The building type of the depart­ment store has a long tradition. As early as the late 19th century, technical innovations made it possible to replace the closed facade with large glass surfaces, thus opening it up to the outside.

A transformation of this curtain wall and the opening of the build­ing play a special role in this project: the stern quadratic grid of the facade is dissolved by tilting the eight large windows in differ­ent angles and directions. The reflections of the surrounding historic city center are mirrored in the large windows.

‘For passers-by, looking into the store windows becomes a view of the heavens.’
