North Shore Granny Flat Builders Built Around Your Property
North Shore features predominantly post war and Federation era homes on generous blocks, many exceeding 600 square metres. These spacious properties with leafy gardens and level to gently sloping blocks are ideal for granny flat additions. The established neighbourhood character and mature landscaping provide excellent settings for secondary dwellings.

From contemporary two bedroom designs in Chatswood to classic single bedroom studios in Mosman, we tailor each build to suit the property and streetscape. Our team has extensive experience navigating council requirements across all North Shore local government areas.
North Shore enjoys strong property values and consistent rental demand driven by proximity to the CBD, quality schools and harbour amenities. Granny flats in the area typically achieve weekly rents between $550 and $750 depending on size and location. Adding a quality granny flat provides excellent returns while maintaining the character of your established North Shore home.
