Positioned above the Perth Underground station, at the corner of William Street and Murray Street Mall, 140 William® comprises three office towers above one level of retail, dining and entertainment.

With an GFA of 41,000sqm, the building is designed to be sensitive and responsive to its heritage surrounds with the refurbishment of the Wellington Street buildings along with the restoration of the Mitchell façade on William Street.

The 5.5 Star NABERS Energy rated office tower has been orientated and massed so that it is self-shading.  Unique enclosed and semi enclosed garden spaces are scattered throughout the floors to provide outdoor amenity to the various tenants.
