The Hales

The Hales estate in Forrestfield is a 400-lot residential community transformed from land formerly owned by Western Power and released to market through a competitive tender by the Western Australian State Government.

Cossill & Webley partnered with Satterley Property Group from the outset, providing engineering expertise during the due diligence and acquisition process that contributed to their successful bid for the site.

Following purchase, we played a pivotal role in the structure planning phase and led the detailed civil design and superintendence of works. The site presented significant challenges – being surrounded by established development, crossed by major 330kV overhead powerlines, and existing sewer infrastructure. A key achievement was negotiating with authorities to enable recreational and drainage uses within the powerline easements, maximising usable land and delivering strong planning outcomes.

Environmental and community enhancements were also central to the project. The design retained key areas of native vegetation and incorporated the restoration of the Crumpet Creek waterway, boosting ecological value and local amenity. The Hales stands as an example of how innovative engineering and thoughtful planning can unlock complex infill sites to create vibrant, high-quality residential communities.
