Initial caisson and foundation preparation can be seen for a 16-story commercial building at 311 W Huron Street in River North. This upcoming retail and office building, planned by North Wells Capital, had scored $88 million lease with the major tenant Spins earlier this year, jumpstarting the now-underway project. The company will take up occupancy in the top three floors of the 226-foot-tall building. The edifice is replacing a former parking lot just west of the elevated Chicago Transit Authority L tracks. Since the last update, a tower crane permit has also been issued, adding to a new pocket of cranes in the northwest corner of River North once it’s installed in the coming weeks.
