Designs to suit your lifestyle
Every block and every household is different, so we offer a range of 1 bedroom granny flat designs and floor plans to suit your style and your needs. Smart, open-plan living and an open-plan kitchen make a single-bedroom layout feel bright and spacious, while built-in wardrobes and clever storage keep everything in its place.
We can build in thoughtful accessibility features, like wider doorways and no-step shower bases, for comfortable living at every stage of life. Your granny flat can be a detached build or an attached addition, designed to suit your block and finished with the materials, layout and optional extras that make it your own. Every 1 bedroom granny flat is custom designed and energy efficient, tailored around the way you live.
Rules and approvals
Like any secondary dwelling, a 1 bedroom granny flat must comply with your local council regulations. The rules are often more straightforward than people expect, but a few standard requirements apply:
- A maximum floor area generally up to around 60m², and up to 80m² in some areas
- Positioning within 10m of the main house, with only one granny flat permitted per lot
- At least one additional dedicated off-street parking space
- Shared essential services, water, sewerage and power, with the main house
To ensure compliance, building approval is required before construction. Our team checks exactly what applies to your site, prepares the paperwork and liaises with your local council, so you don’t have to.
