Both scopes in one visit — building to AS 4349.1, timber pest to AS 4349.3. The fuller check, by a registered building contractor. Report within 24 hours.
Leda carries a ground condition found nowhere else in this coverage area: local groundwater, at around sixteen metres depth, is naturally high in salt. That saline groundwater is not the result of irrigation or contamination — it is the natural groundwater chemistry of this part of the Kwinana coastal plain, and it affects what can be planted, what requires treatment, and over time, the behaviour of the ground above it. A building and timber pest inspection at Leda reads for what naturally saline groundwater in the substrate means for the homes built above it, alongside the 1950s and 1960s State Housing Commission stock that was built here for the workers of the Kwinana industrial complex.
The saline groundwater is the specific Leda ground read. Groundwater naturally high in salt at sixteen metres is not at the level of the footings, but salt-laden groundwater that rises seasonally toward the surface in wetter years can affect the capillary moisture behaviour of the soil above it. Where subfloor conditions show moisture patterns that do not match the season or the surface drainage, the saline groundwater context is part of the explanation we carry into the read. We also note it as a site consideration for any planned excavation or earthworks on those blocks.
The 1950s and 1960s SHC housing is the building age read. Built to house the BP oil refinery, BHP steel and other Kwinana industrial workers, the homes of this era are now sixty to seventy years old and carry the standard age read for that period: the tile roof and its mortar at that age, the original wet area in long continuous use, and the services where these have never been renewed. The construction quality of the SHC period was sound but the materials are now carrying their age.
The Leda Nature Reserve, recognised in 1994 for its plant and animal diversity and home to permaculture gardens since 1992, sits around the heritage-listed Sloan’s Cottage from 1911. Homes adjacent to the reserve carry the permanent bushland-moisture boundary that any sizeable native reserve creates for neighbouring blocks.
The timber pest side follows the ground and the age. Saline-groundwater coastal plain soil, older SHC subfloors and the established vegetation of the nature reserve all give termites the conditions they use. We read subfloor, roof void and the perimeter carefully.
What you get is a plain reading of the Leda home on its specific ground and in its SHC era, with the report inside 24 hours and the real defects separated clearly from the cosmetic.
We run the same two-scope visit across the area, including nearby Calista and Kwinana Town Centre.

Its naturally saline groundwater. Local groundwater at around 16 metres depth is naturally high in salt — a natural characteristic of this part of the Kwinana coastal plain that is unique in this coverage area.
Salt-laden groundwater that rises seasonally toward the surface in wetter years can affect the capillary moisture behaviour of the soil above it. We carry that context into the subfloor and moisture read.
At 16 metres it is below the footing level, but in wetter years capillary rise can bring saline groundwater closer to the surface. We note it as a site consideration for any planned excavation or earthworks.
At sixty to seventy years: the tile roof and mortar, the original wet area in long continuous use, and the services where never renewed — the expected findings for Kwinana industrial-era housing.
Recognised in 1994 for plant and animal diversity, with permaculture gardens since 1992, around the heritage-listed Sloan's Cottage (1911). Reserve-adjacent homes carry the permanent bushland-moisture boundary context.
The 1911 heritage-listed cottage around which the Leda Nature Reserve is centred. Properties adjacent to the heritage site earn a note on that context.
Saline coastal plain soil, older SHC subfloors and the native vegetation of the nature reserve all give termites the conditions they use. We read the subfloor, roof void and perimeter carefully.
Yes. The building inspection to AS 4349.1 and the timber pest inspection to AS 4349.3 are done in one visit, with a single report within 24 hours.

After the brig Leda (1830), with the name also alluding to the Greek myth of Leda and the Swan — a double meaning noted at naming.
