Northwood Granny Flats Built Around Your Property
Northwood features established homes built predominantly from the 1950s through to the 1980s, with substantial blocks typically ranging from 600 to 900 square metres. These generous allotments with deep backyards are ideal for granny flat additions, offering ample space for secondary dwellings without compromising the main residence. The leafy streetscapes and mature gardens provide perfect settings for self-contained units that complement the neighbourhood character.
We service Northwood and surrounding North Shore suburbs including Mosman, Chatswood, Willoughby, Lane Cove, Northbridge and Greenwich with expertly designed granny flats tailored to local council requirements. Our team has extensive knowledge of North Sydney Council and Lane Cove Council regulations, ensuring compliant designs that maximise your property’s potential. From studios to full two-bedroom dwellings, we deliver granny flats suited to North Shore blocks and streetscapes.
The Northwood property market remains strong with median house prices consistently above $2 million, making granny flats a smart investment for homeowners seeking additional income or multi-generational living solutions. Rental demand is solid across the North Shore, with quality one-bedroom granny flats achieving $550 to $650 per week. Now is an ideal time to build, adding substantial value to your property while meeting growing demand for quality rental accommodation.
