Perth Hills, WA · Acreage subdivision

Stoneville

Stoneville is a 20-hectare landholding in the Perth Hills, secured for its scale in a market where genuine acreage close to Perth is almost never created anymore. Subdivision approval is granted for 10 lots of 1 to 3 hectares, offering the increasingly rare combination of hills lifestyle and real proximity to the city. Titles are expected in 2027.

Coolbellup, WA · Battle-axe subdivision and new build

Coolbellup

Coolbellup is the 21M playbook at its simplest: find the underused land behind an existing home and put it to work. One lot became two in a battle-axe configuration, with the original dwelling retained at the front and a new 3 bedroom, 2 bathroom home built on the rear lot. Completed in 2025, it added a brand new dwelling to an established suburb without demolishing anything, the kind of quiet infill available on an ordinary suburban block.

Olive Grove

Olive Grove took a raw Healesville site from paddock to titled residential land in a Yarra Valley township with structurally limited land supply. Once planning approval established the lot yield, a six-month civil programme delivered the new serviced lots in 2021.

Ambrose Street

Hills sites reward developers who respect the terrain, and Ambrose Street in Emerald was bought on that basis. The six-month civil programme was built around water management, delivering titled lots in 2023 in a township where buildable, properly drained land is scarce, on a street that reads as established rather than new.
