Five decorative marble columns –representing classical orders of architecture – stood for several years as a placeholder for the future site of the Architecture building. The 23-foot stand-alone columns were later incorporated into the newly built Knowlton Hall, which was dedicated in 2004.

Knowlton Hall is home to the School of Architecture, which includes the disciplines of architecture, landscape architecture and city and regional planning. The building was named after OSU alumnus Austin E. Knowlton, who donated $16 million to the school in 1994. The 165,000-square-foot facility includes classrooms, auditorium, studio and gallery spaces, a library and a rooftop garden.

Knowlton Hall has received several design awards, including the Architecture Honor Award from the American Institute of Architects, which is the profession’s highest recognition of works that “exemplify excellence in architecture, interior architecture and urban design.”

Knowlton Hall was built on the site of the old Ives Hall (demolished in 2002), which housed the Department of Food, Agricultural and Biological Engineering, and had also been the home to Architecture’s student design studios.
