Harris Park Granny Flats Built Around Your Property
Harris Park features predominantly established homes built from the 1950s through to the 1990s, with typical block sizes ranging from 550 to 700 square metres. These generous blocks with side access are ideal for granny flat construction, offering ample space for a self-contained dwelling. Most properties feature brick or weatherboard homes with established gardens and enough room for a quality secondary dwelling.
We service Harris Park and surrounding suburbs including Parramatta, Westmead, Rosehill, Granville, North Parramatta and Merrylands with granny flat solutions tailored to local blocks. Our team has extensive knowledge of Cumberland Council requirements and processes, ensuring smooth approvals for studio, one bedroom and two bedroom granny flats. Every design is customised to suit your block size, access and existing home layout.
Harris Park’s property market remains strong due to its proximity to Parramatta CBD, Westmead Medical Precinct and excellent public transport. Rental demand is consistently high, with granny flats typically achieving $450 to $550 per week.
