One Chicago (building)

One Chicago (formerly One Chicago Square) is a skyscraper in the River North neighborhood of Chicago. It reaches 971ft and is among the tallest buildings in Chicago.

History
The building's site previously held a parking lot owned by the Catholic Archdiocese of Chicago. The Archdiocese began seeking a development partner to build a structure on the site through real estate-focused investment bank Eastdil in 2016. The development was approved by the Chicago Plan Commission in 2018. The building topped out in 2021.

In April 2019, the developer JDL announced that the project name was changed from "One Chicago Square" to "One Chicago" to better connect the property to its address of 1 West Chicago Avenue.

Design
Goettsch Partners and Hartshorne Plunkard Architecture designed the buildings. The complex contains two towers connected by a central podium. When completed, the taller of the two towers was to be the eighth-tallest structure in Chicago with an anticipated 78 stories, although a final height was determined and a spire may have been added to the design.

Usage
The project is a mixed-use development, though primarily residential, with 812 residential units.

Planned retail tenants for the podium of the two towers include a Whole Foods Market and Life Time luxury athletic resort, as well as an upscale restaurant and an event center catered toward receptions for weddings at Holy Name Cathedral.

The building contains 735 apartments, 77 condominiums, 55,000 sq ft of office space, 188,000 sq ft of retail space, and a Life Time Fitness center.
