Far more than just a means of getting to different floors, four individually unique boulevard stairs are wide and deep, creating a place where people can circulate and connect, enhancing their overall experience.
With their distinct curved geometry, the stairs from levels 00 to 04 interconnect with all the elements of the structural frame – the existing structure, the floor plates, cores and perimeter structure. They typically span as distinct U-shaped elements, with the vertical sides forming the balustrades. The soffits are formed as continuous planes, with void formers minimising weight, whilst achieving the architectural shape. Between levels 05 and 10, the stairs wrap around and cantilever from a central spine wall supported off the core below.
The design of the stairs and supports, along with their construction sequence, were carefully considered to accommodate the complicated interfaces, the geometrical challenges and the exposed concrete. In combination with the building’s layout, their positioning enables visitors to view each floor with ease.
