Longueville Granny Flats Built Around Your Property
Longueville features established homes predominantly built between the 1920s and 1960s, with elegant Federation, Californian bungalow and post war properties set on generous blocks. Many properties offer large backyards with water views, making them ideal candidates for secondary dwellings that maximise both outlook and investment potential. The mature gardens and spacious allotments provide excellent opportunities for thoughtfully designed granny flats.
We service Longueville and surrounding North Shore suburbs including Greenwich, Lane Cove, Northwood, Riverview, Hunters Hill and Woolwich. Our team has extensive experience working with Lane Cove Council, ensuring your granny flat meets all local planning requirements and complements the area’s established character. We design studios, one bedroom and two bedroom flats specifically tailored to North Shore blocks and streetscapes.
The Longueville property market remains strong with median house prices consistently above $3 million, driving demand for additional income streams through granny flats. Rental demand is high across the Lower North Shore, with quality one bedroom granny flats achieving around $650 per week. Building now allows homeowners to capitalise on strong rental returns while adding significant value to their property.
