IS YOUR PROPERTY READY FOR A GRANNY FLAT?

We’re proud to serve homeowners throughout Hurstville, Penshurst and Mortdale with our licensed team managing everything from DA approval through to handover.
Hurstville Granny Flats Built Around Your Property
Hurstville features predominantly brick homes built from the 1950s through to the 1980s, with many properties sitting on generous blocks of 550 to 700 square metres. These established blocks typically offer excellent side or rear access, making them ideal candidates for standalone granny flats. The combination of good block depth and wide frontages means most properties can accommodate a quality secondary dwelling without compromising existing gardens or outdoor space.
We build granny flats throughout Hurstville, Penshurst, Mortdale, Beverly Hills, Allawah and Blakehurst, bringing deep knowledge of Georges River Council requirements to every project. Our designs include studio configurations, one bedroom layouts and full two bedroom granny flats tailored specifically to the block dimensions common throughout the St George area. We understand local setback rules, drainage considerations and how to maximise your buildable area while maintaining neighbourhood character.
The Hurstville property market remains strong thanks to its direct train line to the CBD, Westfield shopping hub and excellent schools driving consistent rental demand. Quality granny flats in the area achieve $450 to $600 per week, providing excellent returns for homeowners while meeting strong demand for independent rental accommodation. With established blocks becoming increasingly valuable, adding a secondary dwelling now maximises your property’s income potential and future resale appeal.
