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

Why this is harder than it looks in South Turramurra
- South Turramurra is not a generic block
Mapped here: 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 South Turramurra 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 South Turramurra actually involves
South Turramurra returns no heritage records at all — in Ku-ring-gai, a council where neighbouring suburbs map dozens or hundreds. For a knockdown rebuild that single fact changes the starting position more than any other on this page.
An empty heritage layer, in this council
Across much of Ku-ring-gai the listing search is the first and most consequential step: a heritage item on the title can end a rebuild in the form imagined, and in several nearby suburbs the odds of finding one are real.
Here the layer was queried and returned nothing. No items, no conservation areas, no archaeological listings, no landscape protection. That is a result rather than a gap, and it means the constraint that dominates this council's pages does not arise.
What it does not remove is the ordinary development assessment, or the tree provisions, which sit in Ku-ring-gai Council's development control plan rather than on the heritage layer — and in a suburb this leafy those provisions are not incidental.
Controls that need no second look
The height is 9.5 m on all 46 parcels the layer returns, with the range running 9.5 m to 9.5 m. The floor space ratio of 0.3:1 covers 40 of 59 parcels.
Multiply the land by 0.3 for the permitted floor area, every level counted. The pattern across this council applies here too: the blocks are generous — 900–999 m² on 41 parcels and 1,000–1,999 m² on 18 — and the ratio is what limits the house rather than the land.
One zone, and no subdivision prospect
R2 Low Density Residential is the only zone mapped. With minimums of 900 m² and above across both bands, a split will generally not be available on a typical title — worth establishing from the title before an offer if that was part of the reasoning.
Six bushfire features along the river
The mapping covers buffer, vegetation category 1 and vegetation category 2, following the Lane Cove River, Peppermint Creek and Water Dragon Creek. Six features means most of the suburb sits outside the mapping.
Where it reaches a block, category 1 is present and the land falls toward the river — slope contributes to the Bushfire Attack Level alongside the vegetation, so a block on the fall can rate more steeply than one on the flat with similar planting nearby. Commission the assessment where the mapping applies and treat its asset protection zone as a siting input.
One acid sulfate feature
A single acid sulfate soil feature is mapped on the low ground. Low odds, binary at an address, and engaged only below the trigger depth — though a lower level cut into falling ground reaches that depth sooner than a slab on the level.
What to establish on a South Turramurra block
The 0.3:1 arithmetic against the brief, because with heritage absent and the height settled it is the control that actually decides the house. Then the development control plan for the tree provisions, which in this suburb do real work. Then the bushfire position if the block falls toward the river. The heritage search closes immediately, and the zone and height need no checking. Flood sits with Ku-ring-gai Council.
What you are dealing with in South Turramurra
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 checked Held in each council's own Flood Planning Map rather than in a statewide layer
- Heritage None mapped Impact statement; limits demolition, form and materials.
- Slope Not checked Published by individual councils rather than as a statewide layer
- Soil Acid sulfate Below trigger depth: management plan, treatment, disposal.
- Density controls 1 zone · 9.5m · 0.3:1 What may be built, and how much. Set parcel by parcel.

Worth knowing before you budget
- Building height
The most common maximum building height mapped here is 9.5m (46 of 46 mapped parcels). No other height control covers a meaningful share of the suburb.
- Floor space ratio
A floor space ratio of 0.3:1 applies to most of the mapped parcels here (40 of 59). On an 800 m² block that is about 240 m² of floor area, every level counted.
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 NSW Fair Trading's own public register — number, class and status, with the date we looked recorded.
- 02 · Insurance
Public liability plus whatever warranty or indemnity cover NSW 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 South Turramurra
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
Seven questions, about three minutes.
- 02We match it against South Turramurra
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 Ku-ring-gai 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.
What you get, and what it costs you
- One builder, not a list
We read your brief against what is actually mapped in South Turramurra — bushfire-prone land, acid sulfate soils — and against which builders hold the right licence class, have built under these constraints before, and genuinely work under Ku-ring-gai Council. 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 South Turramurra 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 South Turramurra 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 South Turramurra, 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 South Turramurra is that quotes are only comparable when they assume the same things — and with bushfire-prone land 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 South Turramurra
Does South Turramurra really have no heritage listings?
None. The layer was queried and returned nothing — no items, no conservation areas, no archaeological listings, no landscape protection. In Ku-ring-gai, where neighbouring suburbs map dozens or hundreds, that changes the starting position for a rebuild more than anything else on the page.
So are there no controls on what I build?
There are. The ordinary development assessment still applies, and the tree provisions sit in Ku-ring-gai Council's development control plan rather than on the heritage layer — in a suburb this leafy those are not incidental.
How much house can I build?
Multiply the land area by 0.3 — the ratio covers 40 of 59 mapped parcels. The blocks are generous at 900–999 m² and 1,000–1,999 m², so as across this council it is the ratio rather than the land that limits the house.
Can I subdivide here?
Generally not. R2 is the only zone and both lot bands sit at 900 m² and above, so a split will usually not be available on a typical title. Establish it from the title before an offer if that was part of the reasoning.
Is bushfire a concern?
On part of the suburb. Six features are mapped along the Lane Cove River, Peppermint Creek and Water Dragon Creek, so most blocks sit outside — but category 1 is present and the land falls toward the river, and slope contributes to the rating alongside the vegetation.
What height can I build to?
9.5 m, on all 46 parcels the layer returns, with no variation in the range. It does not need checking at the address.

Named watercourses in South Turramurra
3 named watercourses are mapped in South Turramurra. On any individual block the question is which of them is nearest, because that is what the setback is offset from and what the flow path follows.
- Lane Cove River
- Peppermint Creek
- Water Dragon Creek
Read from the NSW Water Theme, which maps gazetted watercourses only. A constructed channel or a stormwater drain is not in this list and can still carry water across a block.
