What we look for in Parkwood, and why it differs from the suburb next door. 11.6 km from the CBD, 14.4 km from the coast, postcode 6147.
Parkwood was part of Lynwood until 1993 and stayed semi rural until the 1960s. Large parcels were then developed by a British firm, Realty Development Corporation, and marketed to new English migrants as a garden suburb. The estate stock reflects that origin.
House and land package homes of the 1960s and 70s were built to consistent specifications, which makes the suburb predictable. The same era problems recur across streets, so knowing the standard build tells us where to look before arriving.
At fifty to sixty years old, expect services original or into an ageing first replacement. Asbestos era materials in anything unrenovated. Roof fabric, roof plumbing and wet area waterproofing all arriving at once. None of that is unusual for the age, and all of it should be priced rather than discovered.
Two local features shape particular blocks. Whaleback Golf Course, opened in 1981, sits on a buffer reserve between the Canning Vale industrial area and the housing here. So some homes face fairway margins and others face the industrial buffer, and those are different propositions. Fairway frontage brings irrigation, a raised water table along the boundary and the occasional golf ball. The Canning catchment also means reactive clay and low ground on some blocks, with footing movement to match. Being inland, salt is a low priority.
The golf course is the distinguishing factor and it works in a specific way. Fairways are irrigated heavily and continuously through summer on a scale no domestic garden approaches, and that keeps ground along the boundary damp when the rest of the suburb has dried out.
Moisture is the limiting factor for subterranean colonies, so a fairway margin block carries higher pressure than an interior street. The buffer reserve vegetation between here and the industrial area holds colonies too.
Across the suburb the age related drivers apply. Fifty year old gardens with buried timber. Original barriers long finished. On slab built stock the perimeter and slab edge are the focus, particularly where decades of paving and garden beds have covered the junction. On reactive clay sections, seasonal cracking gives concealed routes toward footings that would otherwise be exposed.
On a consistent single storey house both inspections cover the same perimeter, drainage and roof space, so one attendance is the obvious approach. On a fairway block it also means one person assesses what the irrigation is doing to the ground rather than two forming separate impressions. Reported under AS 4349.1 and AS 4349.3.
Mature estate stock on reasonable blocks brings renovation and subdivision, so building stage inspections and practical completion inspections come up on new builds. Dilapidation reports apply where that work adjoins an established house.
We also do pre-settlement inspections and expert witness reports. If you are buying on the course boundary, walk the rear of the block after a week of irrigation and see how the ground feels underfoot. Damp there in February tells you what to expect all year.
Parkwood 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 Parkwood:
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.
Willetton, Lynwood, Ferndale, Riverton, Wilson and Shelley sit on the same ground as Parkwood, 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.
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 14.4 km from the coast, out in Gosnells, the inland setting changes what the fee buys in Parkwood: 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 14.4 km inland, Parkwood 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:
