Home builders in Marino
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 Marino job can still pay its framer on Friday. We run the Four-Point Builder Check™: licence with Consumer and Business Services, insurance sighted, still trading, and genuinely working in Marino. Then one name and the reasoning behind it — or a straight no.
- Costs you nothing, ever
- No obligation to use them
- Details never sold
Why this is harder than it looks in Marino
- Marino is not a generic block
Mapped here: 4 residential zones, 5 overlay families, 4 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 Marino 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 Marino actually involves
Marino covers 3.46 km² and carries four different neighbourhood zones — Hills, Waterfront, General and Master Planned. They are not scattered. The suburb runs from high ground down to the coast, and the zoning changes with the landform.
The zone follows the topography, so the address decides it
Hills Neighbourhood is recorded as dominant, and a hills zone carries expectations about siting on slope, cut and fill, retaining, driveway gradient and how a building reads from below. Waterfront Neighbourhood is a different proposition again, addressed to land relating to the coast. Because the boundary between them tracks the fall of the land rather than a street grid, two properties on the same road can sit in different zones — and the design that suits one is not the design assessed under the other. Establish the zone by parcel before engaging a designer, because on sloping ground the zone shapes the section, not just the floor plan.
A master planned zone in the mix
Master Planned Neighbourhood is also mapped. On that land the governing document is the plan for the release rather than the general provisions, so the research path is different from the rest of the suburb: read the plan, and read its staging.
Three water instruments, answering different questions
Flooding hazard is mapped at both High and General, and Coastal Flooding is mapped separately. The first two describe water arriving overland; coastal flooding describes the sea reaching a height. On a suburb that falls toward the coast the three do not overlap neatly — high ground can be clear of all of them while a parcel a hundred metres downhill sits in two. Ask which apply, by name, and get the level for each.
No bushfire overlay, and no acid sulfate
No Hazards (Bushfire) overlay is mapped across Marino, and no acid sulfate soils are mapped. Both are read results from the Code rather than gaps, which means no Bushfire Attack Level applies and no acid sulfate investigation is triggered by excavation depth.
Heritage, and a tree overlay
Four heritage records are mapped as Local Heritage Place. A Regulated and Significant Tree overlay also applies, triggered by trunk circumference rather than species — which on established sloping blocks with mature plantings reaches more properties than expected, and matters most where a tree sits where the cut would go.
What to establish on a Marino block
The zone, by parcel — Hills against Waterfront against Master Planned — because on this landform the zone governs how the house meets the ground. Then which of the three water instruments apply and at what level. Then whether a regulated tree stands where you intend to build.
What you are dealing with in Marino
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 Mapped Sets a minimum floor level. Flood report first.
- Heritage 4 records Impact statement; limits demolition, form and materials.
- Slope Not checked No statewide landslip layer in the Planning and Design Code
- Soil None mapped Below trigger depth: management plan, treatment, disposal.
- Density controls 4 zones What may be built, and how much. Set parcel by parcel.

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 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 Marino
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 Marino
Against the 4 residential zones mapped here, 5 overlay families — and against which builders hold the right licence class for it, have done it before, and actually work under City of Marion.
- 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 Marino — 4 residential zones, 5 overlay families, 4 heritage records — and against which builders hold the right licence class, have built under these constraints before, and genuinely work under City of Marion. 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 Marino 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 Marino 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 Marino, 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 Marino is that quotes are only comparable when they assume the same things — and with 4 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 Marino
What zone is Marino?
Four neighbourhood zones are mapped — Hills as dominant, plus Waterfront, General and Master Planned. They are not scattered: the suburb falls from high ground to the coast and the zoning changes with the landform.
Why does the zone matter more than usual here?
Because a Hills zone carries expectations about siting on slope, cut and fill, retaining, driveway gradient and how a building reads from below. On sloping ground the zone shapes the section, not just the floor plan — so establish it by parcel before engaging a designer.
Can two houses on the same street be in different zones?
Yes. The boundary tracks the fall of the land rather than a street grid, so two properties on one road can sit in different zones, and the design that suits one is not the design assessed under the other.
Is Marino flood-affected?
Three instruments are mapped: flooding hazard at High and at General, and Coastal Flooding separately. The first two describe water arriving overland, coastal flooding describes the sea reaching a height. High ground can be clear of all three while a parcel downhill sits in two.
Is Marino bushfire-prone?
No Hazards (Bushfire) overlay is mapped across Marino, and no acid sulfate soils are mapped. Both are read results from the Code rather than gaps, so no Bushfire Attack Level applies and excavation depth does not trigger an acid sulfate investigation.
Do I need approval to remove a tree in Marino?
A Regulated and Significant Tree overlay applies, triggered by trunk circumference rather than species. On established sloping blocks with mature plantings it reaches more properties than expected, and matters most where a tree stands where the cut would go.
