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

Why this is harder than it looks in St Ives
- St Ives is not a generic block
Mapped here: 3 residential zones, 2 overlay families, 136 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 St Ives 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 actually involves
St Ives is the most uniform suburb in this part of Ku-ring-gai, and that is its defining planning characteristic. Height is mapped on 296 parcels and the 9.5-metre control covers 262 of them — around nine in ten, where in neighbouring Gordon the equivalent figure is closer to half. What varies here is not the envelope. It is everything underneath it.
Why uniformity is useful to know
In a suburb where the height control is near-universal, a builder quoting a two-storey house is unlikely to be caught out by the envelope. That moves the risk somewhere else: trees, soil, heritage and the slope of the individual block. It also means that where a parcel does fall outside the common band, it is genuinely exceptional and worth confirming rather than assuming.
Heritage, at a third of Wahroonga's load
St Ives maps 136 heritage records — light by Ku-ring-gai standards, substantial by most others. The item-versus-conservation-area distinction still governs: an item constrains the listed property, an area constrains everything within it and is assessed on character rather than on the age of your own house.
No railway station, and what that changes
St Ives sits off the North Shore line. The practical consequence for a build is that the high-density mapping which clusters around stations elsewhere in Ku-ring-gai has less to cluster around here, which is part of why the height mapping is as uniform as it is. The upper band tops out at 17.5 metres rather than the 29 metres mapped in Gordon and Pymble.
Floor space, lot size and the large-block economics
A floor space ratio of 0.3:1 applies to most mapped parcels, and the most common minimum lot size band is 900–999 m². On a block of that size, 0.3:1 is roughly 300 m² of gross floor area — comfortable for a substantial house, tighter than people expect for a dual occupancy.
Trees are the real constraint
Dalrymple Hay Nature Reserve, Huntleys Forest, Bead Forest and Browns Forest all sit in or against the suburb, and the remnant canopy through the residential streets is why tree controls here decide where a house can go rather than simply requiring paperwork. Get the arborist involved before the footprint is fixed, not after.
Soil and excavation
Acid sulfate soils are mapped in St Ives. It is a depth question: shallow work is unaffected, and anything involving a basement, a pool or significant cut needs the trigger depth established early because it changes both earthworks and disposal.
What to ask first
Confirm the block is inside the common 9.5-metre band, get the tree position surveyed before the design is set, and check whether a conservation area reaches it. In St Ives, in that order.
What you are dealing with in St Ives
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 136 records 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 3 zones · 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 (262 of 296 mapped parcels). Other controls that apply to a meaningful number of parcels run up to 17.5m — generally centres and larger sites, not a house block.
- Floor space ratio
A floor space ratio of 0.3:1 applies to most of the mapped parcels here (265 of 382). On an 800 m² block that is about 240 m² of floor area, every level counted.
- Land reserved for acquisition
Parts of St Ives are reserved for future public acquisition — classified road, infrastructure, public recreation. A reservation is mapped to specific land, so whether it touches your block has to be checked at the address.
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
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
Against the 3 residential zones mapped here, 2 overlay families, bushfire-prone land, 136 heritage records — 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 — 3 residential zones, 2 overlay families, 136 heritage records — 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 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 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, 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 is that quotes are only comparable when they assume the same things — and with 3 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 St Ives
Is St Ives easier to build in than Turramurra or Pymble?
On heritage, generally yes — 129 mapped items against roughly 300 in each. But blocks near the national park pick up bushfire and vegetation considerations those suburbs carry less of. The constraint moves rather than disappears.
Does backing onto the national park affect my build?
It can significantly. Proximity to bushland brings vegetation controls and bushfire construction requirements, including asset protection zones. Get the bushfire assessment early — it is a design input, not a compliance step at the end.
What zoning applies in St Ives?
Low, medium and high density residential zones are all mapped, with higher density concentrated around the shopping village and Mona Vale Road. Which applies to your block is address-specific.
Can I subdivide?
It depends on the minimum lot size mapped for your address — most commonly 900 to 999 square metres in St Ives. Check the specific address rather than the suburb pattern.
Is St Ives bushfire prone?
If your block is at or near the bush interface, almost certainly. It determines the construction standard, and the standard changes the build price. Do not leave it to the end.
What to ask a builder about a block in St Ives
Each one is here because of something mapped in St Ives. Take them to whoever quotes.
- 01
Which of the 3 residential zones mapped in St Ives covers this address, and what does that one permit that the others do not?
- 02
What bushfire attack level have you built to in St Ives before, and what did it change in the glazing, decking and screening?
- 03
Have you had an application through Ku-ring-gai Council where a heritage control applied, and how long did the assessment take?
- 04
What height control is mapped at this address? It is set block by block in St Ives, not suburb-wide.

Named watercourses in St Ives
6 named watercourses are mapped across St Ives. At that density the buildable ground is largely what sits between them, and the gullies they run in set the fall — which decides earthworks long before the floor plan does.
- Cowan Creek
- High Ridge Gully
- Kuring-Gai Creek
- Lovers Jump Creek
- Middle Harbour Creek
- Stony 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.
