The curved form of this 160m commercial tower, designed by Rafael Vinoly Architects, tapers elegantly outward from a small footprint. Above the office floor is a spectacular public SkyGarden offering panoramic views to the north over the city of London and to south over the Thames. The enclosure for the SkyGarden series of doubly-curved steel portal frames which span the full distance of the floor plate and are a continuation of the building’s signature fin expression. Glass panels enclose the zones between the portals and a 15m tall curved glass walls at the north and south ends are suspended from the roof portals above.
