Penshurst Granny Flats Built Around Your Property
Penshurst features predominantly post-war and mid-century family homes built from the 1950s through to the 1980s, typically sitting on generous 550 to 700 square metre blocks. These established properties offer excellent rear and side access, making them ideal candidates for granny flat additions. The spacious block sizes common throughout the suburb provide ample room for a comfortable secondary dwelling without compromising the main residence.
We build granny flats throughout Penshurst, Hurstville, Mortdale, Beverly Hills, Oatley and Peakhurst, bringing deep knowledge of Georges River Council requirements to every project. Our designs are specifically tailored to suit the established block layouts and streetscapes common across the St George area. Whether you need a compact studio or a full two-bedroom granny flat, we deliver solutions that complement your existing property.
Penshurst’s property market remains strong due to its excellent train connectivity to the CBD and highly regarded school catchments driving consistent rental demand. Granny flats in the area typically achieve $450 to $550 per week in rental income, providing excellent returns for investors and homeowners. With increasing demand for quality rental accommodation near transport hubs, now is an ideal time to add a granny flat to your Penshurst property.
