The cloud object consists of a supporting steel structure designed to shut down the pneumatically tensioned ETFE roofing sheet. The “cloud” structure is made up of twelve intersecting trusses. These trusses are made up of circular tubes and winding bars and are interconnected by circumferential rings, forming the foil's anchor profile. The upper truss also serves as a drainage trough. The roof structure is supported by six columns and horizontally secured by six tie rods and a pair of push struts.
