131 South Dearborn Street – Citadel Center

Architect: Ricardo Bofill / 1,500,000 sf

Developed by Beitler and Prime Group Realty Trust, Citadel Center was designed as Chicago’s first true technology inspired building. It was the first building in Chicago to incorporate the 14-inch raised floor system allowing for both data and HVAC to function under the floor. The raised floor system has contributed to the reduction in “churn” and operating costs for Citadel Center’s tenants and attracted two of Chicago’s most technologically advanced tenants – Bank One and the Citadel Investment Group LLC.
