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

Why this is harder than it looks in Mosman Park
- Mosman Park is not a generic block
Mapped here: 2 overlay families, 44 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 Mosman Park 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 Mosman Park actually involves
Fourteen R-Code values, four of them dual
Mosman Park maps R12.5, R12.5/25, R15, R15/25, R17.5, R20, R20/25, R25, R30, R40, R50, R60, R80 and R160 across 4.35 km² — fourteen distinct code values, four of which are dual codes.
The dual codes are the reason this page leads with the R-Codes rather than the heritage. A dual such as R12.5/25 means a base density of R12.5 with R25 available where the scheme's criteria are met — and those criteria are written in the scheme text, not on the map.
The practical failure mode is buying on the higher number. A site advertised as "R25 potential" may be R12.5 in fact, with the R25 conditional on requirements the buyer has not read. Establish the base code, the higher code and the conditions attached, in writing, from Town of Mosman Park before an offer.
Two Special Control Areas
SCA — development areas and SCA — local planning areas both apply. Special control areas carry provisions additional to the zoning, and on land near the river and the highway they are where the real constraints on built form usually sit.
Two named structure plans
The 9–15 McCabe Street Structure Plan and the Lot 2 (140) Stirling Highway Precinct Structure Plan apply to land here. Where a structure plan covers a site it governs subdivision and development on that land, and it can depart from the scheme's general provisions.
Heritage, and bushfire
44 heritage records are mapped — a moderate layer beside the code complexity, and a straightforward address check.
Part of Mosman Park is mapped as bush fire prone. Where it reaches a block, a Bushfire Attack Level assessment sets the construction standard, and on a riverside or elevated site that is worth establishing before a design rather than after.
What you are dealing with in Mosman Park
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 44 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–R160 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 Mosman Park
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 Mosman Park
Against the 1 residential zone mapped here, 2 overlay families, bushfire-prone land, 44 heritage records — and against which builders hold the right licence class for it, have done it before, and actually work under Town of Mosman Park.
- 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 Mosman Park — 2 overlay families, 44 heritage records, bushfire-prone land — and against which builders hold the right licence class, have built under these constraints before, and genuinely work under Town of Mosman Park. 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 Mosman Park 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 Mosman Park 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 Mosman Park, 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 Mosman Park is that quotes are only comparable when they assume the same things — and with 2 overlay families 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 Mosman Park
How many R-Code values are mapped in Mosman Park?
Fourteen — R12.5 through R160 — four of which are dual codes.
What is a dual code?
A base density with a higher one available where the scheme's criteria are met. R12.5/25 means R12.5 in fact, with R25 conditional on requirements written in the scheme text rather than shown on the map.
What is the failure mode?
Buying on the higher number. A site advertised as 'R25 potential' may be R12.5 in fact. Establish the base code, the higher code and the conditions attached, in writing, before an offer.
What do the Special Control Areas do?
They carry provisions additional to the zoning. On land near the river and the highway they are usually where the real constraints on built form sit.
Do structure plans apply?
Two — the 9–15 McCabe Street Structure Plan and the Lot 2 (140) Stirling Highway Precinct Structure Plan. Where one covers a site it governs subdivision and development and can depart from the scheme's general provisions.
Is Mosman Park bushfire prone?
Part of it is mapped as bush fire prone. Where it reaches a block a Bushfire Attack Level assessment sets the construction standard, worth establishing before a design on a riverside or elevated site.

Have you had an application through Town of Mosman Park 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?
