The new headquarters of the insurance company ÖKK Versicherung in Landquart, designed by the architects Bearth & Deplazes, fascinates the beholder with its supporting structure of whitecoloured precast concrete elements. This exterior supporting layer is combined with a fully-glazed facade behind it. Concrete arches of identical design to those outside demarcate an atrium in the interior. The offi ces and conference rooms were designed with System 3400 partition walls. This fully-glazed system with minimal cross sections is incorporated into the room-defining round arches as a fullygazed structure, in a similar way to the facade.
