EHDD is an architecture, interiors, planning, and urban design firm founded in 1946 in San Francisco; a city renown for embracing ideas that envisage the future. This ethos has informed EHDD’s work since its beginning, resulting in forward thinking designs that last for generations. We believe it is possible to design a collectively greater future for our clients, society and the environment. Our commitment has been recognized with the prestigious AIA (American Institute of Architects) National Firm of the Year award. EHDD is celebrated for its ability to envision spaces and places that excite our imagination, enhance our culture and inspire higher thinking. Whether its libraries or museums, science or academic buildings, aquariums or zoos, EHDD embraces each client’s mission to create the civic and cultural centerpieces that are the hallmarks of an advanced society. Many buildings from the firm’s early years remain landmarks in our lives today, and will continue to enrich our society for generations to come—a testament to the timeless nature of visionary, user-focused design. EHDD’s leadership in sustainable design is exemplified by our 10 LEED Platinum projects, 16 LEED Gold projects, and 2 LEED Silver projects. EHDD has also designed two of the eight Net Zero Energy Certified projects – The David and Lucile Packard Foundation office building and IDeAs Z2 Design Office in San Jose, California. The Exploratorium at Pier 15 is on track to become the largest Net Zero Energy museum in the United States. EHDD has also won five AIA National Committee on the Environment “Top Ten Green Projects” awards.
