The record, newest first

  1. Digital Realty's project page describes a next-generation facility under construction across the street at 330 E. Cermak, and its Chicago location page lists 350 E. Cermak (ORD10) at about 1 million square feet. (Digital Realty, Oct. 22, 2026; Digital Realty, Oct. 22, 2026)

  2. Prairie District residents and a neighborhood alliance organized against the second building, citing noise, shade and power demand; the 3rd Ward office held community meetings. (CBS News Chicago, Sept. 6, 2023)

  3. The developer cut the planned height to 271 feet and the floor area ratio from 10 to 7; a 2014 planned-development approval for the site had lapsed, so Plan Commission, zoning committee and council review were needed again. (Urbanize Chicago, April 13, 2023)

  4. A Digital Realty affiliate, Digital Lakeside 3 LLC, filed with the City Council to rezone the vacant lot at 321-337 E. 21st St. for a 565,000-square-foot, 13-story data center linked by bridge to 350 E. Cermak. (Data Center Dynamics, Sept. 23, 2022)

Conflicts and open questions

  • Coordinates approximate, from the 350 E. Cermak address.
  • No 2024-or-later public record found confirming that the City Council approved the 321-337 E. 21st St. building.
  • The sources do not establish whether the 330 E. Cermak facility on the operator's project page is the same project as the 21st Street proposal; CBS describes 330 E. Cermak as the American Book Company building.
  • sqft is the operator page figure (1,005,500); Data Center Dynamics gave 1.1 million in 2022.
