A useful brisbane renovation starts with the cost bands: bathrooms around $22,000 to $35,000, kitchens $25,000 to $60,000, extensions and full home projects from $150,000. Any building work over the $3,300 QBCC threshold must use a licensed builder, and structural changes usually need Brisbane City Council approval. Comparing quotes means checking licence status, scope, approvals and timeline together, not price alone.
For local buyers, brisbane renovation comparison here is how to weigh the options without getting lost in the detail.
Brisbane Renovation Comparison Explained
Most owners comparing renovation options in Brisbane weigh the same three variables: budget, the licensed trades available, and whether council approval applies. A brisbane renovation is rarely a single decision. It is a chain of choices about scope, finishes and timing, and each choice changes the next one.
The practical way to compare is to line up the project types side by side, check that every builder quoting holds a current QBCC licence for the right class of work, and confirm which approvals Brisbane City Council will expect before design is locked in. Brisbane has seen more than $1.08 billion in approved renovations, so strong demand also means quality trades book out early.
Cost bands that shape the decision
Pricing varies with scope, finishes and the age of the home, but Brisbane work sits in fairly predictable bands. Heritage and Queenslander projects tend to price higher because timber framing, restumping and character detailing add labour.
- Bathroom renovation: $22,000 to $35,000+, driven by waterproofing, tiling and plumbing relocation.
- Kitchen renovation: $25,000 to $60,000+, driven by cabinetry, benchtops, appliances and layout change.
- House extension: from $150,000, with footings, roofing, structural and council work the main drivers.
- Full home renovation: from $150,000+, depending on scope, finishes and heritage or Queenslander factors.
These are planning figures, not quotes. A written, itemised quote from a site inspection is the only reliable basis for your own brisbane renovation.
Licensing and approvals that decide who you can hire
In Queensland, building work valued above $3,300, including labour and materials, must be performed by a QBCC-licensed contractor, and work over that figure generally requires a written contract. A licensed builder carries the right insurance, is covered by the statutory home warranty scheme on eligible residential work, and can be held to account through the QBCC if something goes wrong.
Not every job needs development approval, but many structural changes do. Internal cosmetic work such as a like-for-like kitchen or bathroom refresh is often building-approval territory only, while extensions, raising or lowering a Queenslander, removing walls, or altering a protected home usually need planning approval as well. Because Brisbane has extensive character-protection overlays, confirm requirements with the Council and a licensed builder before design is finalised.
Renovate, extend or rebuild
The biggest fork in any comparison is whether to work within the existing footprint or change it. Renovating within the footprint costs less and involves fewer approvals, but space stays fixed. Extending or raising adds room where the block allows it, at higher cost and with council assessment. A knockdown rebuild suits a failing or unsuited structure, but carries the highest cost, the longest timeline, and character rules that may block it.
This framing applies most directly to owners in suburbs such as Paddington, New Farm, Bulimba, Toowong and West End planning a kitchen or bathroom upgrade, Queenslander owners weighing raising, extending or restoring heritage detail, and buyers in Moreton Bay, Logan, Redlands or Ipswich budgeting a full home project.
Bringing the comparison together
Once the cost bands, licence checks and approval questions are answered, the decision usually comes down to timeline and risk. Bathrooms run to a few weeks, kitchens several weeks, and extensions or full home projects commonly run to a few months once approvals are in place. Quotes are typically returned within about 48 hours of a site visit, so gathering two or three itemised quotes early is the simplest way to test whether your budget and the market line up.
Keep every quote on the same scope, verify the QBCC licence class, and confirm approval responsibilities in writing before signing a contract.
- Set the brief and budget. Define the rooms, must-haves and a ceiling figure before calling anyone.
- Arrange site visits and quotes. A licensed builder inspects the home, measures up and returns a written, itemised quote.
- Contract and approvals. Sign a QBCC-compliant contract and lodge building or planning approval with Brisbane City Council where required.
- Build and handover. Demolition, structural work, services and finishes proceed in sequence with inspections, then final inspection and certification.
| Option | Best when | Trade-off |
|---|---|---|
| Renovate within the footprint | Layout works, you want updated finishes | Lower cost and fewer approvals, but space is fixed |
| Extend or raise | You need more space and the block allows it | More cost and council assessment, keeps the home |
| Knock down and rebuild | The structure is failing or unsuited | Highest cost, longest timeline, character rules may block it |
Common questions
Do I need a QBCC-licensed builder for a small renovation? If the building work is valued over $3,300 including labour and materials, yes. Below that figure a licence is not mandatory, but a licensed builder still gives you the statutory protections.
How long does a renovation take in Brisbane? A bathroom can be a few weeks, a kitchen several weeks, and an extension or full home renovation commonly runs a few months once approvals are in place.
How do I know whether council approval is needed? Internal cosmetic work often needs only building approval, while extensions, raising a Queenslander, removing walls or altering a protected home usually need planning approval as well. Confirm with Brisbane City Council and a licensed builder.
