Yes, granny flats are legal in Australia, but the specific rules and regulations governing their construction and use can vary significantly between states and territories, and even between different local council areas. 

Our extensive in-house market research shows that a three bedroom granny flat is the optimal configuration in Queensland. It terms of rental, it offers maximum return. Local real estate agents believe that a well-designed three bedroom granny flat can add up to 30% to the value of an existing property.

Our managing director Dr Bruce Dwyer’s research showed that the Queensland granny flat market was set to boom after the State Government relaxed the laws on renting backyard granny flats. It became clear that an attractive granny flat could pay for itself. 

Presently Granny flat manufacturers range from cheap crude container conversions (Councils hate them and they will not be able to comply with the new NCC 2023) to site built homes. Some of the latter are the equivalent of a small economy class house and can take a very long time to build.

Our passion is building feature-rich homes designed to stand the test of time. We are fully committed to reducing electricity consumption, ensuring the use of safe and high-quality building materials, and guaranteeing timely delivery of our homes.

A granny flat, commonly found in Australia, is a small, self-contained living unit typically located on the grounds of a single-family home. It’s designed to accommodate one or two people and includes essential amenities like a kitchen, bathroom, and living space. The term “granny flat” originated from its popular use as a convenient and close-by residence for elderly family members, such as grandparents, allowing them to live near their families while maintaining a degree of independence.

In addition to housing elderly relatives, granny flats in Australia are often used for various other purposes. They can serve as a private space for adult children still living at home, a source of rental income, a guest house for visitors, or even as a home office or studio. These flats are a practical solution for expanding living space on your existing property without the need to buy a bigger home.

Granny flats are particularly valuable because they can enhance the value of your property and offer an efficient way to meet housing needs without expanding your property’s footprint. At Moncasa, we’re committed to understanding the unique requirements of building a granny flat, ensuring it fulfills its intended purpose while also blending seamlessly with your property and the surrounding area.



Granny flats can be either attached or detached. However, detached granny flats are usually more cost-effective

As of late 2022, Queensland laws changed to allow granny flats to be rented to non-family members. This change was made in response to the housing crisis
