Grays Point Granny Flats Built Around Your Property
Grays Point features family homes built predominantly from the 1970s through to the 1990s, situated on generous blocks ranging from 700 to 1200 square metres. These spacious properties with large backyards are ideally suited to granny flat construction, providing ample room for a secondary dwelling while maintaining privacy. Most homes feature single storey brick and tile construction with established gardens backing onto bushland or waterway reserves.
We service Grays Point, Gymea Bay, Kirrawee, Yowie Bay, Oyster Bay and surrounding Sutherland Shire suburbs with granny flat designs tailored to local block sizes and bushfire prone land requirements. Our team has extensive experience with Sutherland Shire Council approval processes, ensuring compliant applications for studio, one bedroom and two bedroom granny flats. We design secondary dwellings that complement the established family home character of these peaceful waterside and bushland communities.
The Grays Point property market benefits from strong demand for independent accommodation near Royal National Park and Port Hacking waterways, with granny flats achieving approximately $450 to $550 per week in rental income. Rising property values and limited housing stock make secondary dwellings an attractive investment, providing multigenerational living options or passive income. Building a granny flat now capitalises on demand from downsizers and families seeking tranquil bushland lifestyle close to Cronulla beaches.
