The Gogo Building, formerly known as the River Center, is an 840,000 square foot commercial building located at 111 N. Canal Street in the West Loop community area of Chicago, Illinois. Originally constructed as a warehouse in the early 1900s, the vintage, loft-style building is now home to various commercial tenants. It is a large red brick building along the Chicago River just south of where the river splits, formerly known as the Butler Brothers Warehouse building. It was designed for the Butler Brothers Company, a mail order company. The northern structure was designed by Daniel Burnham, and it was completed in 1913. (wikipedia.org)
