Drees & Sommer exists to create a future worth living by transforming how the built environment is designed, constructed, and operated. The construction and real estate industries account for nearly 40% of global carbon emissions, yet traditional approaches remain fragmented, inefficient, and unsustainable. Drees & Sommer tackles this challenge head-on by providing integrated consulting and implementation services that unite vision with reality - delivering projects that are economically viable, ecologically responsible, and digitally enabled.
Since 1970, the company has grown from a small Stuttgart engineering office into a global partner-managed consultancy with 6,500 professionals across 70+ cities. Their interdisciplinary teams work on 6,872+ projects worldwide, uniting apparent opposites: tradition and innovation, economy and ecology, analog and digital, efficiency and well-being. As a sustainability pioneer and digitalization driver, Drees & Sommer doesn't just advise clients - they implement solutions that measurably reduce environmental impact while creating lasting value. From carbon-neutral buildings to resilient infrastructure and future-proof industrial facilities, they're proving that sustainable development isn't just necessary - it's the foundation of competitive advantage in a changing world.
