One reason for the trend towards natural terracotta with natural colours and textures is certainly the predicate of sustainability that manifests itself in this form of terracotta façade. In addition, the ceramic, as a natural, stable building material designed for a very long life, is equipped with virtually unlimited resistance to rain, frost and chemical influences. Thus, objects with these facades also prove to be role models in these respects. As for example the twin building of the Volksbank Weißenhorn shows. Who would have thought that one building had already been in existence for ten years, whereas the other building was erected only recently? As an ensemble, both appear to have been cast in one piece: the traces of time have simply passed by the natural terracotta.
