Looking across the tracks at 333 North Green.

Office buildings are a big deal in the West Loop these days. No longer confined to The Loop, Chicago’s professional palaces are sprawling out to other neighborhoods now, and the West Loop leads the way. Not surprising, as this part of town seems to be out in front of most every aspect of development.
