Maris Construction is using this tower crane to build Three Sixty West in River North.

Maris Construction has one, and only one, tower crane in the skies over Chicago. And they’re making it count.

Three Sixty West, the 11-story condominium tower at 360 West Erie Street in River North from Belgravia Realty Group, has risen a floor above street level. The 38-unit, GREC Architects-designed development got its initial building permit back in November, and a tower crane permit this past January.

Those condos should be ready for move-ins early next year.
