SBB CFF FFS

New Headquarter, Bern

Result of a successful joint competition In collaboration with Lussi & Halter Architects, Lucerne

During the Renaissance — that era in which architecture was regarded as the highest form of expression of the alma mater — the roles of architect, artist, and sculptor were united. A similar, though contemporarily restrained and holistic attitude characterizes the construction of the two SBB office buildings.

The central element of their appearance is the suspended, movable façade made of colored glass fins called “GIRASOLE,” which wraps around the building volumes like a garment. Around 1,800 fins respond to the position of the sun, weather conditions, and incoming light, adjusting themselves to ensure an optimal indoor and working climate. As a result, the buildings’ appearance changes continuously — over the course of the day as well as throughout the year.

The façade design is based on just five metallic color tones. Across all five stories, these unfold into a meandering color composition that encircles both buildings, without identical color combinations ever touching.
