About Drees & Sommer

Drees & Sommer SE is a partner-managed consulting firm that specializes in advising on and implementing sustainable, innovative and cost-effective solutions in the real estate, infrastructure and industry markets - or offering clients both from a single source.

The company’s interdisciplinary teams are involved in around 6,500 projects worldwide, working to create a livable future and unite concepts which can at face value appear to be opposites: tradition and future, analog and digital, efficiency and well-being.

Company History

In 1970, in Stuttgart, Gerhard Drees founded a small engineering company. At that time, he and his co-founder, Hans Sommer, could never have imagined that their three-person team would grow over time into an international company with more than 6,000 employees. To this day, Drees & Sommer continues to be characterized by the ability to innovate and to "think outside the box".
