Chicago’s bid for a spot on the global biennial circuit is getting its rollout this weekend.  


   At a preview press conference, coartistic directors Sarah Herda and Joseph Grima explained that they didn’t impose  a theme on the event. “We asked architects to tell us what is important,” Herda said, but some themes did emerge—among them, the need to take action in the world, the idea that no project is too small to matter, and the concept of “home.” The exhibits at the Cultural Center include four compact but full-size houses. 


 Jeanne Gang was on hand to talk about “Polis Station,” Studio Gang’s interesting alcove mural on the history of policing and their plan to turn police stations into community-friendly hubs.
