    Constitution Hill Granny Flats Built Around Your Property

    Constitution Hill features established homes predominantly built from the 1970s through to the 1990s, with generous block sizes typically ranging from 600 to 800 square metres. These spacious parcels provide excellent opportunities for granny flat development, with most properties offering side or rear access and ample setback space. The area’s traditional quarter acre blocks are ideally suited to modern secondary dwellings without compromising the existing home or garden amenity.

    We service Constitution Hill and surrounding suburbs including Guildford, Merrylands, Wentworthville, Greystanes, Pemulwuy and Old Toongabbie with expert granny flat construction. Our deep knowledge of Cumberland Council requirements ensures smooth approvals for studio, one bedroom and two bedroom designs. Each granny flat is tailored to suit the generous blocks typical of this established Hills district location, maximising space and functionality.

    Constitution Hill’s property market benefits from strong rental demand driven by proximity to Parramatta CBD, Westmead Hospital and major transport routes. Granny flats in the area achieve rental returns of approximately $400 to $480 per week, providing excellent investment potential. With ongoing infrastructure development across the Hills and Parramatta region, now is an ideal time to add a secondary dwelling and capitalise on consistent tenant demand.
