Andreasturm

Short description

SBB Real Estate, the real estate division of the Swiss Federal Railways, is constructing the Andreasturm in the Zurich-Oerlikon district. The 80-metre-high office building is situated on a triangular plot of land between two main tracks in the north-eastern section of the train station and the Amstein-Walthert building.

The project

The Andreasturm high-rise building is designed to contain an office building with a staff canteen and conference area for the anchor tenant on the first floor, along with retail or catering spaces for the general public on the ground floor. The basement levels contain storage areas, bike parks, the technical building services and the parking garage. Thanks to its prominent location and its height of some 80 metres, the Andreasturm will be a real landmark at Oerlikon station.
