The zigzagging form of this new bank headquarters serves to maximize both the length of the facade and the office area of a building located on a narrow site between railway land and the river. This layout also articulates the three upper floors into flowing yet distinct spatial realms.

The central spine of the 13- to 20-metre-deep office areas consists of a series of sculpturally curved cores, partly in concrete, partly in a dry form of construction. Containing staircases and ancillary spaces, these structures are distinguished by stencilled designs by the artist Esther Stocker.

Integrated in so-called “Bergundtal” furnishing strips are storage facilities, seating and plant containers. Of changing height, the strips serve to screen off working areas, while nevertheless allowing interesting views out. The 330 workplaces along the two facades are arranged in fixed groups of four, and the rows of tables are articulated by modular elements that house a sitting recess, a phone cabin and a small discussion space.
