Raise and Build Under Brisbane: How to Add Space Without Moving
If you own an older Queenslander in Brisbane, there’s a good chance you’re sitting on unused space right under your home.
Instead of moving, many homeowners are choosing to raise and build under to create new living areas, extra bedrooms, or even a full second level of usable space.
Done properly, this approach gives you more room without losing the character that makes Queenslander homes so appealing.
Here’s what you need to know before getting started.
What is a Raise and Build Under?
A raise and build under project involves lifting your existing home and constructing a new level underneath.
This allows you to:
- Add bedrooms or living areas
- Create open-plan kitchen and dining spaces
- Include garages, storage, or home offices

Is Your Queenslander Suitable?
Not every home is a perfect candidate.
You’re more likely to be suitable if:
- The home can be safely raised
- There is enough space for compliant ceiling heights
- The block allows for drainage and access
- The existing structure is in good condition
Homes in suburbs like Paddington, Ashgrove, Red Hill and Camp Hill are often strong candidates.
What Can You Build Underneath?
This is where the value is created.
Most homeowners use the new level to:
- Add extra bedrooms and bathrooms
- Create a second living area
- Build a modern kitchen and dining space
- Improve flow between indoor and outdoor areas
The goal is to make the lower level feel like a natural extension of the home.
How Much Does It Cost to Raise and Build Under?
Costs vary depending on the home, block, and level of finish.
As a guide:
- House raising: $30,000 – $100,000
- Excavation and structural work: $20,000 – $50,000
- Building underneath: $150,000+
- Approvals and engineering: $10,000+
Most full projects fall between $250,000 and $600,000.
The key is designing the project properly from the start to avoid costly changes later.
Height Requirements in Queensland
For a habitable space, the minimum ceiling height is generally 2.4 metres.
For non-habitable areas like storage or garages, this can be lower.
Your builder will help confirm what works based on your site and local council requirements.

- Increase property value
