The Chicago Architecture Foundation (CAF) is a nonprofit organization dedicated to advancing public interest and education in Chicago's outstanding legacy of architecture and design. CAF presents architecturally focused tours, exhibitions, lectures, special events, and education activities. The design of the CAF outlet seamlessly integrates a blend of various Chicago architectural iconic elements, spanning from the 1880's 'Sullivanesque' columns to a curved modern ceiling element. Locally produced and sustainable 'green' materials are used throughout.
