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

Why this is harder than it looks in Unley
- Unley is not a generic block
Mapped here: 6 residential zones, 6 overlay families, 71 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 Unley 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 Unley actually involves
Unley maps six residential and mixed zones across 1.5 km², and with them minimum site areas running from 150 m² to 750 m². A five-fold spread in how much land a dwelling needs, inside one suburb name, is the fact that governs everything else here.
Minimum site area is the subdivision gate
For anyone considering dividing a block or putting more than one dwelling on it, minimum site area is the number that decides whether the idea is possible at all. Seven separate rules are mapped in Unley. At the 750 m² end, a typical allotment supports one house and nothing more. At the 150 m² end, the same land could carry several dwellings. Between those two answers lies most of the value difference between otherwise similar properties — and the answer is not visible from the street, not inferable from what a neighbour did, and not constant across the suburb.
Read the rule for the dwelling type you actually want
South Australian minimum site areas are frequently written per dwelling type in the same rule — a detached dwelling, a semi-detached, a row dwelling, a group dwelling and a residential flat building can each carry a different figure. A block that cannot be divided for two detached houses may comfortably take two semi-detached or row dwellings. So the question is not "can this block be subdivided" but "what dwelling type does the applicable rule permit on this land, and at what area". Those are different questions with different answers.
Frontage is the second gate, and it is independent
Six minimum frontage rules apply, from 10 m to 18 m. Frontage and site area are assessed separately, so a resulting allotment must satisfy both — a deep, narrow block can meet the area requirement comfortably and fail on frontage. Where subdivision is the plan, run both calculations before anything else.
Height runs to 32.5 m and nine levels
Twelve height figures in metres are mapped alongside six in levels, from 10.5 m and one level up to 32.5 m and nine levels. As elsewhere in South Australia both caps apply and the more restrictive governs. The tall figures belong to the Urban Corridor (Boulevard) and Urban Renewal Neighbourhood zones rather than the residential streets — but on a 1.5 km² suburb those are never far away, so the height mapped on adjoining land is worth knowing if outlook matters.
Housing Diversity and Urban Renewal zones
Both are mapped, and the names describe intent: these are zones where the Code anticipates more and different housing than the established pattern. For an owner that cuts two ways — more scope on your own land if you are in one, and more change around you if you are beside one.
Setbacks and coverage
Primary street setbacks of 0 m and 6 m are both mapped — a wide difference. The side boundary setback is 1 m for the first level and 3 m above, with maximum site coverage of 50 per cent.
Heritage and trees
State Heritage Place, Local Heritage Place and Historic Area overlays are all mapped, along with a Regulated and Significant Tree overlay. The area overlay reaches unlisted houses, which is the case most often missed. Flooding is mapped in both the High and General bands somewhere in the suburb; whether either reaches a specific allotment is an address check.
What to establish first in Unley
The minimum site area and frontage for the address, and for the dwelling type you actually want. Then the zone, since six are mapped. Then the height figures on your land and the land beside it. Then the heritage overlays and the trees.
What you are dealing with in Unley
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 71 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 6 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 Unley
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
Seven questions, about three minutes.
- 02We match it against Unley
Against the 6 residential zones mapped here, 6 overlay families, 71 heritage records — and against which builders hold the right licence class for it, have done it before, and actually work under City of Unley.
- 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 Unley — 6 residential zones, 6 overlay families, 71 heritage records — and against which builders hold the right licence class, have built under these constraints before, and genuinely work under City of Unley. 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 Unley 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 Unley 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 Unley, 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 Unley is that quotes are only comparable when they assume the same things — and with 6 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 Unley
How much land does a dwelling need in Unley?
Anywhere from 150 m² to 750 m² — seven separate minimum site area rules are mapped across six zones in 1.5 km². At one end an allotment supports a single house; at the other the same land could carry several dwellings.
Can my block be subdivided?
That is the wrong question here. Minimum site areas are usually written per dwelling type in the same rule, so a block that cannot take two detached houses may comfortably take two semi-detached or row dwellings. Ask what dwelling type the applicable rule permits, and at what area.
Does frontage matter separately?
Yes, and it is assessed independently. Six frontage rules apply, from 10 m to 18 m, and a resulting allotment must satisfy both frontage and area — so a deep narrow block can meet the area comfortably and fail on frontage. Run both calculations first.
How tall can buildings be?
Twelve height figures in metres and six in levels are mapped, from 10.5 m and one level up to 32.5 m and nine levels. Both caps apply and the more restrictive governs. The tall figures belong to the corridor and renewal zones rather than residential streets.
What do the Housing Diversity and Urban Renewal zones mean?
That the Code anticipates more and different housing there than the established pattern. It cuts two ways — more scope on your own land if you are in one, and more change around you if you are beside one.
