The newly converted top floor of the east wing of the Bundeshaus had to be made accessible by a lift. The delicate structural environment needed to be taken into account. Only a few centimetres remained for the shaft pit and the shaft head. Together with Co. Architekten, formerly alb Architektengemeinschaft, a maximally transparent and statically self-supporting solution was developed. The result impresses the user with its unobtrusiveness.
