What we look for in Herne Hill, and why it differs from the suburb next door. 20.1 km from the CBD, 24.4 km from the coast, postcode 6056.
After the First World War, Herne Hill and its neighbours were carved into soldier settlement blocks. Small holdings were allocated to returned servicemen to farm. By the 1920s the Swan Valley was a vineyard district dominated by table grapes and dried fruit, and the Swan Settlers Co-operative built its large packing shed here in 1923.
Soldier settlement housing was modest by design. Men were placed on small holdings with limited capital. They built accordingly. Where original dwellings survive, expect simple construction and minimal footings, plus a century of incremental extension by successive owners.
The agricultural structures matter as much as the houses. This was table grape and dried fruit country before it was a wine district, which means drying sheds and packing structures, along with substantial rural outbuildings. Many are old, many are unmaintained. Some were never approved. They need assessing in their own right or explicitly excluding, and on a rural holding they are frequently worth more to the owner than the house.
The ground has been cultivated for a century, so old irrigation and bores apply on some parcels, along with a long history of agricultural chemical use. The Swan Valley Protection Act 1995 constrains subdivision and land use here, so check what is actually permitted before making plans that depend on it.
Vineyard country has a specific termite exposure that suburban blocks do not, and it comes from the infrastructure rather than the house.
Trellis posts run in long lines across a property, set directly into soil and often left in place long after vines have gone. Irrigation keeps that soil damp through summer. Old sheds sit on the ground rather than on footings. Stacked timber accumulates. So does disused equipment, and the odd abandoned structure, on holdings farmed for a hundred years.
The dwelling itself may be timber floored, in which case the subfloor is the priority and access is often poor in an old cottage. Any chemical barrier is long gone. Agree in advance which structures on the property are covered, because on a holding like this the scope needs settling before anyone arrives.
On a rural holding the practical case is time. Walking the dwelling and the outbuildings takes most of a morning once the water supply and the effluent system are added. Doing structure and timber pests in one attendance is the only sensible arrangement, and it puts one person across the whole property rather than two people across parts of it. Reported under AS 4349.1 and AS 4349.3.
Rural properties generate expert witness work over boundaries, access and unapproved structures. We also do dilapidation reports. Pre-settlement inspections matter on a holding where equipment and materials can be moved or removed between offer and settlement.
Where new building is permitted, building stage inspections cover site works and drainage while they are visible, and practical completion inspections follow. Being well inland, salt and delignification play no part here.
One thing worth asking on any valley holding. Find out whether the property is inside the protected valley area or outside it, because that single line on a map governs what you may do with the land.
Herne Hill sits on the Guildford Formation — alluvial clay and sandy clay laid down by the Swan and Canning systems. This is the reactive ground. Clay here shrinks and swells with moisture, which is what puts stepped cracking through brickwork and takes doors out of square between seasons. Articulation joints matter on these sites, and a great many older houses do not have them where a current standard would want them.
What that means in practice, on a house in Herne Hill:
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.
Minh Quang Meditation Institute is the fixed point most people in Herne Hill navigate by. Buildings like it are useful to an inspector for a duller reason: they date the area. Whatever era put that up is usually the era that put up the houses around it, and the construction methods of that decade are what we expect to find in the roof.
West Swan, Brabham, Middle Swan, Henley Brook and Belhus sit on the same ground as Herne Hill, 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.
Stratton is 4.8 km away but sits on the laterite foothills of the Darling Scarp. 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 24.4 km from the coast, out in Kalamunda, the inland setting changes what the fee buys in Herne Hill: 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 24.4 km inland, Herne Hill 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.
