The new international headquarters of Médecins sans Frontières, designed by Berlin architects Sauerbruch Hutton, incorporates signage by CCHE Design. Minimalist, intuitive and flexible, the new wayfinding system has been designed to differentiate between "unchangeable" and "changeable" orientation information. Designed with a simple materiality that blends in with the architecture, the physical supports are combined with a QR code system to give users an exhaustive view of the building.
