Home builders in Ashby
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 Ashby 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 Ashby. Then one name and the reasoning behind it — or a straight no.
- Costs you nothing, ever
- No obligation to use them

Why this is harder than it looks in Ashby
- Ashby 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 Ashby 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 Ashby actually involves
Ashby sits inside East Wanneroo Cell 1, and its governing document is a cell structure plan. The cell system is a piece of Western Australian planning vocabulary worth knowing, because it changes who pays for what.
What a development cell is
East Wanneroo was divided into numbered cells, each covering a defined area, each with its own structure plan and its own cost-sharing arrangement. The logic is that the roads, drainage, public open space and other infrastructure a new area needs benefit every landowner in it — so the costs are pooled across the cell and shared in proportion, rather than falling on whoever happens to develop first.
For a buyer the practical consequence is that land inside a cell may carry an infrastructure cost obligation attached to development, separate from the price of the land and separate from the cost of building. It is not a hidden charge — it is documented in the cell arrangements — but it is a line item that does not appear on any overlay map, and people do miss it.
Ask the question in the right form
Not "are there fees" but: which cell, what is the current contribution rate, and when is it payable. The City of Wanneroo administers it and the answer is specific to the parcel.
Two activity centre codes
R-AC3 and R-AC4 are mapped alongside R20, R30, R40 and R80. R-AC codes are not densities you can read — they set the standard by reference to an activity centre plan, so where one applies the plan is the operative document and the code table is not the answer.
That R80 sits in the same suburb as R20 is worth noting separately: the range is fourfold, and on 1.4 km² the boundaries between them are close together.
Urban development land
An Urban development zone is mapped alongside Residential. On that land the density comes through a structure plan rather than the scheme, so it is not yet fixed by the code table.
Bushfire
Three bushfire-prone features are mapped. Worth an address check, and worth asking how recent the assessment is on land still being released.
What to establish first in Ashby
The cell contribution — which cell, what rate, when payable — because it is a real cost that no map shows. Then whether an R-AC code applies and which plan it refers to. Then the zone.
What you are dealing with in Ashby
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–R80 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 Ashby
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 Ashby
Against the 2 residential zones mapped here, 2 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 City of Wanneroo.
- 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 Ashby — 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 Wanneroo. 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 Ashby 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 Ashby 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 Ashby, 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 Ashby 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 Ashby
What is a development cell?
A defined area with its own structure plan and cost-sharing arrangement. Roads, drainage and public open space benefit every landowner in the cell, so costs are pooled and shared in proportion rather than falling on whoever develops first.
What does that mean for me?
Land inside a cell may carry an infrastructure cost obligation attached to development — separate from the land price and the build cost. It is documented, but it appears on no overlay map.
How should I ask about it?
Not "are there fees" but: which cell, what is the current contribution rate, and when is it payable. The City of Wanneroo administers it and the answer is specific to the parcel.
What are R-AC3 and R-AC4?
Activity centre codes. They are not densities you can read — they set the standard by reference to an activity centre plan, so where one applies the plan is the operative document.
How wide is the density range?
Fourfold, from R20 to R80, across 1.4 km² — so the boundaries between them are close together.
