Home builders in Moana
Construction leads every industry in Australia for insolvencies. Before you hand anyone a deposit in Moana, we check their licence with Consumer and Business Services, 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 Moana
- 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.
- Moana is not a generic block
Mapped here: 4 residential zones, 6 overlay families, 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 Moana 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 Consumer and Business Services's own public register — number, class and status, with the date we looked recorded.
- 02 · Insurance
Public liability plus whatever warranty or indemnity cover SA 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 Moana
Confirmed with the builder against the suburbs they genuinely service — not a radius drawn on a map.
What you are dealing with in Moana
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 Mapped Sets a minimum floor level. Flood report first.
- Heritage None mapped Impact statement; limits demolition, form and materials.

How Moana compares in Southern Adelaide
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 Moana
What building in Moana actually involves
Moana maps a maximum building height of 24.5 m and, in levels, up to six levels — inside a coastal suburb of just 2.4 km² that also maps a one-level maximum elsewhere in the same boundary. That spread, from one level to six, is the defining planning fact here, and it is what a buyer needs to understand before assuming a beachside outlook is permanent.
One level to six, in two and a half square kilometres
The Code maps maximum building height in two forms and both vary: 10.5 m and 24.5 m in metres, and 1, 2, 3 and 6 levels in levels. A design can satisfy one form and fail the other, so both have to be read. More importantly for a homeowner, the control on the land next to you is a separate question from the control on yours. A 24.5 m envelope beside a single-level house is the sort of thing that is obvious from the mapping and invisible from the street.
No heritage mapping at all
Moana records no heritage places, and neither a Local Heritage Place nor a State Heritage Place overlay is mapped in the suburb. Aldinga Beach carries both overlays and four recorded places; Seaford carries the State overlay. For Moana that means the heritage question simply does not arise: a knockdown rebuild faces no listing check and no character assessment. The only comparable control here is the Regulated and Significant Tree overlay, which can still determine where a house sits and what may be excavated near a root zone.
Site area: 250 m², 270 m², or four hectares
Three minimum site area rules are mapped: a detached dwelling minimum of 250 m² in some parts, 270 m² in others, and a 4 hectare minimum on the rural-zoned land. Alongside that, two frontage rules — 8 m and 9 m detached dwelling minimums. The compact minimums make a small-lot or row-dwelling proposition genuinely available on parts of Moana; the rural minimum makes it impossible on others.
Four zones, including Rural Living
General Neighbourhood, Housing Diversity Neighbourhood, Master Planned Neighbourhood and Rural Living are mapped. The presence of Rural Living in a 2.4 km² coastal suburb is what produces the four-hectare rule, and it means a Moana address can be a compact beachside lot or acreage. Those share no cost structure: on rural living land, driveway, service runs, water supply and potentially on-site wastewater are the build.
Bushfire and flood together
High Risk, General Risk and Urban Interface bushfire categories are mapped, along with Hazards (Flooding — High) and Hazards (Flooding — General). Carrying a High Risk bushfire band and a High flood band in one small coastal suburb is unusual, and they apply to different parts of it — the bushfire mapping follows vegetation and the interface with it, the flood mapping follows the low ground and the watercourses. A block can be in one, both or neither, and where the High flood mapping applies it can set a minimum finished floor level.
No acid sulfate soils
The mapping we hold records none in Moana, where Aldinga Beach records one. That removes an earthworks step, so what happens below ground is a geotechnical question, not a contamination one. On coastal sand the geotechnical question is the substantive one anyway: bearing, and the depth to a competent layer, decide whether a conventional slab works or piers are needed.
Sand, not just salt
On dune-front land there are two mechanisms at work and they are frequently conflated. Salt drives corrosion, which is a materials-grade question. Wind-driven sand drives abrasion, which is a finish and detailing question — it strips coatings, scours glazing, and finds its way into tracks, seals and mechanical hardware. A specification chosen for corrosion alone can still be the wrong specification for abrasion. Sliding door tracks, window seals and any external motorised hardware are where the difference shows up first.
What to establish first in Moana
The height control at your address and on the land beside it, because one level and six levels are both mapped here. Then the zone and the minimum site area — 250 m² and four hectares are both live. Then bushfire and flood, which reach different parts of the suburb. Then the site classification on sand and the exposure category.

Questions about building in Moana
How tall can a building be in Moana?
It varies sharply. Maximum heights of 10.5 m and 24.5 m are mapped in metres, and 1, 2, 3 and 6 levels in levels, across 2.4 km². Read both forms at your address — and on the land beside you, because that decides your outlook.
Is Moana heritage-constrained?
No heritage places are recorded and neither the Local nor State Heritage Place overlay is mapped in the suburb. A knockdown rebuild here faces no listing check and no character assessment — only the Regulated and Significant Tree overlay applies.
What minimum site area applies in Moana?
Three rules are mapped: a detached dwelling minimum of 250 m² in some parts, 270 m² in others, and a 4 hectare minimum on rural-zoned land. Two frontage rules also apply — 8 m and 9 m detached dwelling minimums.
Does Moana have both bushfire and flood risk?
Yes, in different parts. High Risk, General Risk and Urban Interface bushfire categories are mapped, along with High and General flood categories. A block can be in one, both or neither, and High flood mapping can set a minimum finished floor level.
What foundation should I expect on coastal sand?
It depends on the site classification for the lot. On sand, bearing and the depth to a competent layer decide whether a conventional slab works or piers are needed — a substantial cost difference that a soil test settles before contract.
How this works
- 01Tell us about the build
Six questions, about three minutes.
- 02We match it against Moana
Against the 4 residential zones mapped here, 6 overlay families, bushfire-prone land — and against which builders hold the right licence class for it, have done it before, and actually work under City of Onkaparinga.
- 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 Moana, we say so. That is a real answer we give, and the empty builder list above is the proof we mean it.
