Prime Tower

With a height of 126 meters and its extraordinary architecture, the Prime Tower is one of the highest buildings in Switzerland and provides for a distinctive urban highlight.


The Prime Tower, which opened in 2011, has 36 floors. It offers room for around 2,000 working spaces, a conference center and a public restaurant and bistro on the two top floors, as well as a Café-Bar on the ground floor. The imposing tower with its two annex buildings "Cubus" and "Diagonal" is the winning project in an international competition. Several renowned architectural firms were invited to submit, with the winning project from the Zurich based architecture office Gigon | Guyer. The office building "Platform" completes the ensemble.

The form of the ground layout is an irregular octagon which, contrary to the usual perception of high-rise buildings, expands upwards. The exterior consists of frameless window elements which can partly be opened and give the building a multifaceted appearance of a green crystal. Through the polygonal form of the ground layout and the allocation of the workspaces around the core of the building, a maximum of ideally exposed workspaces is made possible. Also, from an energy and technical point of view, the Minergie certified building fulfills the highest standards and carries numerous environmental labels.

The Prime Tower marks the up and coming neighbourhood Zurich-West which has evolved from the former industrial district to a promising living and working area.
