Glenfield Granny Flats Built Around Your Property
Glenfield features predominantly brick homes from the 1960s through to the 1990s, with generous block sizes typically ranging from 550 to 700 square metres. These established properties offer excellent side and rear access, making them ideal candidates for granny flat construction. The spacious backyards common throughout the suburb provide ample room for a quality secondary dwelling without compromising the main residence.
We service Glenfield and surrounding South West Sydney suburbs including Liverpool, Campbelltown, Casula, Ingleburn, Macquarie Fields and Edmondson Park with a full range of granny flat designs. Our team has extensive knowledge of Liverpool City Council requirements and complying development pathways, ensuring smooth approvals for your project. We tailor every design to suit the larger suburban blocks typical of this area, maximising your investment.
Glenfield’s property market benefits from strong rental demand driven by proximity to rail transport, Liverpool Hospital and Western Sydney University. Granny flats in this area achieve rental returns of approximately $380 to $450 per week for quality two bedroom designs. With property prices remaining accessible compared to inner Sydney and growing infrastructure investment in South West Sydney, now is an ideal time to add a secondary dwelling.
