Architects Designstudio Regina Dahmen-Ingenhoven, Düsseldorf Material Alphamesh 12.0 Stainless Steel Ringmesh 12.0 Stainless Steel Quantity approx. 2 500 m² The alphamesh curtain is composed of more than 26 million individual welded rings and encloses the premises like a work of art. With a height of 10m, the curtain meanders along a total length of 250m. Apparently cloaking yet open like a transparent door at the same time. What lies behind the curtain can only be guessed at and never unveiled. As soon as it becomes dark, the curtain changes into a 2,500m² stage on which continuously changing coloured lights are displayed.
