Granny Flat Designs and Sizes in Townsville

Most Townsville secondary dwellings are planned up to the local size cap (90 m² GFA). Layout choice depends on who will live there and how much of the yard you want to keep.

• Studio: best for a single occupant, office or guests; lowest cost band
• One bedroom: best balance of privacy, cost and footprint
• Two bedroom: strongest rental layout where size rules allow

Detached flats give the most privacy. Attached flats can share a wall and save yard. Garage conversions must meet the National Construction Code as a habitable dwelling — often more work than people expect.

Design tips: face entry and outdoor space away from the main house living areas; keep a side path for separate access; plan storage and laundry early; design for cross-ventilation and strong rangehood extraction in a tropical climate.
