From the winding ‘Botanical Walk’ adjacent to Alice Street, to the even gradient of the pathway next to Gardens Point Road/Margaret Street, the design of the landscape of the site offers many ways to get from river to city.
Place
The tower acknowledges the topography and landscape of its place like none other. The overall design concept of the tower recognised that the site is located on the edge of the riparian zone between the city grid and the river bank of the Brisbane River…the tower is an object in a ‘natural’ landscape. Through this fundamental difference in tower design from the CBD (tower and podium), this building encourages the landscape to dominate the experience of the ground plane and create multiple connections from city to river where none existed previously.
The site layout offers many different opportunities to traverse the site and slope of the land between the city and river.

Tower Design
1 William Street provides a workplace culture and a flexible working environment that engender more efficient and effective service delivery to the people of Queensland.
Some of the floor plate design include:
- rounded corners to mitigate hierarchies and space ‘ownership (much like a round table);
- 10, 3 storey atriums, facing the city and Parliament House, with flowing interconnecting stairs that connects more people on more floors, visible to the city and the citizens;
- centralised social, collaboration and meeting spaces around the atriums encouraging more interaction;
- stepped, open, terraces at the crown of the building, allowing guests the ability to experience the Queensland climate.
The tower form is defined by a sharp chamfer facing out toward the state providing a distinctive skyline statement that is instantly recognisable from a distance.
Tower Expression

The design of the tower invites an abstraction of the continuous, sinuous ‘line’ of the river up the tower, around the crown and down to the ground again, articulating the tower façade, defining the atrium spaces with clear, louvre free glass so that maximum transparency from the city can be offered.
