Home builders in Brentwood
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 Brentwood job can still pay its framer on Friday. We run the Four-Point Builder Check™: licence with Building and Energy WA, insurance sighted, still trading, and genuinely working in Brentwood. Then one name and the reasoning behind it — or a straight no.

Why this is harder than it looks in Brentwood
- Brentwood is not a generic block
Mapped here: 3 heritage records, 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 Brentwood 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 Brentwood actually involves
Brentwood is 0.89 km² — the smallest area we have published in Perth — with codes from R20 to R40 and a special code of R12.5. That last figure is the interesting one, because a code below R20 does something the standard ladder does not.
What a code below the standard setting means
R12.5 contemplates around twelve and a half dwellings per hectare — materially fewer than the R20 that functions as ordinary suburban density in Perth. In practice that means larger minimum lot sizes and a form of development the scheme is deliberately keeping low.
Where it applies, it is usually protecting something specific: an established larger-lot character, a landscape or tree canopy, or a servicing constraint. The code itself does not say which, and that is worth knowing rather than guessing — the City of Melville's scheme text is where the reason lives, and the reason tends to predict how flexible the council will be about anything that departs from it.
A narrow ladder above it
R20, R25, R30 and R40 are the standard codes mapped. That is a modest range by western-suburbs standards — no R60, no R80, no activity centre codes — so the density question here is a question of degree rather than of kind. Nothing in Brentwood is coded for apartment-scale development.
A small suburb magnifies the neighbours
At 0.89 km² almost every lot in Brentwood is close to a boundary with different coding. The code on adjoining land is therefore a more useful piece of information here than in a larger suburb, where a higher-coded pocket may be streets away rather than over the fence. It is one look at the scheme map and it is the only forward-looking information available about the street.
No structure plan
None is mapped. Where a structure plan covers land it replaces parts of the standard provisions and becomes the operative document; with none here, the codes are read straight from the scheme, and the answer for a lot does not depend on a separate plan you have to go and find.
Two bushfire features
Two bushfire-prone features are mapped across a small area. Worth an address check. Where the mapping reaches a lot, the house is built to a Bushfire Attack Level assessed on site, and that reaches glazing, screening, decking, subfloor and eaves.
What to establish first in Brentwood
The code at the address, and if it is R12.5, what the scheme says that code is protecting. Then the minimum lot size the code sets, which on a small suburb is what decides whether subdivision is available at all. Then the bushfire position.
What you are dealing with in Brentwood
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 Not mapped Sets a minimum floor level. Flood report first.
- Heritage 3 records Impact statement; limits demolition, form and materials.
- Slope Not checked No Western Australian scheme maps landslip as a special control area, and there is no statewide layer
- Soil Not checked DWER publishes acid sulfate risk as regional map sheets, not one statewide layer we can read a blank from
- Density controls 1 zone · R12.5–R40 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 Building and Energy WA's own public register — number, class and status, with the date we looked recorded.
- 02 · Insurance
Public liability plus whatever warranty or indemnity cover WA 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 Brentwood
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 Brentwood
Against the 1 residential zone mapped here, bushfire-prone land — and against which builders hold the right licence class for it, have done it before, and actually work under City of Melville.
- 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 Brentwood — 3 heritage records, bushfire-prone land — and against which builders hold the right licence class, have built under these constraints before, and genuinely work under City of Melville. 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 Brentwood 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 Brentwood 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 Brentwood, 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 Brentwood is that quotes are only comparable when they assume the same things — and with 3 heritage records 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 Brentwood
What is R12.5?
A code contemplating around twelve and a half dwellings per hectare — materially fewer than the R20 that functions as ordinary suburban density in Perth. It means larger minimum lot sizes and a form the scheme is deliberately keeping low.
Why would a code like that apply?
It is usually protecting something specific — an established larger-lot character, a landscape or tree canopy, or a servicing constraint. The scheme text is where the reason lives, and the reason tends to predict how flexible a council will be about departures.
How high do the codes go here?
R40. No R60, no R80, no activity centre codes — nothing in Brentwood is coded for apartment-scale development, so the density question is one of degree rather than kind.
Is there a structure plan?
None. The codes are read straight from the scheme, so the answer for a lot does not depend on a separate plan you have to go and find.
What decides whether I can subdivide?
The minimum lot size the code sets. On a suburb this small that is the question, and it follows directly from the code at the address.
What to ask a builder about a block in Brentwood
Each one is here because of something mapped in Brentwood. Take them to whoever quotes.
- 01
Confirm the zone at the address is Residential — and what it permits without a planning permit.
- 02
What bushfire attack level have you built to in Brentwood before, and what did it change in the glazing, decking and screening?
- 03
Have you had an application through City of Melville where a heritage control applied, and how long did the assessment take?
- 04
What R-code is this block, and what does it set for minimum and average site area per dwelling?
