The typical properties sit on 550 to 700 square metre blocks with deep backyards, providing ample space for a complying granny flat. These established homes with mature gardens are ideal for adding a secondary dwelling without compromising the main residence.

Our team has extensive knowledge of Georges River Council requirements and processes, ensuring smooth approval for studio, one bedroom and two bedroom granny flats.
