Home builders in Aubin Grove
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 Aubin Grove 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 Aubin Grove. Then one name and the reasoning behind it — or a straight no.

Why this is harder than it looks in Aubin Grove
- Aubin Grove is not a generic block
Mapped here: 2 residential zones, 2 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 Aubin Grove 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 Aubin Grove actually involves
Aubin Grove carries two residential zones at once. Part of it is mapped Residential and part of it is mapped Development, under the same Cockburn Local Planning Scheme No. 3, inside 2.47 km². Those are not two flavours of one thing. They are two different routes to an approval, and which one you are on is decided by the address.
Residential: the rules are on the map
On Residential-zoned land the controls already exist. There is an R-code on the parcel, the Residential Design Codes set the site area, setbacks and open space that follow from it, and a compliant design is assessed against a standard you can read before you buy. The work is in matching a design to a known code.
Development: the rules arrive separately
On Development-zoned land the scheme defers the detail. What governs the lot is an endorsed structure plan — its layout, its densities, its staging — and the scheme map shows you none of it. Two blocks a few hundred metres apart in Aubin Grove can therefore be answered out of entirely different documents, and a builder quoting confidently off "the code in Aubin Grove" has not yet established which half of the suburb the land is in.
The practical difference is timing
What actually costs money is not what you may build but when you may start. On Residential land the sequence runs survey, design, approval, build. On Development land the plan has to be endorsed and the subdivision has to have progressed far enough for your lot to exist as a lot at all. A design commissioned against the wrong assumption is a design paid for twice.
Six other zones, including one with no zone at all
The scheme also maps Local centre, Mixed use, Public purposes, Resource and Special use land inside Aubin Grove — and a category our read returns as No zone. Land showing no zone on a local scheme map is usually land governed at a different level, most often because it is reserved under the region scheme rather than zoned under the local one. It is not unregulated; it is regulated somewhere else. If a parcel comes back this way, that is the thread to pull.
R20 to R60 across a small suburb
The coded land runs R20 to R60. A three-fold spread over 2.47 km² is tight enough that the code can change within a single street block, and it means the medium-density end is genuinely present rather than theoretical. R60 land supports a built form most buyers are not picturing as they walk a street of single houses.
Bushfire, and the fill
Three Bush Fire Prone Areas are mapped here — a light footprint for a suburb this size, following what vegetation remains rather than the streets. The other site question in Aubin Grove is the fill. Land brought to level during subdivision behaves according to the engineering that went into it, and that engineering is either documented or it is not. A soil classification tells you what the ground is; the compaction records tell you why it is that way. On a lot in the Development-zoned part of the suburb, both should be obtainable from the developer.
What to establish about an Aubin Grove address
First, which of the two zones the parcel sits in — everything else follows from that. If Residential, the R-code and the site areas it sets. If Development, the structure plan, its density and its stage. Then the zone of the adjoining land, because Mixed use and Local centre are inside this suburb. Then bushfire, then the fill.
What you are dealing with in Aubin Grove
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 None mapped 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 2 zones · R20–R60 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 Aubin Grove
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 Aubin Grove
Against the 2 residential zones mapped here, 2 overlay families, bushfire-prone land — and against which builders hold the right licence class for it, have done it before, and actually work under City of Cockburn.
- 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 Aubin Grove — 2 residential zones, 2 overlay families, bushfire-prone land — and against which builders hold the right licence class, have built under these constraints before, and genuinely work under City of Cockburn. 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 Aubin Grove 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 Aubin Grove 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 Aubin Grove, 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 Aubin Grove is that quotes are only comparable when they assume the same things — and with 2 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 Aubin Grove
Is Aubin Grove Residential or Development zoned?
Both. The suburb carries two residential zones under Cockburn Local Planning Scheme No. 3, and which one applies has to be checked against the address. It is the first question to resolve, because the rest of the process differs depending on the answer.
Why does the zone change what I have to do?
On Residential land the R-code and the Design Codes give you a standard you can read and design to now. On Development land the scheme defers to an endorsed structure plan, so density, layout and staging come from that document — and your lot may not exist as a lot yet.
What does 'No zone' mean on the map?
Usually that the land is governed at a different level — most often reserved under the region scheme rather than zoned under the local one. It is not unregulated land. If a parcel you are looking at returns this, ask the City which instrument covers it.
How dense can Aubin Grove get?
The coded land runs R20 to R60. R60 supports a materially different built form to the single houses on much of the suburb, and across 2.47 km² the code can change within a street block. Check the code on the block behind and beside yours, not just your own.
What should I ask about the ground here?
On subdivided land, ask for the site classification for your specific lot and for the compaction documentation behind any fill. The classification drives the footing design; the compaction records are what tell you whether the classification will hold up.
