Once built to house elderly relatives or extended family, the modern granny flat can be used for a huge range of purposes.
A granny flat is a detached or semi-detached residence built adjacent to the main home. Usually, granny flats are designed for one or two people, either with a single bedroom or, at the most, two bedrooms.
Most granny flats feature all the facilities of a standard house, just smaller. Compact homes like these often require clever design and planning consideration to ensure the space is functional as well as enjoyable to live in. Granny flats can be fully self-contained; however, some may share facilities such as the laundry or outdoor entertaining areas with the main house.
Granny flats are sometimes referred to as guest houses, cottages, and as mentioned above, tiny houses. Regardless of what you call it or what you’re planning to use it for, building a granny flat onto your home has many great advantages.
Adding a second dwelling to your property offers a unique blend of lifestyle flexibility, privacy and space as well as financial security. There are many reasons to invest in building a granny flat on your property, but the most popular ones include:
Converting your garage into a granny flat is an affordable alternative to building a new structure from scratch. By utilising the existing roof and slab, you can seriously reduce the building and construction costs. However, make sure that the space is waterproofed, insulated and meets the Building Code of Australia (BCA) standards to ensure it’s legal before anyone moves in.

Unfortunately, you can only build one granny flat per property. Your granny flat must be smaller than the main house and within 20 metres of it. Before building a granny flat on your property, it’s important to have a look at your council’s website to find out your local zoning and infrastructure laws and regulations.
Most Gold Coast granny flats are designed with one or two bedrooms. Adding more will limit your total floor space, making it feel cramped and uninviting.
