HAVE YOU EVER WALKED BY A BUILDING AND THOUGHT I WISH I COULD SEE WHAT'S INSIDE?

The Chicago Architecture Center's Open House Chicago (OHC) is the city’s annual architecture festival. For one weekend in October you can explore Chicago’s most iconic and unique architectural treasures. From mansions to sacred spaces, theaters to private clubs, hotels to secret rooms-OHC gives visitors a behind-the-scenes look at many of the city’s great spaces that are rarely, if ever, open to the public.

Here’s your chance to venture into new neighborhoods, learn the stories of Chicago’s buildings and experience the rich and diverse cultures of our community.

OHC is completely free-of-charge-no registration or tickets are needed. So gather your friends, plan your itinerary and mark your calendar for October 19-20, 2019!

Volunteer Greeters are assigned to all OHC sites to welcome and count guests, answer questions and assist with crowd control and line management. Greeters typically work one four-hour shift, which leaves plenty of time to explore the city the remainder of the weekend.

Leadership Volunteers help us keep OHC running smoothly by working a full-day shift, overseeing either a cluster of nearby sites, or one particularly busy downtown site.
