What we look for in Seville Grove, and why it differs from the suburb next door. 23.8 km from the CBD, 17.0 km from the coast, postcode 6112.
Seville Grove is one of the more practical family suburbs in the Armadale and Kelmscott corridor, developed mainly from the 1980s and 90s. It is newer than the old township cores nearby, and it continues to fill in with smaller cottage lot housing.
So there are two eras sitting side by side. Thirty years apart. Established homes from the 1980s and 90s, now thirty to forty years old and moving between their first and second maintenance cycles, with hot water systems, roof fixings and wet area waterproofing all arriving. And newer small cottage lot builds with a quite different list.
The cottage lots bring their own issues. Narrow blocks, tight access. Narrow blocks mean zero lot walls built hard against a boundary, close spacing between houses, and drainage that has to work in the gap between two buildings. Access for any future repair is restricted, which turns a straightforward job into an awkward one. Where a wall sits on the boundary, ownership and maintenance responsibility need to be understood rather than assumed.
The suburb sits on southeast corridor Pinjarra Plain reactive clay, so footing and slab movement are ordinary seasonal considerations, and there is some low and wet ground near the brooks. Inland. Salt is a low priority.
Narrow lots concentrate the risk in a way larger blocks do not. On a cottage lot the perimeter is often paved or landscaped right up to the wall, so the slab edge is buried along much of its length, and the gap between two houses can be too tight to inspect properly. We report where access defeated us.
Zero lot walls make it harder again, because one face of the building cannot be examined from your own property at all.
On the 1980s and 90s stock the original chemical barrier has reached the end of its effective life and most have not been renewed. Reactive clay cracking gives concealed access toward footings in summer. Newer builds should carry a durable notice recording their termite management system, so find it and check whether the landscaping since has bridged it.
On a tight lot the awkward part of any inspection is getting to the perimeter and the roof, so doing that once for both assessments rather than twice is a genuine saving. Reported under AS 4349.1 and AS 4349.3.
Cottage lot infill generates most of the other work. Condition records before a neighbouring build starts matter more here than on larger blocks, simply because the new house will be a metre or two from your wall.
We do staged inspections during construction and handover checks at completion. Disputes tend to concern boundary walls and drainage between closely spaced houses, or damage caused during adjacent building work. We prepare reports for owners dealing with them.
On a zero lot wall, establish before purchase who owns it and who maintains it. That answer is not always what buyers assume, and it is far cheaper to find out now.
Seville Grove sits on the Bassendean dune system — deep leached grey quartz sand, almost pure, and very free draining. Bassendean sand is about as unreactive as a building site gets, so seasonal footing movement is rarely the story here. The water table is the story. Parts of this system sit over the Gnangara Mound and the standing water level can be within a couple of metres of the surface.
What that means in practice, on a house in Seville Grove:
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.
Haynes, Armadale, Camillo and Mount Richon sit on the same ground as Seville Grove, 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.
Mount Nasura is 3.3 km away but sits on the Guildford Formation; Kelmscott is 3.8 km away but sits on the Guildford Formation. 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.

Well inland at 17.0 km from the coast, out in Gosnells, the inland setting changes what the fee buys in Seville Grove: footing and slab movement, drainage and the reactive soils of the South East belt come first, and coastal delignification is a lower priority away from the arterial corridors.

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 17.0 km inland, Seville Grove 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.
