The design concept is briefly explained by three images: the “Glass Box” containing the main conference center, the “Cloud” the main auditorium space contained and the “Blade”, a free-standing separate object- the Hotel. The Cloud encloses: an auditorium for 1850 people, snack points and support services to the auditorium. The Cloud structure in steel ribs is covered by 15,000m2 of translucent material.
