Granny flat plans in Brisbane
A granny flat, known in the planning system as a secondary dwelling, is a self contained second home on the same lot as your main house. It's one of the most effective ways to add rental income or house family in Brisbane. Plan Draft provides fixed price granny flat drawings for homeowners on standard residential lots.
We produce the full documentation set your building certifier needs, site plan, floor plan, elevations, roof plan, cross section and specification notes. Both attached and detached secondary dwellings are within the standard fixed price scope.
In Brisbane a secondary dwelling is generally limited to 80m² of habitable floor area as accepted development under Brisbane City Plan 2014. It must sit within 20 metres of the main dwelling, and overall site coverage can't exceed 50%. Larger proposals (up to around 90m²) require a development application.
Since September 2022, a secondary dwelling in Queensland can be rented to anyone, it no longer has to be lived in by a member of the household. Character, heritage, flood and waterway overlays are common across Brisbane; we check suitability against the relevant planning scheme before any work begins, at no cost to you.

Common questions
Yes. A secondary dwelling needs a building approval, and can often be approved as accepted development under Brisbane City Plan 2014 if it meets the size, setback and site coverage rules.
