About this category
2 1 bedroom granny flats designs.
A 1-bedroom granny flat is the most common secondary dwelling format for owners who need a fully self-contained space but want to preserve backyard area. Perfect for a parent, an adult child, a long-term guest or a home office that doubles as an occasional guest suite.
Every 1-bedroom plan below stays under the 60m² CDC pathway cap, meaning fast-track approval in as little as 10 business days on eligible blocks (minimum 450m² primary block). The separated bedroom gives genuine privacy from the open-plan living zone — a step up from a studio conversion.
