One40William is a mixed-use commercial development located in the heart of Perth’s central business district, directly above Perth’s underground railway station. The development, designed by Hassell, links commercial, retail, hospitality and civic spaces in a style that is modern and dynamic, yet also incorporates the three existing heritage structures that form part of the development’s façade. Also featuring multi-level basement carparking, landscaped rooftop gardens, wintergardens, and extensive natural light penetration into the commercial office tenancies, One40William is the largest building in Western Australia to gain a 5 Star Green Star Office Design rating.
