Citadel Center, completed in 2002 by the architectural team DeStefano + Partners and Spanish architect Ricardo Bofill of Taller de Arquitectura, presents a striking design that evokes the grandeur of classical architecture. The 37-story building features a design reminiscent of a classical column with a solid base, highlighted by a projecting cornice at the roofline and elegant curved silver glass walls.
In 2018, a major redevelopment of the Dearborn lobby was undertaken to enhance the space for modern needs. This renovation included improvements to security, the redesign of key finishes to elevate the aesthetic appeal, and technology upgrades to the elevator systems, ensuring the building meets the demands of today's occupants while maintaining its architectural integrity.
Taking inspiration from the original lobby design, the updated finishes were chosen to celebrate the building’s unique identity. The new stainless steel and stone finishes reflect the integrity of the original architecture while offering a sleek and stunning presentation for today’s occupants and visitors.
The building was the first in Chicago to utilize a raised-floor pressurized plenum system, allowing the efficiency of under floor air circulation and personal climate control through floor mounted diffusers. This benefits occupants by allowing fresh air to suffuse their entire floor-to-ceiling space, and studies have shown this results in a healthier working environment. Citadel Center was designated LEED Gold EB Gold in 2017 and contains a 13,000 square foot green roof to reduce rainwater runoff and heat island effect. The building is also Energy Star certified.
Citadel Center is a 1.5 million square foot Class A premier mixed-use tower, opened in 2003. The building address is 131 South Dearborn Street, Chicago, Illinois 60603. The property has approximately 1.4 million square feet of office space and 100,000 square feet of retail space. The property also includes a 211-space public parking garage.
The Building stands between two subway lines at the nexus of Chicago's public transportation system, with buses and trains in every direction. The Building is located within easy walking distance of Metra trains from both the Ogilvie Transportation Center, Union Station, and the South Shore Line. Its excellent location is in close proximity to City and Federal offices, hotels, restaurants and the Theater District.
