Experience 20+ years raising and building under Brisbane homes
Raising and building under your Brisbane home adds significant living space underneath your existing house, often without extending the footprint or changing the street-facing character of the house. If you’ve heard there are more stages involved than expected, that’s a fair warning, and it’s exactly why managing the whole process under one team matters.
Bishop Construction has raised and built under homes across Brisbane for over 20 years, family-owned and led by Barney since 2004. QBCC Licence 1074234, full member of Master Builders QLD, and an approved builder on the Queensland Government’s Resilient Homes Fund panel for flood-affected homes.
How Raising And Building Under Your Home Works, Stage By Stage
The process starts with a free on-site consultation by our team to assess your existing house, discussing your vision, and breaking down cost and what’s achievable. From there, structural engineering, the lift itself, and the build-under construction follow as connected stages, all managed by one team.
The new level created underneath your house adds genuine living space once the build-under work is done, whether it becomes a garage, a rumpus room, or an everyday living zone for the family. Design for this new level of the house starts alongside the structural work, not after, because the house’s footings and the lift affect what the finished design can support. Planning ahead also covers council approvals, which work differently on new raise and build under projects than on standard renovations, and leaving them too late can slow the whole build.
Because one team manages the assessment, the structural planning, the lift, and the build-under construction, there’s a single point of contact through each stage of the project rather than separate trades handling separate projects and quoting separate costs. This keeps cost more predictable too: the same team pricing the lift also prices the level underneath, so you end up with one cost figure to work with rather than two.
Raise and build under projects suit houses on sloping blocks in Brisbane where standard renovations and extensions aren’t possible, since there’s often no other way to add a new living space without extending the footprint. It’s worth raising with the team early in your planning, alongside any other renovations you’re considering for the house, since the design of one stage can shape the design of the next.
What You Can Add Underneath A Raised Brisbane Home

A new space created underneath a raised house commonly becomes additional bedrooms, a bathroom, a living area, or a combination of these, effectively doubling usable floor area without extending the home’s footprint.
Because the new space sits beneath an existing house, plumbing and electrical often just extend down from what’s already there rather than starting fresh, which keeps cost lower than other renovations that require new footings. Ceiling height is the main technical constraint on these projects, since a lift needs enough clearance before the space underneath the house counts as habitable rooms rather than storage.
Staging the work also affects cost. Some homeowners fit out one or two rooms straight away and leave the rest for later renovations, spreading the spend rather than finishing every room in one project. Others use the space to house a self-contained unit for family, which changes the layout and the projects that follow, such as separate access or a second bathroom, and can influence future renovations elsewhere in the house.
Talking through similar projects on comparable blocks nearby gives a realistic sense of cost before committing to a design for your own Brisbane house.
Raise And Build Under Vs A Second-Storey Extension
| Option | Best For | Key Consideration |
|---|---|---|
| Raise and build under | Queenslanders and homes on stumps | Adds space below without changing the roofline |
| Second-storey extension | Homes not suited to raising | Adds space above, changes the height and streetscape |
Managing Structural, Drainage And Access Challenges During A Raise
Structural engineering, drainage and site access all need to be assessed before a raise begins, particularly on sloping or difficult sites. We manage this planning during the consultation and design stage, so it’s built into your fixed-price quote.
Raising Your Home Through The Resilient Homes Fund
Bishop Construction is an approved builder on the Queensland Government’s Resilient Homes Fund panel, which supports flood-affected homeowners raising their properties. We can help guide flood-affected clients through the funding and paperwork alongside the build itself.
Flood-affected clients can discuss eligibility, paperwork and the build process with the same team managing the project.
What A Raise And Build Under Project Typically Costs

Cost depends on the size of the home, the height of the lift, structural requirements and what the build-under space is used for. A free on-site consultation lets us give you a realistic, fixed-price estimate for your specific home.
What Shapes The Cost
The quote is based on your actual house and site rather than a generic allowance.

Common Questions About Raising And Building Under In Brisbane
Do I need to move out during the raise?
In most cases, yes, for safety during the structural lift and construction phase.
Can I use the Resilient Homes Fund for this project?
If your property is flood-affected and eligible, yes, and we can help guide you through it.
Will building under change my home’s street appearance?
Generally the street-facing view stays largely the same, since the raise adds space below rather than altering the visible roofline.
