Your innovative partner for consulting, planning, construction and operation

For more than 45 years, Drees & Sommer has supported public- and private-sector owners and investors in all aspects of real estate. Managed by partners and headquartered in Stuttgart, the company has 40 national and representative offices worldwide. The focus is always on profitability, whereby we promote sustainable building to the greatest possible degree. We call this approach ‘the blue way’.

The construction and real estate experts always have the goal of producing measurable added value for the client. This could mean, for example, streamlining the implementation of a construction project, making the operation of a property more economical, or cutting energy costs through innovative concepts. Currently, the company with its approximately 2,150 employees is acting as an independent project manager for more than 960 construction and real estate projects.

Drees & Sommer and EPEA Internationale Umweltforschung Hamburg are jointly committed to Cradle to Cradle®, bringing principals, investors, architects and manufacturers together to promote the approach.


"the blue way"

‘the blue way’ is the approach that Drees & Sommer takes to all services. Combining economy and ecology and thus reducing investment and operating costs while enhancing functionality and process quality – as well as taking design, health, well-being and user-friendliness into account – are the goals for all projects. Only in this way can value-add be secured for the principal over the entire life cycle of the property.
