It was built for the Sigma Chapter of Alpha Gamma Delta on land purchased in 1927.","why_significant":"The house is part of a group of fraternity and sorority houses near the University of Illinois Urbana-Champaign campus. The nomination covers the building's architecture and the history of Sigma Chapter, a prominent campus women's fraternity in the 1930s. The excerpt does not give the full significance statement, so the exact criteria argument is not fully visible.","narrative":"Alpha Gamma Delta's Sigma Chapter built this three-story fraternity house at 1106 South Lincoln Avenue in Urbana, on land bought in 1927 to replace an earlier residence. It sits on the street that marks the eastern edge of the University of Illinois campus, beside the Kappa Kappa Gamma house, which it deliberately mirrors in the placement of its service areas. The building is a French Revival design with gray taupe concrete brick walls, steeply pitched hip roofs of slate, half-timbered upper stories, steel casement windows, and a circular stair tower beside a Tudor-arched entry porch. Additions in 1965 changed the original L-shaped plan into a T shape while matching the original materials and design. The house is part of a multiple-property group of fraternity and sorority houses at the university. Records describe Sigma Chapter in the 1930s as one of the leading sororities on campus, with active members in scholarship, athletics, music and student publications, and the new house served as its showplace.","period_of_significance":null,"architect_builder":null,"architectural_style":"French Revival","criteria":[],"status_note":"Still used as a chapter house (education-related housing).
