Façade and roof of a building have the ability to tell stories. Stories about its use, its inhabitants, its architects. To choose the right material for the design is most important for the visual aspect. Clay building materials combine longevity and versatility with classic, timeless and at the same time modern appearance. They give architects numerous innovative application possibilities and enable exciting aesthetic solutions. This issue of architectum shows impressive projects from eleven countries - from single-family homes to public buildings - which illustrate what is possible with clay building materials. Wienerberger is proud to provide natural building materials that are versatile, energy efficient, durable and simply beautiful.
