The office building houses the regulatory authority of the city of Cologne. In the two glazed staircases we hid the linear luminaries in such a way that you cannot detect any light source from outside. This supports very much the vertical walls which constitute the space and which are covered with abstract-geometrical artwork by Achim Zeman.
The lighting concept of the spacious office floors takes into account the glass partition walls and uses downlight with a very low glaring rate to prevent irritating reflections.
