It was designed in 1912 and built between 1912 and 1915.","why_significant":"The nomination argues it is the last building to come from D.H. Burnham's office before his death on June 1, 1912, and a transitional work between D.H. Burnham & Company and Graham, Burnham & Company. Its rounded corners on a square plan are described as a unique feature, and it was built for the Estate of Marshall Field, a major Chicago real estate investor.","narrative":"Rising twenty-one stories at Clark and Washington streets in the Chicago Loop, this office building with ground-floor shops was designed in 1912 by D.H. Burnham & Company and completed in 1915 by Graham, Burnham & Company. Its steel frame rests on 104 concrete caissons carried 110 feet to bedrock, and offices surround a large light well. Granite clads the lower floors, while gray terra cotta carries bands of palmette and fleur-de-lis ornament above. Its most distinctive feature is the set of rounded corners, unusual for a square plan. The building is considered the last to emerge from Burnham's office before his death in 1912. It was built for the Estate of Marshall Field on a site once occupied by a church, a music hall and the Chicago Opera House. A 1945-1947 remodeling filled part of the light well and changed the entrance, and restoration of those spaces was under way when the nomination was prepared.","period_of_significance":"1912-1915","architect_builder":"D.H.
