The office complex in Karlsruhe is considered as Tadao Ando’s first urban design in Germany. The publication provides exclusive insights into the creation and planning of the building. Architecture photographs and building plans show Ando’s design formula: reduction to the essentials, exposed concrete on the scale of the tatami mats, strict geometries, precision and refined detail give the building its characteristic touch. The architect and client agreed on creating an aesthetic and energy-efficient building that meets the latest technical standards and offers the employees the best working conditions.
