home, or looking to understand what can be built without consent, we’re here to guide you through it.
Minor Dwellings & Granny Flats
Designing secondary dwellings and guiding you through local council requirements.
Other Consent Exempt Building Work
Advice and design support for work that may not require building consent.
Small Homes & Compact Living
Thoughtfully designed small dwellings that maximise space, comfort, and usability.
Airbnb & Short-Term Rentals
Designing flexible spaces suited to guest accommodation and short-term stays, with advice on local council requirements or limitations.
We focus on smart planning, natural light, and efficient use of space to create homes that feel bigger than their footprint. Even when building consent isn’t required, we help you navigate District Plan rules, site constraints, and service requirements to ensure your design is compliant and makes the most of your site.
