Additional Information:A 'site file' exists for this property. It contains additional information such as correspondence, newspaper clippings, or historical information. It is a public record and may be viewed in person at the Wisconsin Historical Society, State Historic Preservation Office. This is a late Prairie School house designed by Louis H. Sullivan and assisted by George Grant Elmslie and Louis W. Claude and built in 1909. It is the only surviving house from the latter stage of Sullivan's career.[A]. Between 1905 and his death in 1924, Louis Sullivan created only two residences. One was this house, designed with George Elmslie, who was then Sullivan's chief draftsman and assistant. Sullivan was one of America's most important architects of the time; many consider him second only to his protégé Frank Lloyd Wright. Elmslie, who produced the working drawings and designed the windows, interior furnishings and fixtures, and other details, became an important architect in his own right. When this house proved too large for the Bradleys to maintain, they asked Elmslie to design a new house in 1914. Sullivan was the spiritual leader for the Prairie School, and the Bradley House is undoubtedly the most important Prairie building in Madison. The style was uniquely American. The long, low mass of the Bradley House’s south elevation, as well as the ribbons of windows, evoke the horizon, but the brick piers anchoring the building establish a clear sense of vertical movement. They also serve as springboards for the dramatic cantilevered sleeping porches on the second floor. The massive wooden brackets that seem to support these porches actually do not--they conceal weight-bearing steel beams underneath. But the huge brackets draw attention with their geometric carvings and elaborately sawn ends. Multicolored leaded windows, divided into small vertical panes, also typify the Prairie School. Inside the house, Sullivan and Elmslie’s design included large playrooms and numerous children’s bedrooms. Many years later, these made the house well suited for use by a fraternity. After a 1972 fire, Sigma Phi employed local architect Mark Purcell to oversee a faithful restoration. Changes to the original design have included enclosed sleeping porches and the porch off the dining room. Madison Landmark: 5/18/71, and National Historic Landmark: 1/7/76. Also part of the University Heights Historic District (NRHP 12/17/82). Bradley, a chemistry professor at the University of Wisconsin, lived here from 1911-1914. Sigma Phi Fraternity acquired the property in 1914.
