What we look for in Cottesloe, and why it differs from the suburb next door. 10.2 km from the CBD, on the coast, postcode 6011.
Cottesloe was named in 1886 and declared a suburban area straight away, with the first four-acre lots sold about two years later. A land rush in the mid 1890s put houses up quickly, and by 1898 a thousand people lived here. The railway had already run through since 1881.
Original stock is late 1890s and 1900s, Federation era, followed by interwar building. Solid brick without cavity or damp-proof course. Timber floors on stumps. A hundred and twenty years of alteration to trace.
The Town of Cottesloe holds 430 heritage-listed places, twenty seven of them on the State Register. In a suburb of three point nine square kilometres that is a lot of protection, and it means repairs and replacements are not always a free choice. Check the listing for the actual address before planning anything.
Directly on the Indian Ocean, this is maximum salt exposure for the metropolitan area. Delignification leads on any older tiled roof. Corrosion works steadily on fixings, flashings and external metalwork. Maintenance history predicts condition here better than build year does.
Roughly one dwelling in six is a flat or apartment, which is a meaningful strata component for a suburb this size, and coastal strata brings concrete condition to the front of the queue.
The Norfolk Island Pines are part of the place. Century old roots. A hundred and sixty eight saplings were bought by the Roads Board in 1915, with more planted after. Those are now century-old root systems in a suburb of century-old drainage.
Coastal sand keeps general pressure lower than inland. The exposures here are specific.
Timber floors on stumps put the subfloor first on the Federation stock, and access under a house of that age is often poor. Ventilation was limited when built and later additions usually made it worse.
The pines are the local factor. Mature root systems find drainage, and a displaced clay line beneath a century-old cottage produces a permanently damp patch of ground that nobody sees until something else goes wrong. On a suburb where both the trees and the drains date from the same era, that is worth checking rather than assuming.
Barriers on stock this old are absent. Not expired. Absent.
On a Federation house the subfloor and the roof answer both inspections, and where heritage limits what can be replaced, knowing the full condition matters more than usual. Reported under AS 4349.1 and AS 4349.3.
If a property has mature pines nearby, ask when the drains were last camera surveyed. Century-old roots and century-old clay lines are a predictable combination and the survey costs a fraction of the repair.
Heritage work brings staged inspections during approved repairs and reports where a dispute over what was permitted has started. We also do coastal strata inspections, where concrete condition and the scheme's spending record decide whether an apartment is a sound buy. A tidy lot in a building with deferred facade work is a bill you have not received yet.
Cottesloe sits on the Quindalup dune system — young calcareous sand, still mobile in places, and thin over the water table near the front. Sand this young has low bearing capacity but very little reactivity, so footing movement is uncommon and drainage problems are not. What the ground gives you here it takes back in the air.
What that means in practice, on a house in Cottesloe:
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.
Peppermint Grove, Claremont, Swanbourne, Mosman Park and Mount Claremont sit on the same ground as Cottesloe, 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.
Dalkeith is 3.4 km away but sits on the Spearwood 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 Cottesloe 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 →
Right on the coast in Cottesloe - Claremont, and salt does the damage this close to the water. The flat fee buys a hard look at the tile battens for delignification, at the wall ties and metal fixings for corrosion, and at the rust bleed through render that looks cosmetic and is not. The tiled-roof void is the priority.

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.
Cottesloe is on the coast, inside the band where delignification should be expected in tile battens. On a tiled roof more than about ten years old it is one of the first things we look at.
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:
