The exposed corner side is located on a busy traffic hub in Düsseldorf. Due to the development plan, the location, orientation and maximum extension of the building were specified. The task was to design a building that isn’t losing its effect in the cityscape, both when viewed from a distance and when viewed closely. A meandering ground plan with a depth of 13.50 meters is mirrored several times over its longitudinal axis and generates atriums that extend alternately over several floors. The vertical element façade, in contrast to the fully glazed atria, coherently implements the urban planning concept and gives the building its identity and presence in the city.
