Kirribilli Granny Flats Built Around Your Property
Kirribilli features predominantly Federation and early 20th century homes on compact blocks, with many properties offering 400 to 600 square metre sites. These established North Shore homes typically sit on sloping or terraced blocks with traditional layouts and mature gardens. The compact block sizes are ideal for well designed granny flats that maximise available space while respecting the character of this heritage rich harbourside suburb.
We service Kirribilli and surrounding North Shore suburbs including Mosman, Chatswood, Willoughby, Neutral Bay, Cremorne and Milsons Point with a full range of granny flat designs. Our team has extensive knowledge of North Sydney Council requirements and planning considerations specific to this prestigious area. We tailor each design to suit compact North Shore blocks, sloping sites and the character of established Federation and early century homes.
Kirribilli’s harbourside location, proximity to the CBD and exceptional amenity drive strong property values and rental demand in this tightly held North Shore enclave. A quality one bedroom granny flat in Kirribilli can achieve $650 to $750 per week in rental income. With limited housing stock and high demand from professionals and downsizers, now is an ideal time to add a secondary dwelling to your Kirribilli property.
