Home builders in Kiama
Construction leads every industry in Australia for insolvencies. Before you hand anyone a deposit in Kiama, we check their licence with NSW Fair Trading, sight their insurance, confirm they are still trading — and match you to the one who actually builds on blocks like yours.

Why this is harder than it looks in Kiama
- 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.
- Kiama is not a generic block
Mapped here: 3 residential zones, 3 overlay families, 120 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 Kiama 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 Kiama
Confirmed with the builder against the suburbs they genuinely service — not a radius drawn on a map.
What you are dealing with in Kiama
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 120 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 · 8.5m · 0.45:1 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 8.5m (116 of 158 mapped parcels). Other controls that apply to a meaningful number of parcels run up to 14.3m — generally centres and larger sites, not a house block.
- Floor space ratio
A floor space ratio of 0.45:1 applies to most of the mapped parcels here (99 of 183). On an 800 m² block that is about 360 m² of floor area, every level counted.

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 Kiama
What building in Kiama actually involves
Kiama maps a dominant floor space ratio of 0.45:1 — on 99 of 183 mapped parcels — alongside a dominant maximum building height of 8.5 m. Together those two numbers describe a low, spacious pattern of building, and they are among the most restrictive dominant controls we have published anywhere.
0.45:1 is the number to do arithmetic with
Floor space ratio caps total floor area as a multiple of site area, counting every level. At 0.45:1, an 800 m² block permits about 360 m² of floor area across the whole house. That is a generous family home and it is nowhere near what the block's size might suggest to someone reasoning from land area alone. Because the control is dominant here — covering more than half the mapped parcels — it is a reasonable planning assumption rather than something to discover, but the arithmetic should still be done against your actual land area before a designer is briefed.
Height reinforces it, and the upper figure is not far away
The most common height control is 8.5 m, on 116 of 158 mapped parcels — strongly dominant, and generally two storeys. The upper control mapped is 14.3 m. Read the two together and the picture is consistent: a two-storey house occupying under half its land. That is a deliberate outcome rather than an accident of mapping, and it is what gives these streets their character.
120 heritage features in under ten square kilometres
A high density of listings for a town of 9.79 km². Where one reaches a property, consent covers demolition and new work alike, tested against the significance recorded for it. Conservation areas are the instrument that reaches unlisted properties, assessing new work against the character of the area — worth searching separately from the item list.
Two lot bands, and they are not close
The most common minimum lot size is 450–474 m² on 13 parcels, with 300–349 m² on five. Between those two the subdivision answer differs materially, and the band is not inferable from the street.
Acid sulfate soils on the coastal flats
Four acid sulfate features are mapped. Digging to or past that class level brings a consent requirement and a plan for the material — which reaches excavation method, spoil handling and dewatering rather than the house design. On most Kiama blocks this will be a light finding, but it matters directly if a pool or below-ground work is in the brief.
Three zones, and a coastal specification
R2 Low Density, R3 Medium Density and R5 Large Lot are mapped. Separately, and in no planning layer: a site near this coast sits in a genuine marine environment, and the exposure category assessed for the specific site — not the town — governs the external material specification. Worth naming in a quote rather than assuming.
What to establish first in Kiama
The floor space ratio multiplied by your actual land area, because that is the size of the house. Then the height control, which is strongly dominant at 8.5 m. Then heritage, item and conservation area separately, given 120 features. Then the lot band, the acid sulfate position and the exposure category.
What to ask a builder about a block in Kiama
Each one is here because of something mapped in Kiama. Take them to whoever quotes.
- 01
Which of the 3 residential zones mapped in Kiama covers this address, and what does that one permit that the others do not?
- 02
Have you had an application through Kiama 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 Kiama, not suburb-wide.
- 04
What floor space ratio applies at the address, and what floor area does that actually allow on this block?

Questions about building in Kiama
How much house can I build in Kiama?
A floor space ratio of 0.45:1 applies to most mapped parcels — 99 of 183. On an 800 m² block that is about 360 m² of floor area across every level. Do the arithmetic against your actual land area before briefing a designer.
How tall can I build?
The most common control is 8.5 m, on 116 of 158 mapped parcels — strongly dominant, and generally two storeys. The upper control mapped is 14.3 m. Read with the floor space ratio, the picture is a two-storey house on under half its land.
Is heritage likely to apply?
120 features are mapped in under ten square kilometres, which is a high density of listings. Conservation areas reach unlisted properties and assess new work against the character of the area — search those separately from the item list.
Can I subdivide here?
It depends which band applies. The most common minimum is 450–474 m² on 13 parcels, with 300–349 m² on five. The answer differs materially between them and cannot be inferred from the street.
Do acid sulfate soils affect me?
Four features are mapped. Reaching the class level in excavation triggers both consent and a management plan — which reaches excavation method, spoil handling and dewatering. It matters most if a pool or below-ground work is planned.
How this works
- 01Tell us about the build
Six questions, about three minutes.
- 02We match it against Kiama
Against the 3 residential zones mapped here, 3 overlay families, 120 heritage records — and against which builders hold the right licence class for it, have done it before, and actually work under Kiama 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.
- One builder contacts you, not six. And only after you have seen the brief and said yes.
- Your details go to that builder and nobody else. Never sold, never auctioned, never shared with a panel.
- If we have nobody in Kiama, we say so. That is a real answer we give, and the empty builder list above is the proof we mean it.
