These established brick and fibro homes with wide rear yards and good side access are ideally suited to granny flat additions, offering ample space for a quality secondary dwelling without compromising the main home’s outdoor living areas.

Our teams specialise in one and two-bedroom self-contained granny flats that suit the area’s established blocks, with designs that complement existing homes while maximising rental appeal in this high-demand lifestyle region. We understand local council requirements across Sutherland Shire Council and deliver projects meeting all DA and CDC conditions.
