The original portion of the 1955 Denver Public Library, a five-story, flat-roofed, reinforced concrete frame building, with its random ashlar Indiana limestone veneer, is a significant International Style building designed by Burnham Hoyt. The library is the only major work by Hoyt completed in Denver in the post-World War II period and is the only one of two major Hoyt projects in the International Style that survives. Princeton, New Jersey, architect Michael Graves, with the Denver architectural firm of Klipp Colussy Jenks DuBois, designed the seven-story 1995 addition. The library is an integral component of the National Register Civic Center historic district.
