Construction progress continues at Centrum Hubbard in River North, the 23-story, 193-unit residential tower in River North from Centrum Partners and Hirsch Associates Architects. 412 North Wells, on the other hand, the accompanying 9-story, 41,000-square-foot office building next to it, still redeems itself as a convenient material-staging site for the apartment tower construction. To be honest though, it’s easier to observe and keep tabs on one project at a time, don’t you think?
