1 William Street

Sculptural Tower a Unified Landmark for Queensland.

A major catalyst project for the wider waterfront precinct, the new commercial office tower at 1 William Street has been designed to accommodate the Queensland Public Service while providing a symbol of its strong sense of purpose, identity and confidence in the future.

Positioned on the banks of the winding Brisbane River, the form of the tower invites an abstraction of the continuous, sinuous line of the river articulated via the glazed tower design. A lustrous façade, the tower’s cladding reflects and changes with the time of day and quality of sunlight, apparently adjusting to seasonal and climatic variations. The crown of the tower is defined by a sharp chamfer facing outward towards the state of Queensland, providing a distinctive skyline statement that is instantly recognisable from a distance. Creating a striking visual profile, the splayed rooftop terrace allows guests to experience the sub-tropical climate of Brisbane and enjoy unparalleled panoramic views of the city.

Conceived from the inside-out, a full-height atrium enables a non-hierarchical, inclusive work space. Connectivity on and between floors was a key driver to fulfilling the brief, with a variety of workspaces delivering a mix of individual and team-based activities.

Drawing inspiration from the Queensland landscape, the finishes scheme seeks to emulate the natural environment, bringing the outside in via the application of colour, materiality and texture. Building on a neutral base palette of cream, lightly stained timber and grey tones, each level of the building moving up the tower takes cues from the state’s icons as well as native flora and fauna. A compelling new workplace for the Government of Queensland, 1 William Street provides a distinctive new icon for the city of Brisbane positioned within an invigorated public realm and mixed use lifestyle precinct that connects the Brisbane CBD to the river.



Aiming for connectivity

The aim is to create interconnectedness, to create connections where no connections currently exist; between the Botanic Gardens and the Brisbane River, the Brisbane River and the City, the City and the workplace and within the workplace itself. At ground level, the building is lifted so that the building appears to float over a dynamic network of pedestrian and view corridors that will connect the site to its surroundings.

The unique collaborative central core allows extraordinary daylight and views in 360 degrees. With the sky garden on one side and the laneway connections through the core, our team has created a new type of central core, which provides:

  • Collaborative space
  • Circulation flows that respond to workplace ‘desire lines’ and functionality
  • Concentrated spaces for quiet working
1 William Street’s forecourt and ground level will be a welcoming place that physically and visually connects the development to surrounding streets, precincts, gardens and the Brisbane River.


A message of symbolism

The form of the tower is angled away from the Brisbane CBD so it sits sensitively within the immediate CBD context but also looks outward to the interior of Queensland sending a strong message of inclusion and an ethic of an open and engaged public service.

What these spaces share is that they are well used by the public and embody a distinctive Queensland style.

1 William Street is the missing link in Brisbane’s cultural pedestrian loop. The site is presently a very low amenity pedestrian, cyclist and ferry commuter gateway into the Garden Point education and government precinct.

The Cbus Property proposal for 1 William Street will support the renewal of this area by creating a new civic destination and surrounding public spaces with their own unique offer to the people of Queensland.

"The dedication and devotion of our employees led to the completion of the largest commercial tower in Brisbane,” said Chief Executive Officer Nik Karalis. “The collective intelligence of our Global Studio included collaboration and engagement from Adelaide, Brisbane, London, Melbourne, New York, Sydney and Perth, working together on the base build and integrated fitout.”

The ideal workplace

The innovative central core floorplate allows for the core to be a porous, usable environment, creating a complete floor solution instead of the traditional central core solution.

Large floor plates allow flexible and efficient office layouts. Floor areas range from 1,607 m2 to 2,086 m2, with minimal columns and core intrusions.

Internal access between floors can easily be delivered to meet tenant needs. The building design gives the impression that floors are interconnected. A unique ‘collaborative central core’ brings daylight and 360 degree views into the building, and there is the potential for 3 level sky garden atriums on one side of the space.

Overall, the design promotes a collaborative space that is a modern and effective platform for creating the ideal workplace.
