What we look for in Martin, and why it differs from the suburb next door. 23.6 km from the CBD, 25.0 km from the coast, postcode 6110.
Martin is a rural and semi-rural locality in the foothills of the Darling Scarp, east of Gosnells and Kenwick. It adjoins state forest and reserve land on the scarp side and is served by roads rather than public transport. The property here is the inspection, not the house.
Rural holdings mean septic or aerobic treatment systems, bore or tank water, long private driveways, and sheds and outbuildings that form part of the purchase. None of that is covered by an inspection of the dwelling, and on a rural block the sheds frequently carry real value.
Settle in writing which structures are included before anyone attends. It is the commonest source of disagreement on an acreage job and it takes one sentence to avoid.
The ground is the interesting part. At the foot of the scarp, soil shifts over short distances between coastal plain material and foothill gravel and laterite. A single holding can span both, which means footing behaviour varies across one property rather than being consistent through it.
So where a house sits within that transition matters, and it should shape how any cracking is read.
Tributaries of the Canning system cross the district, so low ground near a watercourse carries a seasonal water table. Bushland and state forest on the scarp side bring genuine bushfire exposure, and access on a long rural driveway is a practical question rather than a technical one.
State forest on the boundary is permanent habitat, and on a rural holding the dwelling sits within that landscape rather than at its edge. Pressure here is high and it does not vary with the seasons.
The transition ground works for pests as well as footings. Foothill gravel and laterite drain and are relatively unfavourable. Coastal plain material lower down holds water for longer, and where a holding spans both the pressure is uneven across one property.
Add the effluent system, which keeps a patch of ground damp near the house year round, and on sloping foothill land that moisture travels rather than staying put.
Firewood against a wall is close to universal up here and remains a bad idea.
On the dwelling, older rural houses on timber floors put the subfloor first and access varies with the slope. Barriers on anything of age are generally absent. Not expired. Absent.
Covering a rural holding takes hours once the outbuildings and services are included. The travel is real. One attendance, both standards. Reported under AS 4349.1 and AS 4349.3.
Buyers want the bore, the treatment system and the outbuildings assessed as specific items, since none is covered by assumption and all are expensive to put right.
Where building is happening, staged inspections cover site works and drainage while they remain visible. On transition ground, what the footings bear on is worth establishing early. Sand and laterite behave differently, a single property can have both, and the difference explains movement that would otherwise look like poor workmanship.
Martin sits on the laterite foothills of the Darling Scarp — lateritic gravel and clay over granite, with rock close to the surface and real slope. Slope is the defining feature. Cut and fill, split levels, and retaining walls are normal here rather than exceptional, and retaining is where the money goes wrong. Rock near the surface also means surface water runs rather than soaks.
What that means in practice, on a house in Martin:
Landform is assigned from the suburb's position on the Swan Coastal Plain rather than from a site soil test. It tells you what to expect, not what you have. A site classification to AS 2870 is a different exercise and a different report.
Roleystone and Carmel sit on the same ground as Martin, so the footing behaviour and the drainage problems tend to repeat across all of them. If you are comparing houses across those suburbs, you are largely comparing the same site conditions.
Kelmscott is 5.6 km away but sits on the Guildford Formation; Orange Grove is 6.5 km away but sits on the Guildford Formation; Gosnells is 6.8 km away but sits on the Bassendean dune system; Camillo is 6.9 km away but sits on the Bassendean dune system. That is the useful thing about this part of Perth: the ground can change inside a few kilometres, and with it what an inspection is looking for.
On site classification: any soil zone quoted for a suburb is indicative, inferred from geography rather than surveyed. A real AS 2870 classification comes from geotechnical work on your actual block and can differ from the one next door. We report what we observe; we do not read your soil class off a map.
The inspection is visual and non-invasive, over the readily accessible areas, reported to AS 4349.1. Our inspectors physically enter the roof space, as long as there is sufficient access. Report within 24 hours of the inspection.

Flat fee, the same in Martin as anywhere: $440 inc. GST for a pre-purchase building inspection, or $616 inc. GST with the timber pest scope added in the same visit. Full price list →
Well inland at 25.0 km from the coast, out in Gosnells, coastal salt is not the first thing an inspection in Martin chases. The fee buys closer work on footing movement, site drainage and the reactive-ground behaviour of the South East suburbs, with delignification checked only where a tiled roof meets a busy corridor.

Yes. Our inspectors physically enter and inspect the roof space, as long as there is sufficient access to do so safely. Where access is restricted, the report says so plainly rather than implying we saw more than we did.
At 25.0 km inland, Martin carries lower coastal-salt exposure, so delignification is not the first thing we would expect. It remains possible near heavy arterial corridors or industrial emissions.
Within 24 hours of the inspection itself, not 24 hours from booking. On a pre-purchase or pre-settlement job that timing is the whole point, because your leverage disappears once you are committed.
We would rather you checked than took our word for it. These are the bodies that actually hold the records and set the rules:
