Ready for more construction in the West Loop? Good. Because Tuesday, Union West got its full-build permit for a 15-story residential tower at 939 West Washington Boulevard. Building atop the foundation permitted back in April, the 939 tower is the first of two structures at Union West that will ultimately contain 357 apartments, with 12,000+ square feet of ground-floor retail space and 255 parking spots.

bKL Architecture designed the two-tower development for ZOM Living. Power Construction is the general contractor, adding to their West Loop projects that include the Hoxton Chicago, 333 North Green, 180 North Ada, Milieu, and 900 West. (Wow. They’re really busy.)

There’s a cool-looking iron contraption on the site now. No idea what that’s about, but we’re pretty sure it’s structural and not sculptural.

And now, the photo gallery, with everything from that cool steel thing, to bKL Architecture renderings, to demo work, to now-removed buildings and parking lots.
