Renelle on the River went up in a hurry. Now, the concrete is topped out, and without any glazing yet, it looks kinda skeleton-like. But that will change soon, as McHugh Construction focuses on getting the outer skin installed and interior work begins. (Then again, maybe that’s what they’re calling an “open floor plan” these days. No windows, no cladding, just you and the elements and your living room.) The bKl Architecture design brings 50 new condos to the River North neighborhood across 18 stories.
