About International Towers Sydney Tower 1

Constructed on a former container port, International Towers Sydney Tower 1 was part of the three building International Towers complex and part of the larger redevelopment of Barangaroo South into a new waterfront extension of Sydney’s Central Business District. International Towers was conceived as three sibling buildings with varying heights and specific design features to provide each building with its own identity. One of the identity markers is the in the arrangement and color of the vertical solar shades applied to the exterior facades, improving the thermal performance of the buildings as they were comprehensively designed with the context of their surroundings. The elevator cores were positioned to the northern edge of each building footprint, providing for expansive office floor plates while also further reducing energy consumption through a reduction of glazing on each building’s northern exposure.

Designing workspaces around social interaction was a key part of the design process, providing communal meeting areas beside the elevator cores interlinking workers throughout each building, while the entirety of the roofs, both at the podium and uppermost levels, are also available as open air terraces, courtesy of utilizing a centralized mechanical plant to efficiently provide services to all three buildings. At street level, all three buildings share a common basement and single entry point for vehicles in order to enhance the pedestrian friendliness of where the towers meet the ground.
