Drees & Sommer in Switzerland - since 2008

These days, you would describe Drees & Sommer’s early days in Switzerland as a classic start-up story of a small, highly motivated, and very capable team facing a huge challenge. Although the firm’s first office wasn’t quite in a garage like Apple, it wasn’t far off. Driven by their shared vision, the Drees & Sommer team managed to successfully execute two major, high-profile projects in Switzerland in the first few years: the five-star superior hotel The Chedi in Andermatt and the Bau 1 office block for F. Hoffmann-La Roche AG in Basle.

These flagship projects were followed by others and, as the number of employees grew, so too did the firm’s range of services. The company initially focused strongly on general planning and construction management services, but has steadily built up its engineering expertise in recent years. RBS Projektmanagement (Schweiz) GmbH became a subsidiary in 2016, further expanding the firm’s service portfolio. This also means that it can now support interesting, forward-looking workplace consulting projects from within Switzerland. The company took the final step in completing its range of services with its takeover of RESO Partners AG. With the help of its new real estate consultants, Drees & Sommer Schweiz AG can now offer comprehensive services from a single source, covering the whole life cycle of real estate from a wide range of sectors.


Drees & Sommer - the full corporate history

In 1970, Gerhard Drees founds a small engineering firm in Stuttgart. He and co-founder Hans Sommer never dreamt that the three-person team would one day become a company operating internationally with more than 3,820 employees. Today, just as then, innovation and thinking differently continue to be the hallmarks of Drees & Sommer. Here you will find more background information on the corporate history of Drees & Sommer.
