Smithfield Granny Flats Built Around Your Property
Smithfield features predominantly established homes built from the 1960s through to the 1990s, sitting on generous blocks typically ranging from 550 to 700 square metres. These larger Western Sydney blocks provide excellent space for granny flat construction without compromising the main residence or backyard amenity. Most properties follow a classic quarter acre subdivision pattern with side access and ample rear yard space.
We service Smithfield and surrounding Canterbury Bankstown suburbs including Bankstown, Merrylands, Fairfield, Wetherill Park, Prairiewood and Greystanes with expert granny flat construction. Our team has extensive knowledge of Canterbury Bankstown Council requirements and designs studio, one bedroom and two bedroom granny flats tailored to the generous block sizes common throughout this Western Sydney region. Every project is customised to suit your property layout and local planning controls.
The Smithfield property market benefits from strong rental demand driven by Western Sydney’s growing population, transport connections and employment hubs. Granny flats in this area typically achieve weekly rental returns of $400 to $500, providing excellent investment potential for homeowners. With housing affordability pressures increasing across Sydney, now is an ideal time to add a secondary dwelling and generate passive income.
