One40william–Australian Green Superstar



Major mixed-use project exceeds all green aspects of developers requirements

Designed by HASSELL, the one40william project in Perth, Australia has exceeded all aspects of developer Cbus Property’s project requirements and those of their major State Government tenant.

The development was required to obtain the certification for “5 Star” Green Star Design rating, Australia’s standard assessment for sustainability, and achieved a score of 72 points. There is also a requirement for the project to achieve a 5 Star As-Built rating.

The $350m one40william project will provide 36,000 sq m commercial office and 6,000 sq m retail, food and entertainment tenancies, it looks set to become Perth’s most influential new commercial development in decades. Influential, for the effect its contemporary architecture will have on the Perth skyline as well as the energy efficient and environmentally sustainable design that will set new benchmarks for tenant comfort and corporate social sustainability.

The stepped and angled floor plan and multilevel design places the highest tier on the north side to provide a natural shading system for the lower office levels. This, paired with the use of a single glazed façade, prevents excessive heat gain in summer while radiating warmth to its surrounds at night. 

Featuring rooftop and surrounding gardens that are irrigated using rainwater harvested on site, as well as a high proportion of fresh air circulation in the office spaces, the design has a focus on worker comfort.

Construction is currently unfolding with anticipated completion and occupation in early 2010.
