Project phase



The 1 William Street (1WS) office tower will be a landmark structure in the heart of Brisbane's government precinct.

When completed in late 2016, this landmark office tower will provide accommodation for an estimated 4,000 Queensland Government employees, as well as private sector tenants.

1WS is also the catalyst for a planned revitalisation of Brisbane's lower George Street precinct. The revitalised precinct may include a blend of office and commercial spaces, hotels, cultural facilities, residential developments and retail centres.

Cbus Property is developing the 1WS office tower. Cbus Property's main construction contractor for the development is Brookfield Multiplex. The workplace designer is Woods Bagot.

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 Government Administrative 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.
