Infinite Chicago

28 E. Jackson Blvd., Chicago, Illinois / United States of America

The conversion and renovation of Chicago’s landmark 19-story Steger Building (1910), and the 16-story Gibbons Building (1912) designed by Marshall & Fox Architects, and the iconic Pickwick Stables Building (1800’s) located between the two structures into a mixed-use student housing and retail complex. The complicated adaptive re-use scheme honors the historic legacy of the buildings while maximizing the development opportunity. Street-oriented commercial functions are maintained at the ground level with service and amenity functions on the second floor and resident access through the Steger Building lobby. Modern accessibility and life safety codes are addressed by joining the buildings with a connecting bridge at all floors above the 5th level. The roof of the Gibbons Building is improved with an outdoor terrace and event room addition with height and massing coordinated for compliance with historic site line requirements. The masonry clad steel frame buildings have had fire escapes removed and their facades carefully restored. Technical hurdles included; a neighboring building with an access easement, zero lot line setback conditions, sidewalk vaults, elevated commuter tracks and party walls that limited windows and ventilation options, and landmark requirements mandating preservation of historic elements and the reconstruction of a missing 5-foot terracotta cornice.
