Garage Conversions in Mount Gravatt
Converting single and double garages into habitable rooms - bedrooms, home offices, studios, gyms, media rooms and self-contained retreats - including approvals, insulation, lining, flooring, lighting and replacement parking. Orange Projects is a QBCC-licensed builder (Licence No. 15620733) delivering garage conversions across Mount Gravatt and the wider Brisbane region.
Garage Conversions in Mount Gravatt - what to expect
Mount Gravatt is a central southside suburb with excellent transport links and a wide range of housing ages, from post-war cottages to modern townhouses. Post-war and 1960s homes, brick houses from the 70s and 80s, and newer townhouse complexes. Kitchens, bathrooms, flooring and internal reconfigurations dominate. For garage conversions specifically, this matters. Slope is a constant here, and many homes have partially enclosed lower levels that were never done to standard. We correct waterproofing, head height and framing issues as part of any legal conversion. Every Mount Gravatt project is quoted at a fixed price after a site inspection, delivered by one licensed team, and finished with the documentation and warranties you should expect from a licensed builder.

Approvals and compliance
A garage is not habitable space until it is approved as habitable space. That means ceiling height, natural light and ventilation, insulation, floor level above the surrounding ground, moisture protection and egress all have to be brought up to standard, and on-site parking usually has to be replaced. We prepare the drawings, engage the engineer and run the private certifier so the room is legal and shows up correctly when you sell.
Making it feel like part of the house
The giveaway on a bad conversion is the door opening, the floor step and the ceiling height. We infill the garage opening with properly framed windows and cladding that matches the facade, raise or level the slab where needed, line and insulate walls and ceiling, and carry the same skirting, architrave and paint through from the rest of the home so the room reads as original.
Comfort, services and storage
Insulation to walls and ceiling, new power and data circuits, lighting, ceiling fans or split-system air conditioning, and where the brief calls for it, plumbing for a bathroom or kitchenette. We also plan replacement storage - built-in joinery or an external shed - because that is the thing owners miss most after the garage is gone.

Frequently asked questions - Mount Gravatt
Do I need approval to convert a garage in {loc}?
Yes, in almost every case. Converting a garage into habitable space is a change of building classification, so it needs building approval covering ceiling heights, natural light and ventilation, floor levels, insulation, egress and often replacement on-site car parking. We handle the drafting, engineering and private certifier for Mount Gravatt projects as part of the quote.
How much does a garage conversion cost in {loc}?
A single garage conversion in Mount Gravatt typically runs $25,000-$45,000 for a finished room with insulation, lining, flooring, lighting and power. Adding a bathroom or kitchenette, raising the slab, or converting a double garage into a self-contained studio pushes the range to $50,000-$90,000.
Will I lose value by removing the garage?
Only if the parking is not replaced. In Mount Gravatt we usually pair the conversion with a carport, hardstand or reconfigured driveway so the home keeps compliant parking while gaining a bedroom, studio, office or teenage retreat - which is normally where the value gain sits.
