Independent inspection to AS 4349.1 by a registered building contractor. What you are buying, read by someone who has built. Report within 24 hours.
Hilbert is where the outer Armadale estate meets the Darling Scarp face — a suburb built between 2005 and 2020 on ground that transitions from the reactive clay-loam of the Armadale plain to the granite-and-laterite foothills of the scarp, with the Darling Range Regional Park closing off the eastern boundary. A pre-purchase building inspection here navigates that transition: two different ground types beneath the estate, construction-era defects from the building boom, and a park boundary that gives the highest Hilbert lots termite access conditions that the lower plain lots do not share. The inspection is building scope only, to AS 4349.1.
\n\nThe two-ground-type estate is the most site-specific aspect of the Hilbert pre-purchase. We use the building's own slab and crack-pattern behaviour to identify which type dominates beneath the specific lot — clay-loam seasonal movement on the lower blocks, or the granite-face rapid-drainage signature on the upper blocks — and the pre-purchase report records which type applies and what its implications are for the home's future behaviour.
\n\nConstruction defects at 5 to 20 years are the building priority across all Hilbert lots. The eastern park-boundary lots carry the highest combined termite context from the Regional Park native jarrah and marri alongside the scarp-foot moisture. The combined inspection is recommended for those lots. The report follows within 24 hours.
We run the same inspection across the area, including nearby Haynes and Mount Richon.

A building inspection to AS 4349.1 where the scarp-foot ground type — clay-loam lower or granite-laterite upper — is the first pre-purchase determination, followed by the construction-era defect profile and the Regional Park boundary context.
No, building scope only. The combined inspection is recommended for eastern park-adjacent lots.
Clay-loam lower lots carry seasonal reactive movement alongside construction defects. Upper scarp-foot lots carry shallow-granite drainage and the Regional Park termite boundary. We identify the dominant ground from the slab behaviour.
Marginal waterproofing, hollow render bonding and insufficient drainage falls from the 2005-to-2020 boom — all visible at 5 to 20 years and within the negotiation window.
Native jarrah and marri at the lot boundary on eastern streets — the food source and colony access that give those lots the highest termite conditions in the suburb.
Yes. Ground type identification and construction defect findings give you a factual pre-purchase basis.
Yes, particularly for eastern park-adjacent lots. The combined inspection is recommended there.
Yes. Slab behaviour and drainage management on both clay-loam and scarp-foot granite are primary pre-purchase reads.
Within 24 hours of the inspection.
Yes. Documented construction defects at purchase support warranty pursuit.
Also available as a combined building and timber pest inspection in Hilbert — both scopes in one visit to AS 4349.1 and AS 4349.3, one report within 24 hours.
