First the cars were kicked out of the parking lot. Then the fencing went up. Then the Divvy station got kicked to a different curb. And now, there’s scraping and digging going on at 221 West Hubbard (and 412 North Wells, for that matter) in preparation for Centrum Partners’ two-building development in River North.

Designed by Hirsch Associates Architects, 412 North Wells will be a 9-story office building, next to 221 West Hubbard’s 23-story apartment tower.

Linn-Mathes, general contractor for both structures, must be champing at the bit to get going on this lot. It was hoped building permits would be filed around the first of April, but some soil samples turned up negative results, and that set things back awhile. But they’re up and running now. Jump on a Brown or Purple Line train and enjoy the fun.
