IS YOUR PROPERTY READY FOR A GRANNY FLAT?
Monstructions specialises in building granny flats in Lugarno on the generous riverside blocks that define this prestigious St George suburb. We’re proud to serve homeowners throughout Lugarno, Peakhurst and Hurstville with our licensed team managing everything from DA approval through to handover.
Lugarno Granny Flats Built Around Your Property
Lugarno features predominantly original homes from the 1960s and 1970s built on generous blocks, with many properties offering 600 to 800 square metre lots. These spacious riverside blocks provide ample space for a secondary dwelling without compromising the main residence or garden areas. The established layout of most Lugarno properties makes them ideal candidates for granny flat additions.
We service Lugarno, Peakhurst, Riverwood, Hurstville, Oatley and Mortdale with custom granny flat designs tailored to the generous blocks typical of the St George area. Our team has extensive experience with Georges River Council requirements and planning controls specific to riverside suburbs. Whether you need a studio, one bedroom or two bedroom granny flat, we design solutions that maximise your property’s potential.
Lugarno’s median property values exceed $2 million, making granny flats a smart investment for homeowners seeking rental income or multigenerational living options. Strong rental demand from young professionals and downsizers means quality granny flats command $550 to $700 per week in this sought after riverside location. Adding a secondary dwelling now capitalises on Lugarno’s premium property market and growing housing demand.
