Not sure it's been mentioned on here, but John Ronan was tapped to design the Park District's new headquarters and parkland at 48th/Western, right next to the Western Ave Orange Line stop. They just filed the PD this week.
Ronan wisely flipped the site plan from earlier sketches, and put the HQ building close to Western with the entrance oriented towards the Orange Line stop, and the parkland further west on the neighborhood side.
The building looks pretty cool... actually two interlocking buildings, the headquarters and a fieldhouse, that together form a circle. The material palette would be pretty nice, bronze glass behind expanded metal screens that give a scalloped appearance, and Chicago common brick feature walls at the entrances.
