Lift & Build Under Brisbane

If your Brisbane home is sitting on a good block but running short on space, lifting and building under is one of the smartest investments you can make. Rather than moving to a bigger property, which comes with stamp duty, real estate fees, and the hassle of relocating, a lift and build under gives you the extra room your family needs while keeping you in the suburb you love.At Tide Constructions, we carry out lift and build under projects across Brisbane with the same standard of workmanship and project management we bring to every custom build. That means fixed-price contracts, licensed trades, clear timelines, and a dedicated Project Manager on your site from day one.

Why Brisbane Homeowners Choose Lift & Build Under

Brisbane’s housing market has made it harder than ever to upsize without overpaying. For many homeowners, particularly those in established suburbs like Camp Hill, Norman Park, Manly, and Bulimba, lifting and building under is a far more cost-effective way to gain the square metres they need.Here’s why it makes sense for so many Brisbane families:

Your kids stay in their school. Your daily routine doesn’t change. You simply end up with a better, bigger home at the end of the process.

You add significant value to your property

A well-executed lift and build under doesn’t just give you more room to live in - it adds measurable value to your asset. A new lower level with additional bedrooms, a bathroom, a living area, or even a self-contained granny flat can substantially lift your resale position.

You make the most of your existing structure

Many older Brisbane homes, particularly Queenslanders and post-war timber homes, are ideal candidates for this type of work. The existing roof and frame are retained, and the lower level is built fresh beneath it.

Lifting a home and building underneath it is a specialist task. It requires careful structural assessment, the right certifications, and a builder who knows how to coordinate multiple trades without cutting corners. That’s exactly what we do.

Structural Assessment & Design: Before any work begins, we assess your existing home and block to confirm suitability. We work alongside engineers and building designers to develop a plan that works for your block, your budget, and your council's requirements.

Council Approvals & Certifications: Navigating local council requirements and building approvals in Brisbane can be complex. Our team handles the paperwork and liaises with certifiers on your behalf so nothing gets missed and no unnecessary delays occur.

The Lift: Your home is carefully lifted by a licensed house-raising contractor. This is a precise process and one that we oversee closely. Once raised to the correct height, the structure is secured while the lower level is constructed beneath it.

Building the Lower Level: With your home safely liftd, our team gets to work on the new lower level. This can include additional bedrooms, bathrooms, a laundry, storage, a garage, a living room, or a fully self-contained granny flat, whatever suits your family's needs and your block's setbacks.

Reconnecting & Finishing: Once the structural and building work is complete, your home is lowered onto its new base. Internal and external finishes are completed, and the home is tied together so the old and new feel smooth.

Handover: Before keys are handed over, our director personally inspects every detail. We don't hand over a home until it meets our standards.

This type of project suits homeowners who:

Own a timber or chamferboard home on stumps with enough height clearance

Want to add bedrooms, a home office, a teenager's retreat, or a granny flat

Are looking to increase the rental yield or capital value of their property

Want to stay in their suburb without the cost of buying a larger home

Have a block that doesn't suit a traditional extension or second storey

If you’re not sure whether your home is suitable, we’ll give you an honest assessment upfront.

How long does a lift and build undertake in Brisbane?

Most lift and build under projects in Brisbane take between 6 and 12 months, depending on the scope of work and council approval timeframes.

Will I need to move out during the build?

In most cases, yes, the lifting and initial construction phase typically requires the home to be vacated for safety reasons. We'll confirm this during your initial consultation.

Do I need council approval to lift and build under in Brisbane?

Yes, a building approval and development application are generally required. Tide Constructions manages this process on your behalf.

How much does a lift and build under cost in Brisbane?

Costs vary depending on the size of the home, the scope of the lower level, and site conditions. We provide a detailed fixed-price proposal once the design and engineering are finalised.

Is my timber Queenslander suitable for lifting?

Most traditional timber homes on stumps are suitable candidates, but a structural assessment is required to confirm this for your specific property.
