Northbridge Granny Flats Built Around Your Property
Northbridge features established homes predominantly built from the 1950s through to the 1980s, with generous block sizes typically ranging from 600 to 1000 square metres. These spacious blocks with side access and level yards are ideal for granny flat construction. Most properties feature traditional brick homes with landscaped gardens that can easily accommodate a quality secondary dwelling.
We service Northbridge and surrounding North Shore suburbs including Mosman, Chatswood, Willoughby, Cammeray, Naremburn and Castlecrag with our full range of granny flat designs. Our team has extensive knowledge of Northern Sydney council requirements and can navigate local planning regulations efficiently. We tailor every design to suit the generous North Shore blocks and complement the established character of your neighbourhood.
Northbridge’s strong property market and proximity to the CBD, Chatswood and harbour foreshore drive consistent rental demand across the lower North Shore. Quality granny flats in the area command around $650 to $750 per week, providing excellent investment returns for property owners. With housing affordability pressures and multigenerational living trends, now is an ideal time to add a secondary dwelling.
