About Open House Chicago

Now in its 11th year, Open House Chicago is one of the largest architecture events of its kind in the world. The free festival typically offers access to hundreds of sites across Chicago, from iconic locations to under-the-radar architectural gems.

Last year, the event was reformatted for outdoor and online participation to accommodate for social distancing. The Open House itineraries focused on larger themes — forgotten or under-celebrated architects, how community areas develop specific architecture styles, and important places for understanding the city’s history with an emphasis on the South and West sides.
