Granny flat plans
A granny flat has to be a complete home in a footprint most councils cap, so every square metre is contested. The layouts here treat the kitchen, bathroom and laundry as one wet zone against a single wall, which keeps the plumbing short and leaves the remaining area for living and sleeping.
20 editable layouts. Open one in the editor to move walls and rooms, then read the material quantities measured off your own drawing. PlanHome measures; your builder prices it with their rates.

Common questions
- How big can a granny flat be?
- The cap is set by your state and council, and 60 m² is a common figure in several jurisdictions, but it varies and some allow more. Confirm the limit that applies to your block before you finalise a layout, because designing to the wrong number wastes the whole exercise.
- Do I need council approval for a granny flat?
- Almost always, though some states offer a faster complying-development pathway when the design meets set criteria. That approval needs documentation from a draftsperson or building designer. A plan drawn here gets you to that conversation with real dimensions rather than a sketch.
