Home builders in Cornubia
A builder’s licence is permission to trade. It is not a solvency test. 2,361 construction companies entered external administration last financial year, more than any other industry in the country — and no regulator checks whether the one quoting your Cornubia job can still pay its framer on Friday. We run the Four-Point Builder Check™: licence with QBCC, insurance sighted, still trading, and genuinely working in Cornubia. Then one name and the reasoning behind it — or a straight no.

Why this is harder than it looks in Cornubia
- Cornubia is not a generic block
Mapped here: 3 residential zones, 10 overlay families, bushfire-prone land. A builder who prices the house and discovers the site is a builder whose quote moves — and the variations land on you, not on them. The ones who work Cornubia regularly already know which of these reach which streets.
- A current licence tells you nothing about solvency
Every one of the companies behind that figure held a valid licence the day before it failed. The certificate on the wall says they are permitted to build. It does not say they can pay their framer on Friday.
What building in Cornubia actually involves
Cornubia carries a waterway corridors and wetlands overlay mapped over wetlands. Wetland boundaries are set by where water sits, not by survey lines, which makes this one of the few controls where the right question is not "is my lot inside it" but how close are the works.
Proximity, not inclusion
A wetland control protects a hydrological system, and a system does not stop at a cadastral boundary. So the assessment looks at what the works do to it: filling that changes where water sits, drainage that redirects it, clearing at the margin that removes the vegetation holding it, and earthworks close enough to alter the water table. A parcel wholly outside the mapped wetland can still trigger an assessment if what is proposed reaches it, and a parcel partly inside it may be perfectly buildable on the dry portion. The practical move is to get the mapped extent against your survey early, then design the platform, the driveway and the drainage around it rather than drawing a house first. Cornubia Forest Nature Refuge sits within the locality.
Three flood layers, one of them temporary
Flood is mapped three ways: a flood assessment area under TLPI 1/2024, a high flow area, and flood risk areas. The first of those is a Temporary Local Planning Instrument — it carries force now and it has an end date, so ask which instrument your assessment is being made under. High flow is the restrictive layer: it marks where water moves with force, and obstruction rather than floor height is the concern there.
Rural Residential as the dominant zone
Rural Residential is recorded as dominant, with Low Density Residential and Low-Medium Density Residential also mapped across 15.12 km². On rural residential land the cost drivers move away from the dwelling and onto servicing — the wastewater system and the area it needs, water supply, the distance to a power connection and the driveway. Combined with a wetlands overlay, the wastewater disposal area becomes the constraint to solve first, because it needs space and it cannot sit near the wetland.
Landslide with steep slopes, and a noise corridor
A landslide hazard and steep slopes overlay is mapped — pairing the two in one instrument captures ground that is awkward to build on without being unstable, so triggering it is not in itself a landslide finding. A transport noise corridor for a State-controlled road also applies, which sets noise criteria a dwelling has to meet through glazing, wall construction and ventilation.
Heritage, bushfire and soils
A heritage areas overlay is mapped. Bushfire is mapped in the Logan Planning Scheme 2015's own overlay, because in Queensland the scheme is the only source for it. No acid sulfate soils are mapped in Cornubia.
What to establish on a Cornubia block
The mapped wetland extent against your survey, and then where the wastewater area, platform and driveway can go — in that order. Then which flood layer applies and under which instrument. Then the slope position and whether the noise corridor reaches the lot.
What you are dealing with in Cornubia
Six things a builder prices differently. This is the suburb-level picture — which of them reaches your block is an address check.
- Bushfire Mapped BAL assessment; glazing, decking and screening spec.
- Flood Mapped Sets a minimum floor level. Flood report first.
- Heritage 1 record Impact statement; limits demolition, form and materials.
- Slope Mapped Geotech report before footings can be priced.
- Soil None mapped Below trigger depth: management plan, treatment, disposal.
- Density controls 3 zones What may be built, and how much. Set parcel by parcel.

