Keep your family close, with Cubitt’s personalised and affordable Granny Flats.
Is your family growing? Many Australians are finding Granny Flats to be the perfect solution to accommodate more of the family within the existing property they love, where their most precious memories have been made.
It can be a time-consuming and expensive process to buy and sell your home, do all the cleaning and paperwork required, negotiate terms not to mention packing and physically moving location! A financially savvy alternative to boost your property’s worth and achieve extra space, is by investing in one of Cubitt’s spacious 1 Bedroom, 2 Bedroom and even 3 Bedroom Granny Flat models.
Cubitt's Granny Flats is family owned and operated, and a business you can rely on. In 25 years, our team have successfully built over 1,700 Granny Flats across NSW and the ACT.

At Cubitt’s, our experienced council planning teams liaise with Council for all approvals, and we even provide the latest WiFi and Smart Home technology, so there’s no need for you to deal with messy NBN connections.
We take the time to understand your needs, and offer customised solutions to fit your budget and specific requirements, such as wheelchair ramps and wider doorframes. Perhaps you enjoy a lifestyle of entertaining? Add extended decking, an outdoor alfresco area or even expanded pantry space with our custom Granny Flat solutions, so you can design the perfect home for you.
