Construction of the 1 William Street office tower is underway.

Project phase



The 1 William Street (1WS) office tower will be a landmark structure.

When completed in late 2016, this landmark office tower will provide a modern and efficient workplace for more than 4,000 Queensland Government employees, as well as private sector tenants.

1WS is also the catalyst for a planned revitalisation of the Queens Wharf Brisbane precinct. The revitalised precinct may include a mix of six star hotels, retail centres, restaurant and entertainment zones, theatre and convention facilities, and new open spaces.

Cbus Property is developing the 1WS office tower which is now 50 per cent owned by ISPT (Industry Superannuation Property Trust). The main construction contractor for the development is Brookfield Multiplex, with the office interior being designed by Woods Bagot.

Information on the 1WS design is freely available on the Brisbane City Council development application website.

Objectives of the development

The Queensland Government's objectives for developing 1WS are to:

  • enhance Brisbane's reputation as a vibrant city with modern, landmark architecture in a well-planned urban environment
  • accommodate the Queensland Public Service and create a highly productive environment for team members focused on achieving the best outcomes for the businesses and people of Queensland
  • reinvigorate and act as a catalyst for change in the Queens Wharf Brisbane precinct
  • achieve value for money for the State
  • create a high quality, sustainable development on the site
  • activate this project in the shortest possible time as part of the Government's priority to boost the State's economy.
