The lower levels of the structure were heavy and rusticated, recalling the work of H. H. Richardson from the previous decade, while the spandrels of the upper stories emphasized the building's verticality. The frame for the stone structure was largely made of iron and steel, and on the interior the structural techniques were often displayed by balustrades and columns that in places revealed the rivets that held them together. The formal style of the building was altogether not unlike that of Furness's building for the Pennsylvania Academy of the Fine Arts, which he completed in 1876, or his University of Pennsylvania Library, designed in 1888.
