The Larkin Building was designed in 1904 by Frank Lloyd Wright and built in 1906 for the Larkin Soap Company of Buffalo, New York. The five story dark red brick building used pink tinted mortar and utilized steel frame construction. It was noted for many innovations, including air conditioning, stained glass windows, built-in desk furniture, and suspended toilet bowls. Though this was an office building, it still caught the essence of Frank Lloyd Wright's type of architecture.
