Chicago is famously the city where cab drivers namedrop architects. This year there will be a new way for the general public to become even more well-versed in the city’s historic and contemporary architecture, openhousechicago. Modeled on successful programs in London, New York, and Toronto, openhousechicago will offer free access to more than 100 sites around the city, some of which are normally not open to the public, including the Center for Green Technology and the Burnham-designed Santa Fe Building. Organized by the Chicago Architecture Foundation, openhousechicago will run from October 14-16. Sites are still being nominated and volunteers are needed, so visit www.openhousechicago.org for more information or to get involved.