The mechanism
The Four-Point Builder Check™
Every one of them is something you could do yourself. What we sell is that it has been done, dated and published — and repeated on a schedule, because a check that happened once is worth nothing.
- 01 · Licence
Looked up on QBCC's own public register — number, class and status, with the date we looked recorded.
- 02 · Insurance
Public liability plus whatever warranty or indemnity cover QLD requires. Sighted by us, not self-declared on a form.
- 03 · Still trading
Solvency re-checked on a schedule. A licence stays current right up until the day a company fails.
- 04 · Works in Cornubia
Confirmed with the builder against the suburbs they genuinely service — not a radius drawn on a map.
How this works
- 01Tell us about the build
Six questions, about three minutes.
- 02We match it against Cornubia
Against the 3 residential zones mapped here, 10 overlay families, bushfire-prone land — and against which builders hold the right licence class for it, have done it before, and actually work under Logan City Council.
- 03One recommendation, with the reasoning
Not six quotes to sift. We negotiate on your behalf; you deal with the builder directly. Builders pay us, only once you sign.
What you get, and what it costs you
- One builder, not a list
We read your brief against what is actually mapped in Cornubia — 3 residential zones, 10 overlay families, bushfire-prone land — and against which builders hold the right licence class, have built under these constraints before, and genuinely work under Logan City Council. You get one name and the reasoning in writing.
- Or a straight no
The same business day you get one of two things: our recommendation, with the reasons — or a plain email saying we have not got a builder in Cornubia we would put our name to yet, and what we are doing about it. No drip campaign, no being passed around.
- It costs you nothing, ever
The builder pays us, and only if you sign with them. You are never charged, and you are never under any obligation to use the builder we name. How the fee works.
We are not a builder, we do not manage your build, and we do not hold your money.
Fair questions before you send anything
- You have no builders listed in Cornubia yet. What use is that?
A fair question, and the honest answer is that a list is not what we do. We do not publish a builder until the licence is checked, the insurance is sighted and we have confirmed they are still trading — so an empty list here means we have not finished that work in Cornubia, not that we cannot help. Send the brief and we go and find one for your block. If we cannot, you get told that, the same day, rather than being added to a mailing list.
- Why not just get three quotes myself?
You can, and for a simple job you probably should. The difficulty on a block in Cornubia is that quotes are only comparable when they assume the same things — and with 3 residential zones mapped here, two builders can price the same house against different assumptions about the site and both be quoting honestly. Sorting that out is the part we do.

Questions about building in Cornubia
How does the wetlands overlay affect a build?
Wetland boundaries are set by where water sits, not by survey lines, so the question is not whether your lot is inside it but how close the works are. It looks at filling that changes where water sits, drainage that redirects it, clearing at the margin, and earthworks close enough to alter the water table.
Can a lot outside the wetland still be affected?
Yes. A parcel wholly outside the mapped wetland can trigger an assessment if what is proposed reaches it, and a parcel partly inside may be perfectly buildable on the dry portion.
What should I do first?
Get the mapped extent against your survey, then design the platform, driveway and drainage around it — rather than drawing a house first.
How is flooding mapped in Cornubia?
Three ways: a flood assessment area under TLPI 1/2024, a high flow area, and flood risk areas. The TLPI is a Temporary Local Planning Instrument — it carries force now and has an end date, so ask which instrument your assessment is made under.
What zone is Cornubia?
Rural Residential is dominant, with Low Density and Low-Medium Density Residential also mapped. On rural residential land the cost drivers move onto servicing, and with a wetlands overlay the wastewater disposal area is the constraint to solve first — it needs space and cannot sit near the wetland.
What does the landslide and steep slopes overlay cover?
Both in one instrument, which captures ground awkward to build on without being unstable — so triggering it is not in itself a landslide finding. A transport noise corridor for a State-controlled road also applies.
