Busby Granny Flats Built Around Your Property
Busby features established homes from the 1970s and 1980s, predominantly on generous blocks ranging from 550 to 700 square metres. These spacious lots provide excellent opportunities for granny flat construction, with typical properties offering deep backyards and side access. The established nature of the suburb means homeowners can add secondary dwellings without compromising existing gardens or outdoor living areas.
We service Busby and surrounding suburbs including Liverpool, Campbelltown, Casula, Green Valley, Miller and Cartwright with a full range of granny flat designs. Our team has extensive knowledge of Liverpool City Council requirements and specialises in studio, one bedroom and two bedroom configurations. Every design is tailored to suit the larger blocks typical of this South West Sydney area.
The Busby property market benefits from strong rental demand driven by proximity to Liverpool CBD, transport links and employment hubs. Granny flats in the area achieve weekly rents of $380 to $450, delivering excellent returns for investors and homeowners. With housing affordability pressures across South West Sydney, now is an ideal time to build and capitalise on consistent tenant demand.
