    Glenorie Granny Flats Built Around Your Property

    Glenorie features predominantly acreage and large block properties built from the 1970s onwards, with many rural residential homes on expansive land parcels. These generous block sizes are ideal for granny flat construction, offering ample space for secondary dwellings without compromising the main residence. Most properties feature single storey homes with established gardens and plenty of room for additional development.

    We service Glenorie and surrounding suburbs including Castle Hill, Dural, Kellyville, Galston, Annangrove and Arcadia with expert granny flat construction tailored to Hills District properties. Our team has extensive knowledge of The Hills Shire Council requirements and Hornsby Shire Council regulations for complying development. We design studio, one bedroom and two bedroom granny flats specifically suited to the larger blocks typical of this rural residential area.

    The Glenorie property market has seen strong growth as buyers seek lifestyle properties within commuting distance of Parramatta and the Northwest. Rental demand remains solid for quality secondary dwellings, with granny flats achieving $400 to $500 per week. Building a granny flat now allows homeowners to capitalise on rental income while adding substantial value to their acreage property.
