Add A Secondary Dwelling To Your Home

In September 2022, restrictions on who can live in secondary dwellings in Queensland were changed to enable homeowners to rent out secondary dwellings such as granny flats. That means if you have the space on your property, you could create a second income stream by building and renting out a granny flat.


At Coast Construct Co, we’re experts in building granny flats on the Gold Coast and will obtain all the necessary approvals and certifications for your project.


Our team of granny flat builders will visit your home and discuss your requirements before working with an architect and engineer to create detailed plans. We’ll then get started and ensure you are kept in the loop throughout the entire process.

Additional Living Space

A granny flat adds comfortable, self-contained living space ideal for teenagers, extended family, or independent living—designed to feel private while staying connected to your main home.

Home Office

Create a quiet, dedicated workspace away from the main house. Perfect for business owners, remote workers, or creatives needing a professional, distraction-free environment.

Guest House

Offer visitors their own retreat with a fully equipped guest house. It provides privacy, comfort, and convenience for friends or family staying overnight or for longer visits.

Storage Space

A granny flat can double as organised storage, keeping tools, equipment, or seasonal items protected and out of your main home while still being easily accessible.

How You Might Use a Granny Flat

Modern bathroom with white walls, patterned floor tiles, and a wooden vanity.
