Brisbane House Extensions
Being luxury home builders by trade, our team of extension builders specialise in a range of high-end home extension services.

Lift and Build Under
Our house extension builders specialise in lift and build under extensions to maximise the floorspace of your home. Popular for Queenslander style homes, we can raise the home and close in underneath, creating bedrooms, living spaces, or garage space. With our services you can easily double the amount of liveable space without sacrificing your yard space or needing to move. Our team of luxury builders are skilled in this process, ensuring a smooth and worry-free experience. Get better views, and an increased property value, with our lift and build under service.
Granny Flat Extensions
The perfect way to add more living space, functionality, and value to your property is to build a granny flat. Our granny flat extension services are treated like a new home build, being fully designed, planned, and built to match your current home. Granny flats are especially attractive if you have a large yard, as they can take up a significant amount of space. Whether you have older kids who want more privacy, family who visits often, or want to rent it out for extra money on the side, a granny flat is a solution that you should be considering.


Single Storey Extensions
A single storey extension is the top choice for those who want to expand their living space while keeping the home’s overall structure the same. Our services are perfect for adding a larger kitchen, dining, or living rooms. They can also be used to increase the size or number of bedrooms in your home to support a growing family. Single storey extensions are the perfect way to seamlessly blend indoor and outdoor living by creating open plan or alfresco spaces in your home. These extensions are usually the most cost-effective and straightforward ways to expand your home.
Second Storey Extensions
If you don’t have the luxury of being able to lift your home to build underneath, we can always add a second storey to the existing property. Our home extension builders can seamlessly blend the added second storey extension with your home’s current design. This service is great for adding extra bedrooms, bathrooms, or living spaces without sacrificing any yard space. Expertly designed by our luxury home builders, you won’t regret your choices. Significantly boost the size, liveability, and value of your home with our second storey extension services.
