The museum's extension prominently protrudes from the adjacent older, lower buildings. Seemingly shoved into the previously empty site it literally overshadows the old part of the gallery which stems from the late 19th century. The cantilevered facade is ostensibly hovering above a large aperture revealing the inner courtyard of the adjacent reappropriated old water barracks. While the material looks like exposed concrete from afar, the building is actually cased in gray painted wood paneling.

In use.
