Western Sydney is one of the best parts of the city for a granny flat. The blocks are generous, plenty of homes have usable backyards, and most sites qualify for the fast complying development pathway. As local builders, we make the process simple from first enquiry to handover.

Why Western Sydney suits a granny flat

Two things make the western suburbs ideal. First, the land. Established suburbs around Penrith, Blacktown, Liverpool and Campbelltown have many detached homes on blocks of 450 square metres or more, which is the usual threshold for complying development. Second, demand. Western Sydney has strong rental demand and a lot of multigenerational families, so a second dwelling gets used whether you build it for family or for income. Our factories at Bringelly and Elong Elong sit close to most of these suburbs, so transport and installation are quick and tidy.
