The former Cook County Hospital building will survive for another month, as the vote to determine whether to save or demolish the structure is deferred. The commisioners voted 10-7 to defer a demolition vote so developers have a chance to show what could be done with the building. Developers would like a chance to rehab the 89-year-old building, and preservationists made an impassioned plea to keep a building they call architecturally and historically unique to Chicago. Maintaining the structure is getting tough, so the developers must come up with some solid plans before a vote next month.
