german practice archwerk has created the headquarters for ig metall located in bochum, germany. the structure’s form responds to the region’s industrial character with a cubic motif that is evident in the fenestration arrangements. a central space is created within the void left between the two separated volumes. a glass roof spans between them creating an enclosed atrium with abundant natural light and sustained vegetation. clinker masonry of varied hues defines the exterior appearance while a metal and glass curtain wall borders the interior spaces.

communal gathering and socializing occurs within view of the transparent entry hall while the office spaces are placed on higher levels overlooking the nearby urban center. the design offers an undefined floor plan which can be easily transformed for the working methods of various tenants. four steel stepped terraces bordering the neighboring westpark provide an outdoor experience while also mediating for the seven meter change in elevation.
