Home builders in Thornlands
Construction leads every industry in Australia for insolvencies. Before you hand anyone a deposit in Thornlands, we check their licence with QBCC, sight their insurance, confirm they are still trading — and match you to the one who actually builds on blocks like yours.

Why this is harder than it looks in Thornlands
- A current licence tells you nothing about solvency
External administrators lodged 2,361 initial reports for construction companies in 2024–25 — more than any other industry in the country (ASIC Insolvency Statistics, Series 3.1). Every one of those companies held a valid licence the day before. The certificate on the wall says they are permitted to build. It does not say they can pay their framer on Friday.
- Thornlands is not a generic block
Mapped here: 3 residential zones, 6 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 Thornlands regularly already know which of these reach which streets.
- "Get three quotes" sells you, not the builder
The standard model charges builders per enquiry and sends the same one to several of them. You are the product, the fastest caller wins, and nobody in that chain has checked whether any of them is solvent. We do not sell enquiry data — not to a panel, not to a lead broker, not ever.
The mechanism
Four checks, before anyone reaches you
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 Thornlands
Confirmed with the builder against the suburbs they genuinely service — not a radius drawn on a map.
What you are dealing with in Thornlands
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 None mapped 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.

Overlay families mapped in each suburb we have read in this region. More mapped controls generally means more assessment before you can price a build.
Builders serving Thornlands
What building in Thornlands actually involves
Thornlands contains a declared Priority Development Area — Southern Thornlands. That single fact separates it from every other Redlands suburb we have mapped, because development inside a PDA is assessed under the PDA development scheme rather than under the council's planning scheme. Two blocks in the same suburb, a street apart, can be assessed under two different instruments by two different bodies.
What a Priority Development Area changes
Inside the PDA, the Redland City Plan's zones and overlays are not the operative controls — the PDA development scheme is. That affects who assesses an application, what it is assessed against, and which document you should be reading when someone tells you what is permitted. It is not inherently better or worse than a council assessment; it is different, and the difference is invisible if you assume the City Plan applies everywhere in the suburb. Before any design work, establish whether the land is inside the declared PDA. It is a boundary question with a clear answer.
Twenty-one square kilometres of mostly greenfield land
At 21.65 km², Thornlands is nearly twice the size of Cleveland and much of it is land in development rather than settled suburb. That brings the estate questions, and they come from the contract of sale rather than from any planning search: is the lot titled, what is the soil classification for this lot rather than the estate average, what design covenants apply to facade materials, roof pitch and fencing, is there a required build timeframe, and is a particular builder panel imposed. Those constraints are frequently tighter than the planning ones and they are the ones buyers discover last.
Storm tide mapping in two dated extents
The City Plan maps a 2016 Storm Tide Inundation Area and a 2016–2100 Storm Tide Inundation Area, and Thornlands intersects a high hazard storm tide area. The two dated extents mean different things — present-day exposure against exposure allowing for change to 2100 — and on greenfield land near the bay margin the second frequently reaches further inland than buyers expect. Which extent applies to a lot is a question for the lot, not the estate.
Erosion prone land at the margin
Part of Thornlands sits inside Queensland's erosion prone area, the coastal setback measured from the shoreline with allowance for sea level rise. It governs where a dwelling may sit. On a large suburb most lots will be well clear of it; on the ones that are not, it constrains the envelope before the builder is chosen.
Very High potential bushfire intensity
Very High, High and Medium Potential Bushfire Intensity are all mapped in Thornlands. On land at the edge of development, blocks backing onto retained vegetation commonly rate higher than interior lots in the same release — so the Bushfire Attack Level is a lot-level answer, not an estate-level one. It drives glazing, screening, decking and subfloor treatment, and the assessment belongs before a facade is chosen from a brochure.
No acid sulfate soils recorded, and landslide graded M and L
Our mapping records no acid sulfate soil features in Thornlands, which removes a common coastal earthworks step. The landslide hazard overlay is mapped in grades M and L; it will not reach most of this terrain, but the grade is worth checking on any lot with fall.
What to establish first in Thornlands
Whether the land is inside the Priority Development Area, because that decides which scheme applies and who assesses. Then, on estate land, the covenants and the lot's own soil classification. Then the storm tide extent and the bushfire rating, both at the lot rather than the release.

Questions about building in Thornlands
What is the Southern Thornlands Priority Development Area?
A declared PDA covering part of Thornlands. Development inside it is assessed under the PDA development scheme rather than the Redland City Plan, so the zones and overlays that apply elsewhere in the suburb are not the operative controls there.
How do I know whether my block is in the PDA?
It is a boundary question with a clear answer, and it should be settled before any design work. Two blocks a street apart in Thornlands can be assessed under different instruments by different bodies.
What should I check on a Thornlands estate lot?
Whether the lot is titled, the soil classification for that lot rather than the estate average, the design covenants on facade materials, roof pitch and fencing, any required build timeframe, and whether a builder panel is imposed. These come from the contract of sale.
Will my bushfire rating match the rest of the estate?
Not necessarily. Very High, High and Medium Potential Bushfire Intensity are all mapped in Thornlands, and lots backing onto retained vegetation commonly rate higher than interior lots in the same release. The Bushfire Attack Level is assessed at the lot.
Does storm tide reach inland parts of Thornlands?
It can. Two dated extents are mapped — a 2016 area and a 2016–2100 area — and the second frequently reaches further inland than buyers expect on greenfield land near the bay margin. Check which extent applies to the specific lot.
How this works
- 01Tell us about the build
Six questions, about three minutes.
- 02We match it against Thornlands
Against the 3 residential zones mapped here, 6 overlay families, bushfire-prone land, growth-area status — and against which builders hold the right licence class for it, have done it before, and actually work under Redland 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.
No catch
What you are agreeing to
- Nothing. There is no contract with us, no account to create, no card, and nothing to cancel.
- No obligation to use whoever we recommend. Take the name and the reasoning and do what you like with it, including nothing.
- No phone number needed to start. Give us one if you want to be called; otherwise we write.
- One builder contacts you, not six. And only after you have seen the brief and said yes.
- Your details go to that builder and nobody else. Never sold, never auctioned, never shared with a panel.
- If we have nobody in Thornlands, we say so. That is a real answer we give, and the empty builder list above is the proof we mean it.
