HOK (firm). HOK is a global design, architecture, engineering, and planning firm, originally founded in St. Louis, Missouri. It is one of the largest architectural firms in the world, with a portfolio encompassing a vast array of project types including sports stadiums, airports, healthcare facilities, and corporate headquarters. The firm is renowned for its integrated design approach and sustainable practices, having played a significant role in shaping the built environment across six continents.

History

The firm was established in 1955 by architects George Hellmuth, Gyo Obata, and George Kassabaum, whose initials formed the original name Hellmuth, Obata and Kassabaum. Its early work included major projects for the United States Air Force and NASA, such as facilities at Cape Canaveral. A pivotal moment came with the design of the iconic National Air and Space Museum in Washington, D.C., which cemented its national reputation. Throughout the late 20th century, HOK expanded globally, opening offices in cities like Hong Kong, London, and Shanghai, and merging with the CRSS group in the 1990s to bolster its engineering capabilities. The firm officially rebranded to HOK in 2013, reflecting its unified global identity.

Notable projects

HOK's portfolio includes many landmark structures worldwide. In sports architecture, the firm designed Mercedes-Benz Stadium in Atlanta, Truist Park in Cumberland, Georgia, and the renovation of Lambeau Field in Green Bay, Wisconsin. Its aviation work features major terminals at San Francisco International Airport, King Khalid International Airport in Riyadh, and Chhatrapati Shivaji Maharaj International Airport in Mumbai. Significant corporate and institutional projects include the Burj Al Arab interiors in Dubai, the U.S. Embassy in Ottawa, and the LEED Platinum-certified NASA Sustainability Base at Ames Research Center. The firm also designed the Moscow School of Management SKOLKOVO in Russia.

Design philosophy and practice

The firm's philosophy emphasizes integrated and evidence-based design, often utilizing advanced tools like Building Information Modeling and performance analytics. A core tenet is sustainable design, with HOK being a signatory to the AIA 2030 Commitment and a leader in creating high-performance buildings that target net-zero energy and water use. Its practice is organized around specialized studios focusing on sectors such as Aviation + Transportation, Sports + Recreation + Entertainment, and Science + Technology. Collaborative research initiatives, such as those with the Biomimicry Institute, inform its approach to resilient and regenerative design.

Leadership and organization

Following its founding trio, leadership transitioned to a new generation, with Bill Hellmuth serving as Chairman and CEO until his passing in 2023. The firm is structured as a limited liability partnership with a board of directors overseeing its global operations. HOK maintains a network of over 20 offices across the Americas, Europe, and Asia, each led by managing principals and design directors. Key leadership figures have included former presidents Clark Davis and Patrick MacLeamy, who helped steer the firm's international expansion and its focus on building performance.

HOK has received extensive recognition from prestigious institutions within the design industry. It has been honored with numerous awards from the American Institute of Architects, including the AIA Committee on the Environment Top Ten Awards for projects like the Global Ecology Research Center at Stanford University.
