    Cammeray Granny Flats Built Around Your Property

    Cammeray features predominantly federation and interwar homes built between 1900 and 1940, with many brick bungalows and weatherboard cottages on generous blocks averaging 600 to 800 square metres. These established properties offer excellent side or rear access, making them ideal candidates for granny flat construction. The spacious gardens and level blocks allow for secondary dwellings without compromising the character of the main residence.

    We service Cammeray, Mosman, Chatswood, Willoughby, Cremorne and Neutral Bay with a full range of granny flat designs including studios, one bedroom and two bedroom configurations. Our team has extensive experience navigating North Sydney Council requirements and designing secondary dwellings that complement the established character of North Shore homes. Each granny flat is tailored to suit the specific dimensions and access points of your block.

    Cammeray’s property market continues to strengthen with median house prices exceeding $2.8 million, making granny flats an attractive way to maximise property value and generate rental income. Strong demand from young professionals working in North Sydney and the CBD drives rental returns, with one bedroom granny flats achieving $550 to $650 per week. Building a granny flat now allows homeowners to capitalise on this demand while creating flexible accommodation for family or tenants.
