Mount Lewis Granny Flats Built Around Your Property
Mount Lewis features predominantly post war homes from the 1950s and 1960s, with many original fibro and brick dwellings on generous blocks typically ranging from 550 to 700 square metres. These larger block sizes provide excellent opportunities for granny flat construction, with most properties offering side or rear access and ample space for a compliant secondary dwelling without compromising the main home.
We build granny flats throughout Mount Lewis, Bankstown, Merrylands, Fairfield, Greenacre and Bass Hill, with extensive knowledge of Canterbury Bankstown Council requirements and approval processes. Our designs are specifically tailored to suit the established housing stock and block dimensions common throughout Western Sydney, ensuring your granny flat maximises available space while meeting all compliance standards. From compact studios to spacious two bedroom layouts, we deliver secondary dwellings that complement your property.
The Mount Lewis property market remains strong with consistent demand for affordable rental accommodation close to Bankstown CBD and major transport links. Granny flats in the area achieve rental returns of approximately $400 to $480 per week, providing excellent income potential for property owners. With housing affordability challenges driving demand for secondary dwellings, now is an ideal time to add a granny flat and increase your property value.
