Diversity conceived as a spatial principle: the “schmale Hans” combines color and material. The blue-green glazed clinker bricks from GIMA give the building a clear, contemporary architectural attitude. In Mannheim’s Spinelli Wohnen.Park.Quartier, a new urban development on the site of the former Spinelli Barracks, the Viennese architecture firm AllesWirdGut has designed an ensemble of distinctive individual houses that not only allows for diversity, but also makes it visible.
