360 West Erie has to go, making room for Three Sixty West. It’s the new math.

A demolition permit was issued Tuesday for the humble 2-story building at 360 West Erie in River North. Yeah, that rooftop deck is cool, but it has to go. If the address sounds familiar to you, it may be from the buzz going ’round about Three Sixty West, the new condo tower coming to the block from Belgravia Group (think Renelle on the River). Designed by GREC Architects, Three Sixty West will feature 38 condominiums in an 12-story building.

Quality Excavation will do the ripping apart of the old building; when construction time begins, Maris Construction (they’re putting the finishing touches on Belgravia’s CA Washington development) will be on the build.

12 stories? Yep, Maris should land on the tower crane count soon.
