One South Dearborn is a 40-story, 828,538-square-foot office tower in downtown Chicago. Designed by the architectural firm DeStefano Keating Partners Ltd., the graceful architectural metal and glass tower culminates with a dual-crown lantern soaring 60-feet above the structure. A 16,000-square-foot outdoor plaza clad in Italian granite fronts Dearborn Street and provides entry into a three-story glass and marble lobby. Other amenities include an on-site fitness center, conference facilities, tenant lounge, shoe shine, concierge dry cleaning lockers, tenant bike share program, 8,000 square feet of retail space and four floors of above-grade parking that accommodates 170 vehicles. The project was completed in November 2005.
