It rises 475 feet or 145 meters above Downtown Pittsburgh. Its address is Grant Street & Seventh Avenue. It is the best example of Art Deco construction and ornamentation in Pittsburgh. It is constructed with Indiana limestone with a polished granite base and dark copper roof. Inside the Koppers Tower the lobby is richly decorated with marble walls. Its copper roof is pitched in a chateau-like design and is illuminated at night. The building was designed by the architectural firm of Graham, Anderson, Probst & White. In February 1948, Equitable of New York purchased the building for $6 million ($ million today).〔http://digital.library.pitt.edu/cgi-bin/chronology/chronology_driver.pl?q=koppers+building&year=&month=&day=&start_line=0&searchtype=single&page=sim〕 File:Koppers Building cropped.jpg|Top of the structure.
