Granny Flat Builders Gold Coast

Whether you're housing extended family, creating a rental income stream or adding flexible space for the future, a granny flat is one of the best-value additions you can make to a Gold Coast property.
Refresh Renovations designs and builds granny flats and secondary dwellings across the Gold Coast, handling everything from design and council approvals through to construction and handover.
Why build a granny flat?
- Multi-generational living. Keep ageing parents or adult kids close while giving everyone their own space and privacy.
- Rental income. Queensland rules allow secondary dwellings to be rented out, making a granny flat a genuine investment that can pay itself off over time.
- Flexible space. Home office, guest accommodation, Airbnb, teenage retreat: a self-contained dwelling can change roles as your life does.
- Added property value. A well-built secondary dwelling broadens the appeal of your property to buyers and investors alike.
What we build
Every site and every household is different, so we design to suit. That might be a compact one-bedroom flat tucked behind the main house, a two-bedroom dwelling with its own outdoor area, a garage conversion, or a self-contained space attached to your existing home. Your Renovation Consultant will help you work out the best option for your block, your budget and your council's requirements.
All our granny flats are fully self-contained, with kitchen, bathroom, laundry provisions and their own entrance.
Approvals handled for you
Secondary dwellings on the Gold Coast need to comply with council planning rules covering things like dwelling size, setbacks and site coverage. Your Renovation Consultant manages the approvals process as part of the project, working with certifiers and council so you don't have to navigate the paperwork yourself.
How much does a granny flat cost on the Gold Coast?
Costs depend on size, site access, services connections and the level of finish. As a rough guide, a granny flat build typically ranges from around $150,000* to $300,000*+, with garage conversions and attached dwellings often coming in lower than standalone builds. You'll receive a fixed quote before construction starts, based on your specific site.
