Tadao Ando‘s buildings stand for archetypal architecture. Karlsruhe is now home to such a solitaire: the new headquarters of the Weisenburger corporate group. Here, even the smallest details corridors in the event of an emergency but should otherwise be as invisible as possible, also require precise planning.The sliding doors („Teckentrup 62 FST“ EI290) offer the highest technical level: they effectively protect against fire and smoke. With their cool, modern industrial look, the construction elements blend harmoniously into Ando‘s architectural language.
