Granny Flats and Minor Dwellings
A well designed granny flat or minor dwelling can add flexibility, value, and extra living space to your property. Cain Built helps homeowners with building a granny flat that feels comfortable, modern, and perfectly suited to the needs of extended family, guests, or tenants.

Smart, Practical Design
We support clients through all stages of building a granny flat, from early planning and council requirements to the full construction process. A well built unit can provide a private and functional space that sits naturally alongside your main home.
If you are considering building a minor dwelling in Auckland, our team will help you assess the site, design a layout that works for your section, and deliver a building that meets New Zealand regulations.
Auckland Granny Flat Construction
Many homeowners choose to build granny flats to create space for grandparents, independent living for adult children, or a separate work from home area. Whether attached or standalone, we ensure the design complements the existing home and works with your site.
Cain Built also works with clients who are planning on building a minor dwelling, delivering layouts that make the most of small footprints while still feeling comfortable and welcoming.
Renovating Existing Granny Flats
Older units often benefit from modern updates. Our team completes granny flat renovations that improve warmth, layout, and usability. From modernising interiors to updating joinery, insulation, and bathroom facilities, we help bring dated spaces up to current standards.
Council Requirements and Compliance
Building secondary dwellings often requires careful planning around local rules, setbacks, and service connections. We assist with documentation, engineering, and the approval process to make building a minor dwelling as straightforward as possible.
Built With Care and Experience
Cain Built provides full project management for all types of small home construction. Whether you are building a granny flat, upgrading an existing unit, or planning on building a minor dwelling, our team of professional granny flat builders delivers clear communication and high quality craftsmanship throughout the entire build.
