    Cremorne Granny Flats Built Around Your Property

    Cremorne features predominantly established homes from the 1920s to 1960s, with Federation, Californian bungalow and post war brick homes throughout the suburb. Block sizes typically range from 550sqm to 900sqm, with many properties offering side access and deep rear gardens. These generous North Shore blocks provide excellent opportunities for self contained granny flats without compromising the established character or garden space.

    We service Cremorne, Mosman, Neutral Bay, Chatswood, Willoughby and surrounding North Shore suburbs with extensive knowledge of North Sydney Council requirements. Our granny flat designs include studios, one bedroom and two bedroom configurations tailored specifically to established North Shore blocks. We understand local planning controls and work closely with council to ensure compliant, quality secondary dwellings that enhance your property value.

    The Cremorne property market remains strong with established homes regularly exceeding $3 million, making granny flats an intelligent investment for rental income or family accommodation. Rental demand is consistently high due to proximity to the CBD, harbour access and excellent North Shore schools, with granny flats achieving $650 to $850 per week. Building a granny flat now maximises your property’s income potential in this tightly held, desirable location.
