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.
Boya is a small Shire of Mundaring suburb on the lower eastern face of the Darling Scarp, between Greenmount and Midland, at the point where the scarp descends most steeply toward the Swan Valley floor. It is known for the granite quarrying that operated here from the 1890s through to the mid-twentieth century — the pink Boya granite was used in the construction of the Perth GPO and other major early twentieth-century buildings — and the quarrying history has left the suburb with a specific ground character: exposed granite outcrops, former quarry sites and the irregular surface topography of a locality where rock has been actively worked. A building and timber pest inspection in Boya reads for that quarried granite ground alongside the steep scarp drainage and the bushland that borders the suburb on the uphill sides.
The quarried granite ground is the most specific Boya read in this coverage area. Homes built on or near former quarry sites sit on ground that has been disturbed at depth — cut, blasted, and left with the subsurface irregularity of actively worked stone. The compaction profile beneath residential footings on former quarry ground differs from natural rock outcrop, and the drainage channels cut by quarrying operations may still direct subsurface water in ways that the natural topography would not. We read the footing behaviour and the site drainage on Boya lots with the quarrying history as the specific ground context.
The steep scarp descent is the second read. Boya is on the face of the scarp at its steepest point toward the valley, and the gradient on some Boya lots is among the most pronounced of any residential suburb in the inner eastern metro area. Retaining structures managing that gradient, site drainage managing the scarp rainfall on steep lots, and the building perimeter management at the base of the slope are all primary structural reads on gradient-affected Boya properties.
The surrounding bushland on the uphill scarp side provides the native vegetation context for the pest read. Native jarrah and marri maintained in the bush above the suburb give termites the food source and moisture access that the scarp provides throughout the extended hills winter.
The housing stock is predominantly 1970s and 1980s residential on the established streets, with the occasional older rural-residential home on larger lots. Each earns the read of its own construction era on the quarried and scarped ground of Boya.
What you get is a plain reading of the Boya home on its quarried granite scarp ground and at its specific 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 Greenmount and Koongamia.

Homes on or near former quarry sites sit on ground disturbed at depth — cut, blasted, and left with the subsurface irregularity of actively worked stone. The compaction profile beneath footings on former quarry ground differs from natural rock outcrop, and old quarrying drainage channels may still direct subsurface water unexpectedly.
Pink Boya granite, used in major early twentieth-century Perth buildings including the GPO. Quarrying operated from the 1890s through to the mid-twentieth century, leaving the specific disturbed-ground and topographic character that makes Boya distinct.
Boya is on the steepest part of the scarp face toward the Swan Valley. Gradient on some lots is among the most pronounced of any residential suburb in the inner eastern metro. Retaining structures, slope drainage management and building perimeter management at the base of the slope are primary structural reads on steep lots.
Retaining walls at ages from 40 to 50 years managing pronounced scarp-face gradients are primary structural reads — their condition, drainage relief and the load they are managing at this age are pre-purchase and inspection concerns of the first order.
Yes. Native jarrah and marri in the uphill scarp bush above the suburb provide food source and moisture access sustained through the extended hills winter.
Old quarrying drainage channels may direct subsurface water in ways the natural topography would not, affecting the drainage behaviour of the building site in ways not apparent from the surface.
Primarily 1970s and 1980s residential on established streets, with the occasional older rural-residential home on larger lots. Each earns its construction-era read on the quarried and scarped Boya ground.
Yes. Building to AS 4349.1 and timber pest to AS 4349.3, one visit, one report within 24 hours.
A flat $616 inc GST for both scopes, report within 24 hours.
The retaining structure condition first, then the footing behaviour on the disturbed quarry ground, then the drainage management of the former quarry channels and the steep scarp gradient in heavy rain.
