Webb Yates Engineers designed the feature steelwork package for this office building, including various atria, façade engineering and the design of an innovative stressed skin profiled metal deck roof.
The brief for the atrium roofs was to achieve something visually arresting and different in an otherwise fairly cool and reserved building. The structure needed to span 18m and be stiff enough to support glazed infill. Webb Yates designed roof beams in standard metal sheeting to form units in a 3D hypar form. The sheeting forms a shear diaphragm, unifying corner angle sections such that they become a stiff Toblerone box like truss.
