Annangrove Granny Flats Built Around Your Property
Annangrove features spacious acreage properties and large residential blocks, with many homes built from the 1980s onwards across this semi-rural Hills district locality. The generous block sizes, often exceeding 2,000 square metres, provide excellent opportunities for secondary dwellings without compromising garden space. These established properties typically feature single-storey brick homes with expansive rear yards ideal for granny flat construction.
We service Annangrove and surrounding suburbs including Glenhaven, Kenthurst, Castle Hill, Kellyville, Rouse Hill and Dural with expert granny flat construction. Our team has extensive knowledge of The Hills Shire Council requirements and designs granny flats specifically suited to the area’s larger rural residential blocks. Whether you need a studio, one bedroom or full two-bedroom secondary dwelling, we tailor every design to your property.
The Annangrove property market benefits from strong demand for rental accommodation as families seek the Hills district lifestyle close to quality schools and amenities. Granny flats in this area can achieve weekly rents from $450 to $600, providing excellent returns for property owners. With ongoing development in surrounding suburbs and limited rental stock, now is an ideal time to add a secondary dwelling.
