Three shell support structures will in the future provide access to the new underground station concourse. The domed structures made from extruded aluminium sections are put together with 3D milled nodes. Each node is unique and realised as a gridshell node with a screw channel. The trigonal glass elements, with an edge length of 700mm, are made of 3-ply laminated safety glass. High quality stainless steel portal frames and integrated door systems complete the resulting façade surfaces under the domes, to ensure they are draught and weatherproof.
