Home builders in St Ives Chase
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 St Ives Chase 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 St Ives Chase. Then one name and the reasoning behind it — or a straight no.

Why this is harder than it looks in St Ives Chase
- St Ives Chase 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 St Ives Chase 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 St Ives Chase actually involves
No heritage is mapped in St Ives Chase. Not a listed item, not a conservation area, nothing. On an established north-shore suburb of substantial older houses that is a surprising result, and it is a result rather than a gap — the register was read and returned empty.
A clear register closes a question most pages leave open
Heritage is usually the control that most complicates a knockdown rebuild, because it is the one that can stop demolition outright rather than merely shape what replaces the house. Where the register is empty for a whole suburb, that risk is not reduced, it is absent: the demolition question here is a building and engineering question rather than a heritage one. Two cautions keep it honest. A blank is a statement about the mapped register, not about what a council might later list, and it says nothing about a tree, which is protected by a different instrument entirely. And it is suburb-level — the finding is that nothing is mapped anywhere in St Ives Chase, which is stronger than "nothing is mapped on your block" but is not a substitute for the certificate that confirms it.
Total uniformity in the height control
A maximum height of 9.5 m is mapped on 29 of 29 parcels — every parcel the layer covers carries the same value, with no spread above or below it. That is rarer on this site than any particular number would be, and it means the storey question is settled before an address is checked. The floor space ratio is low: 0.3:1 on 22 of 43 mapped parcels, which on a 1,000 m² block is about 300 m² of floor area with every level counted. Low ratio, generous land, two storeys — the envelope describes a large house on a large block rather than a dense one.
Two lot bands, both large
Minimum lot size is mapped in two bands and they are the same size as each other: 900–999 m² on 21 parcels and 1000–1999 m² on 21. Both are large, so the practical question is not which band but whether a holding clears the minimum at all — and because the minimum governs subdivision rather than what may be built, that is a question about dividing land rather than about building on it. R2 Low Density Residential is the only zone mapped.
Bushfire is the constraint that replaces heritage
Six bushfire-prone features are mapped, and they span Vegetation Buffer and Categories 1, 2 and 3 — all four classes from a small number of features, which is what a suburb sitting against Ku-ring-gai bushland produces. Cowan Creek and Kuring-Gai Creek are the mapped watercourses, and the bushland along them is the fuel. On a block backing onto reserve, the assessed attack level sets the construction standard and the asset protection zone has to be achievable inside the property, because the land beyond the boundary is not going to be cleared.
One acid sulfate feature, and a clear subsidence result
One acid sulfate soil feature is mapped — negligible, and relevant only to a deep excavation such as a basement or a pool. St Ives Chase sits outside every declared mine subsidence district, which is a read result from a statewide register.
Where the risk actually sits
The bushfire class and the attack level, because with heritage clear it is the control most likely to change the build specification. Then the asset protection zone, which has to fit inside the boundary. Then whether the holding clears the lot minimum, if subdivision is the plan. The height and the ratio need confirming rather than investigating.
What you are dealing with in St Ives Chase
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 (29 of 29 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 (22 of 43). 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 St Ives Chase
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 St Ives Chase
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 St Ives Chase — 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 St Ives Chase 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 St Ives Chase 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 St Ives Chase, 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 St Ives Chase 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 St Ives Chase
Is St Ives Chase heritage-affected?
No heritage is mapped at all — not a listed item, not a conservation area. On an established north-shore suburb that is surprising, and it is a result rather than a gap: the register was read and returned empty.
What does that mean for a knockdown rebuild?
Heritage is usually the control that can stop demolition outright rather than merely shape what replaces a house. Where the register is empty for a whole suburb that risk is absent, so the demolition question becomes a building and engineering one.
Any caveats on that?
Two. A blank describes the mapped register, not what a council might later list, and it says nothing about a tree, which is protected by a different instrument. And it is suburb-level — stronger than “nothing on your block”, but not a substitute for the certificate that confirms it.
What is the height limit?
9.5 m, mapped on 29 of 29 parcels — every parcel the layer covers carries the same value, with no spread. The storey question is settled before an address is checked.
How much floor area is allowed?
A floor space ratio of 0.3:1 applies to 22 of 43 mapped parcels, which on a 1,000 m² block is about 300 m² with every level counted. Low ratio, generous land, two storeys.
Is St Ives Chase bushfire-prone?
Six features are mapped but they span all four classes — Vegetation Buffer and Categories 1, 2 and 3 — which is what a suburb against Ku-ring-gai bushland produces. With heritage clear, this is the control most likely to change the build specification.

Named watercourses in St Ives Chase
2 named watercourses are mapped in St Ives Chase. 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.
- Cowan Creek
- Kuring-Gai 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.
