Why this is harder than it looks in Turramurra
- A current licence tells you nothing about solvency
External administrators lodged 2,361 initial reports for construction companies in 2024–25 — more than any other industry in the country (ASIC Insolvency Statistics, Series 3.1). Every one of those companies held a valid licence the day before. The certificate on the wall says they are permitted to build. It does not say they can pay their framer on Friday.
- Turramurra is not a generic block
Mapped here: 3 residential zones, 2 overlay families, 316 heritage records. 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 Turramurra regularly already know which of these reach which streets.
- "Get three quotes" sells you, not the builder
The standard model charges builders per enquiry and sends the same one to several of them. You are the product, the fastest caller wins, and nobody in that chain has checked whether any of them is solvent. We do not sell enquiry data — not to a panel, not to a lead broker, not ever.
The mechanism
Four checks, before anyone reaches you
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 Turramurra
Confirmed with the builder against the suburbs they genuinely service — not a radius drawn on a map.
What you are dealing with in Turramurra
Six things a builder prices differently. This is the suburb-level picture — which of them reaches your block is an address check.
- Bushfire Not mapped BAL assessment; glazing, decking and screening spec.
- Flood Not mapped Sets a minimum floor level. Flood report first.
- Heritage 316 records Impact statement; limits demolition, form and materials.
- Slope Not mapped Geotech report before footings can be priced.
- 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 (240 of 322 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 (275 of 418). On an 800 m² block that is about 240 m² of floor area, every level counted.
- Land reserved for acquisition
Parts of Turramurra are reserved for future public acquisition — infrastructure, public recreation. A reservation is mapped to specific land, so whether it touches your block has to be checked at the address.

Overlay families mapped in each suburb we have read in this region. More mapped controls generally means more assessment before you can price a build.
Builders serving Turramurra
What building in Turramurra actually involves
Turramurra carries 316 mapped heritage records — the second heaviest load in Ku-ring-gai after Wahroonga — across a suburb that also holds all three residential zones. That combination, rather than either fact alone, is what makes it a difficult suburb to price without reading the address first.
Items and conservation areas are different problems
An individual heritage item constrains that property. A heritage conservation area constrains everything inside it: your own house need not be listed, because new work is assessed against the area's character — its setbacks, its roof forms, its materials, sometimes its fence line. Turramurra has both, and the second kind is the one that surprises people, because nothing about the house itself signals it.
A 9.5m ceiling over most of it, and 17.5m over the rest
Height is mapped on 322 parcels here. The most common control is 9.5 metres, covering 240 of them, and the upper band runs to 17.5 metres. Nine and a half metres is a comfortable two storeys and an attic; it is not three. The higher mapping sits around the station and the highway rather than through the residential streets, so a block a few hundred metres apart can permit a materially different building.
Floor space ratio does the rest of the work
A floor space ratio of 0.3:1 applies to most mapped parcels. On a 1,000 m² block that is 300 m² of gross floor area before any concession — generous for a house, restrictive for the kind of dual-occupancy some owners assume the medium-density zoning permits. Read the FSR and the height together; either one alone will mislead you.
Lot sizes are large, and that changes the quote
The most common minimum lot size band is 900–999 m², one of two mapped in the suburb. Large blocks mean longer service runs, longer driveways, more site works and more landscaping — real line items that a quote priced off frontage will not carry.
Trees and soil
Ku-ring-gai is heavily treed and tree controls routinely shape footprints here rather than merely inconveniencing them; Sheldon Forest and The Glade sit inside the suburb. Acid sulfate soils are mapped in Turramurra as well, which matters the moment a design involves a basement, a pool or any excavation of depth.
What this means for a knockdown rebuild
Establish three things before you commission a design: whether a heritage item or conservation area reaches the block, which height band and FSR are mapped at the address, and what the arborist says about anything you were planning to remove. A builder who has worked through Ku-ring-gai's assessment before will ask for all three unprompted.
The lot-size split, in parcels
Two minimum-lot-size bands are mapped across Turramurra, and the split is lopsided: 272 parcels at 900–999 m² and 78 at 1,000–1,999 m². Roughly one block in four therefore sits in the larger band, and the 1,000 m²-plus parcels are where subdivision and dual-occupancy questions become worth asking. They are also where the site-works budget quietly grows, because a longer block means a longer driveway, a longer service run and more retaining on any fall.
Two kinds of heritage mapping, and only two
The heritage records intersecting Turramurra fall into two categories in the state's data: general items and general conservation areas. That is a simpler picture than several neighbouring Sydney suburbs, which also carry landscape and archaeological listings, and it narrows the check you need to run. Either a specific property is listed, or a boundary has been drawn around a group of streets. There is no third thing to discover late.
The height figure is a majority, not a rule
Height is mapped on 322 parcels and 9.5 metres covers 240 of them. The other 82 parcels are not at 9.5 metres, and that is the number worth holding onto. A one-in-four chance that the suburb-wide figure is wrong for your block is not a rounding error — it is the difference between a design that works and one that has to be redrawn. The same applies to floor space ratio: 0.3:1 is mapped on 275 parcels of the 418 that carry a ratio at all.
What a Turramurra knockdown rebuild usually runs into
In order of how often it derails a program: a conservation area boundary nobody checked, a tree that turns out to be non-negotiable, and a height or FSR figure taken from the suburb rather than the parcel. None of the three is expensive to check and all three are expensive to discover after a design is paid for. Ku-ring-gai's assessment is thorough rather than fast, so build the time for it into the program at the start.

Questions about building in Turramurra
What is the difference between a heritage item and a conservation area?
An item constrains that specific property. A conservation area constrains everything within its boundary, including houses that are not themselves listed, because new work is assessed against the area's character. Turramurra has 301 mapped items plus conservation areas.
Which planning instrument applies?
The Ku-ring-gai Local Environmental Plan 2015, administered by Ku-ring-gai Council. It sets the zoning, the heritage mapping and the development standards.
Can I build units on a Turramurra block?
Only where medium or high density zoning applies, which is mainly around the station and the highway. Most of the suburb is low density. Check your address before assuming.
Will tree controls affect my design?
Very likely. Ku-ring-gai's tree protections are strict and established trees frequently decide where a house can sit. Arborist first, designer second.
Why are acid sulfate soils mapped this far inland?
They matter for anything that disturbs soil at depth — basements, pools, deep footings. Acid sulfate soils are mapped in Turramurra; whether they reach your block needs checking against the address.
How this works
- 01Tell us about the build
Six questions, about three minutes.
- 02We match it against Turramurra
Against the 3 residential zones mapped here, 2 overlay families, 316 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.
No catch
What you are agreeing to
- Nothing. There is no contract with us, no account to create, no card, and nothing to cancel.
- No obligation to use whoever we recommend. Take the name and the reasoning and do what you like with it, including nothing.
- No phone number needed to start. Give us one if you want to be called; otherwise we write.
