Prices vary depending on size and finish, but modular granny flats in Perth typically start from around $19,000 for a compact studio-style build, with fully-equipped one and two-bedroom options ranging higher depending on layout and inclusions. Traditional site-built granny flats in WA can run considerably more once council approval, site works, and services connections are factored in — a modular build is generally the more cost-effective route to a self-contained space.

The most functional small granny flat layouts keep living, kitchen, and dining in one open-plan space to maximise the sense of room, with the bedroom and bathroom tucked to one side for privacy. Good natural light, built-in storage, and a covered entry all make a compact footprint feel larger without adding square metres. Our team can walk you through layout options that suit your specific block and use case.

The right builder depends on your budget, timeline, and how self-contained you need the space to be.

Under WA's Residential Design Codes (R-Codes), a granny flat (ancillary dwelling) can have a maximum internal floor area of 70m². Units at or under this size on residential land generally don't require planning approval — though a building permit is still needed, and setback requirements still apply. Our range is designed to make the most of that 70m² allowance while staying fully compliant.
