Designed by Adrian D. Smith of Skidmore, Owings & Merrill, the Franklin Center is one of the most famous and recognized buildings in Chicago.[1] The building's form features setbacks at the 15th, 30th and 45th floors. Designed in the postmodern architectural style, it is a granite-clad steel-framed building resting on pile foundations.[2] The structure is characterized by strong vertical lines, spiked roof pinnacles, granite cladding and setbacks. The granite is a deep red color at the base, but changes shade to rose-beige at the top.[12] Above the 5th floor, the lighter rose-beige granite is protected by silk-screened aluminum panels.[4] The building relies on Gothic detailing to showcase verticality.
