South Granville Granny Flats Built Around Your Property
South Granville features predominantly brick homes from the 1960s and 1970s, with many properties sitting on generous blocks of 550 to 700 square metres. These spacious backyards provide excellent opportunities for granny flat construction without compromising existing garden space. The typical single storey layout and wide side access make these established properties ideal for adding secondary dwellings.
We service South Granville and surrounding suburbs including Bankstown, Merrylands, Fairfield, Guildford, Yennora and Chester Hill with expert granny flat construction. Our team has extensive knowledge of Cumberland Council requirements and can design studio, one bedroom and two bedroom granny flats tailored to your block. We specialise in maximising the potential of established Western Sydney properties with designs that suit local conditions.
South Granville’s property market benefits from strong rental demand driven by proximity to Parramatta, transport links and Western Sydney employment hubs.
