History

HOK was established in 1955 in St. Louis during a period shaped by post‑World War II development and modernist architecture trends associated with figures like Mies van der Rohe, Le Corbusier, and Frank Lloyd Wright. Early commissions included projects for regional institutions such as Washington University in St. Louis and municipal developments tied to St. Louis County planning initiatives. In the 1970s and 1980s HOK expanded nationally with offices opening in cities including New York City, Los Angeles, San Francisco, and Chicago, positioning the firm alongside peers such as Skidmore, Owings & Merrill, Kohn Pedersen Fox, and Perkins+Will. International growth in the 1990s and 2000s led to offices in London, Dubai, Singapore, and Sydney, and collaborations with institutions such as University College London, Sheikh Zayed Grand Mosque Centre, and Singapore National University. Leadership transitions have connected HOK to professional organizations including the American Institute of Architects and initiatives like the U.S. Green Building Council.
