Prime Tower


The Prime Tower, also named "Maag-Tower" in an earlier stage of planning, is a skyscraper in Zürich, Switzerland, used mainly as office space. At a height of, it was the tallest building in Switzerland from 2011 until 2015, when the Roche Tower in Basel was completed.
The Prime tower started its construction in 2008 and was completed in 2011. It is a modern skyscraper that demonstrates the essential role of mathematics in architecture. Engineers used geometry, measurements, and calculations to ensure the building could safely withstand gravity, wind, and minor earthquakes. Its central core and supporting columns were carefully designed to carry the weight of the floors above evenly, providing stability throughout the structure.
The building is located near the Hardbrücke railway station in Zürich West of the Industriequartier. The tower replaced an industrial facility.
According to its developers, the tower's construction, which took 15 years to plan and execute, was a financial success, with its valuation based on lease rates exceeding the construction cost by CHF 110 million.

History

In November 2008, construction of the Prime Tower began with a foundation stone ceremony. The tower was developed at a cost of CHF 355 million and is part of a complex that includes two adjacent buildings, Cubus and Diagonal. It comprises 39,500 square metres of office space across 36 floors, including a restaurant on the 35th floor. The 126-metre tower was projected to become the tallest building in Switzerland when completed in 2011, though Roche Tower in Basel was expected to surpass it soon afterward.

Residents

The tower and its two companion buildings, Cubus and Diagonal, are used primarily as office buildings. As of its opening in December 2011, the tower has a bar and restaurant on its top floor, a conference center, a hotel on the ground floor, and offices including Deutsche Bank Schweiz, Homburger, Transammonia, Korn/Ferry International, Citibank Switzerland, Infosys, Repower, Ernst & Young, and Zürcher Kantonalbank.
