Designed by HASSELL, one40william is one of Perth's most significant and influential new buildings, enlivening the city's retail centre and setting a benchmark in environmental sustainability.
Based on progressive responses to workplace design, public realm, climate and context, the building has been designed from the inside out rather than fitting functions into a predetermined aesthetic.
The building design strives to engage people who work within, visit, and simply pass by it through careful consideration of urban grain, streetscape, heritage, activity, scale and texture. Integral to the success of the building are the permeable linkages created with the surrounding city and the underground railway station beneath the building itself.
The design celebrates Perth's specific microclimate by taking best advantage of light and shade in the overall building orientation and design and incorporating extensive landscaped rooftop spaces and winter gardens.
The project has achieved a 5 Star Green Star Office Design rating (and is targeting a 5 Star Green Star Office As Built rating) with a range of initiatives including: built form to maximise natural light, views and self shading, bicycle parking and end of trip facilities, reduced car parking, grey water storage and high-efficiency, low-temperature VAV air-conditioning.
