The Koppers Building was commissioned by Andrew Mellon whose family had controlling interests in Koppers Company (now Koppers Inc).  The building was designed by the architectural firm of Graham, Anderson, Probst & White in 1927-29. The 35-story limestone building, with its external chateau roof (made of copper), its interior decorative bronze work, and colorful veined marbles. was designed in the Art Deco-style.

It has been referred to as one of the largest and best examples of Art Deco architecture of the 1920s and 1930s. Groundbreaking took place in November 1927, and the building was ready for occupancy in the spring of 1929. Originally owned and occupied by the Koppers Company, it became a multi-tenanted building in 1990.

It continues to serve as the headquarters location to Koppers Inc–now a market-leading wood-based technologies company–who occupies eight floors of the building.
