The curtain goes up at 640 North Wells in River North.

In The War On Wells, 640 North Wells lost the first-glass prize to The Gallery On Wells across the street. But not to worry. 640 rallied, and came back with a curtain wall of its own, one that gleams on sunny days. For now, two rows of glass have moved into the tower. Soon, all 23 stories and 251 units will glisten in the sunlight, as JDL Development moves toward a Summer 2017 opening.
