 The eight-story building itself was designed in 1908 by architects Colbert A. MacClure and Albert H. Spahr, who also designed many prominent buildings in Pittsburgh, such as the first section of the William Penn Hotel and the Keystone National Bank.The original, eight-story building was completed at 200 Ross Street by 1908.Due to the Jones and Laughlin Company’s prosperity, the company commissioned an additional five stories to be added to the building in 1917, which were also designed by MacClure and Spahr.
