House raising in Queensland: costs, reasons and how approval works
In Victoria, raising a house is unusual. In Queensland, it's a way of life — the high-set Queenslander was designed to be lifted, and whole streets in Bundaberg, Maryborough and Brisbane have gone up a level after the floods. Here's the full picture for 2026.
Why Queenslanders raise
- Flood resilience. After the 2011 and 2013 floods (the Burnett through North Bundaberg, the Mary through Maryborough — twice again in 2022), raising the habitable floor above the defined flood level became the standard fix. Some council and government resilience programs have part-funded raises in flood areas.
- Legal-height rooms underneath. The National Construction Code requires a ceiling height of about 2.4m for habitable rooms (2.1m for utility spaces). Raise a high-set home to legal height, build in underneath, and you roughly double the floor area on land you already own — far cheaper per square metre than extending.
- Extra space and airflow. Parking, storage, a workshop, and the classic Queensland breezeway underneath.
- It pairs naturally with restumping. If the stumps are shot anyway, the marginal cost of going up while the house is on jacks is the best value the job will ever offer.
What it costs
A typical raise runs $15,000–$40,000+ on top of restumping, depending on lift height, house size and weight, and how much re-connection the services need (plumbing, electrical, gas, stairs). Building in underneath afterwards is a separate project with its own approval. Get every quote itemised: lift, new stumps/columns, services, stairs, approval and engineering.
The process
- Inspection and engineering: the frame is assessed and an engineer designs the new stump or column layout for the raised height and your soil and wind classification.
- Building approval from a certifier: in Queensland, building approval is issued by a building certifier — almost always a private certifier — under the Building Act 1975, not by a council building surveyor. Planning rules also apply: most councils allow raising without a separate planning application while the building stays under the height limit (in Brisbane, 9.5m), and flood-area blocks must meet minimum habitable floor levels.
- The lift: the house is raised on hydraulic jacks in controlled stages, new longer stumps or steel columns are installed to the engineer's design, and the house is lowered on and fixed down (cyclone-region tie-downs matter here).
- Services and stairs are extended and reconnected by licensed trades.
- Inspections and final certificate from the certifier close the approval out — keep this paperwork; it matters at sale.
Who's allowed to do it
House raising and restumping are building work under Queensland law: any contractor doing work valued over $3,300 (including materials) must hold the appropriate QBCC licence, and residential work over $3,300 must also carry Queensland Home Warranty Scheme cover — the premium is built into the contract price and paid to the QBCC before work starts.
