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

Why this is harder than it looks in Kogarah
- Kogarah is not a generic block
Mapped here: 3 residential zones, 2 overlay families, 63 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 Kogarah 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 Kogarah actually involves
Kogarah's numbers refuse to summarise. The most common maximum height is 39 m — on 20 of 74 mapped parcels. The most common floor space ratio is 4.5:1 — on 16 of 69. Neither is a majority, and a figure that holds on a quarter of the land is not a fact about a suburb.
A plurality of a minority is not an answer
Planning summaries habitually report the most common value and leave it there, and on most suburbs that is fair because one control genuinely covers most of the land. Here it does not. Twenty parcels out of seventy-four is the single largest group, which means roughly three-quarters of mapped parcels carry something other than 39 m — and the page cannot tell you what, because there is no second number with any claim to represent the place either. The same is true of the floor space ratio. So the honest instruction on a Kogarah parcel is not to adjust for a suburb figure but to discard the idea of one: get the height and the floor space ratio for the address, because block-by-block is the actual pattern rather than an inconvenience.
Two lot bands that are not neighbours
Two minimum-lot-size bands are mapped: 1000–1999 m² on 24 parcels and 450–474 m² on 12. Those are not adjacent steps — one is roughly double the other at its lower bound and more than four times at its upper. A parcel in the smaller band and a parcel in the larger are different products with different buyers, and the suburb name does not distinguish them.
Three residential zones, and a 39-metre entitlement somewhere
R2 Low Density, R3 Medium Density and R4 High Density Residential are all mapped under the Georges River Local Environmental Plan 2021, with R2 recorded as dominant. Hold that against the height figures: the land carrying a 39 m control is not R2 land, so the dominant zone and the most common height describe different parts of the same 2.6 km².
Sixty-three heritage records and a conservation area
Sixty-three heritage records are mapped, including a general conservation area. A conservation area reaches land with no listing of its own, so on a suburb of this size it is worth establishing the boundary rather than assuming an unlisted parcel sits outside it.
Acid sulfate soils, and two clear registers
Five acid sulfate soil features are mapped; the trigger is excavation depth rather than what is built above. No bush fire prone land is mapped in Kogarah, and the suburb is in no declared mine subsidence district — both read results from statewide registers rather than unchecked assumptions.
What to establish on a Kogarah block
The height control and the floor space ratio for the address, because no suburb-level figure is defensible here. Then which lot band applies, since the two are far apart. Then the zone. Then whether the conservation area reaches the parcel.
What you are dealing with in Kogarah
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 checked Held in each council's own Flood Planning Map rather than in a statewide layer
- Heritage 63 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 · 39m What may be built, and how much. Set parcel by parcel.

Worth knowing before you budget
- Building height
No single height control covers much of Kogarah: the most common is 39m, on 20 of 74 mapped parcels. Height here is set block by block. No other height control covers a meaningful share of the suburb.
- Floor space ratio
Floor space ratio varies across Kogarah: the most common mapped value is 4.5:1, on 16 of 69 parcels. It has to be read 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 Kogarah
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 Kogarah
Against the 3 residential zones mapped here, 2 overlay families, 63 heritage records — and against which builders hold the right licence class for it, have done it before, and actually work under Georges River 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 Kogarah — 3 residential zones, 2 overlay families, 63 heritage records — and against which builders hold the right licence class, have built under these constraints before, and genuinely work under Georges River 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 Kogarah 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 Kogarah 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 Kogarah, 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 Kogarah 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 Kogarah
What is the height limit in Kogarah?
The most common maximum height is 39 m, but it applies to only 20 of 74 mapped parcels — so roughly three-quarters of mapped land carries something else. There is no defensible suburb-level figure.
Why can't you give me one number?
Because a figure that holds on a quarter of the land is not a fact about a suburb. The same is true of the floor space ratio, whose most common value of 4.5:1 applies to 16 of 69 parcels. Block-by-block is the actual pattern here, not an inconvenience.
What are the lot sizes?
Two bands: 1000–1999 m² on 24 parcels and 450–474 m² on 12. Those are not adjacent steps — a parcel in each is a different product with a different buyer.
What zone is Kogarah?
R2 Low Density, R3 Medium Density and R4 High Density Residential under the Georges River Local Environmental Plan 2021, with R2 dominant. The land carrying a 39 m control is not the R2 land.
Is Kogarah heritage-affected?
63 records are mapped, including a general conservation area — which reaches land with no listing of its own, so establish the boundary rather than assuming an unlisted parcel sits outside it.
Is Kogarah bushfire-prone or in a subsidence district?
Neither. No bush fire prone land is mapped and it is in no declared mine subsidence district — both read results from statewide registers. Five acid sulfate features are mapped, triggered by excavation depth.
What to ask a builder about a block in Kogarah
Each one is here because of something mapped in Kogarah. Take them to whoever quotes.
- 01
Which of the 3 residential zones mapped in Kogarah covers this address, and what does that one permit that the others do not?
- 02
Have you had an application through Georges River Council where a heritage control applied, and how long did the assessment take?
- 03
What height control is mapped at this address? It is set block by block in Kogarah, not suburb-wide.
- 04
What floor space ratio applies at the address, and what floor area does that actually allow on this block?

Named watercourses in Kogarah
Muddy Creek is the one named watercourse mapped in Kogarah. Where a block sits relative to it is a design input rather than a view: it sets the riparian setback and, in a heavy event, the overland flow path.
- Muddy 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.
