Things are getting formal now. Our friends at YoChicago have brought a new press release to light, announcing Atrium Village's planned development application with the city. The mixed-use, mixed-income plan calls for low-rises and four towers at 28, 36, 41 and 44 stories. Public green space is a component as well. The five-stage project will take 15 years or so to complete. Stroll back through Curbed's coverage for all the development info and renderings.
