Architects: Graham, Anderson, Probst & White The Koppers Building is one of the best examples of an Art Deco-style building in Pittsburgh. This stepped-back skyscraper is encased in limestone and crowned with a copper chateauesque roof. The lobby provides an excellent example of an elegant and urbane Art Deco interior. The architectural firm was the successor of D.H. Burnham and Company, which designed several Pittsburgh buildings in the Classical and Beaux Arts styles.
