Adding urban density to the existing train station area in Winterthur, a two-phased series of buildings is proposed parallel to the train tracks. Functions include two levels of generous bicycle parking, ground floor retail spaces, and office space above. The buildings will form an edge to the tracks, thus reinforcing the street life of the city.

Volumetrically, the buildings are conceived as four stacked volumes that slip past one another. The first is the retail base and underground technical functions, followed by a street roof filled with mechanical functions, 1 meter thick in height and to be wrapped graphically by a collaborating artist. Above this are 3 levels of office buildings with standard façade articulation, and four double story penthouses. The shifted layers each use different façade materials.
