Allstate Corp.’s suburban campus outside Chicago, with its interconnected buildings, manicured grounds and acres of parking, represented a new vision for the U.S. office when it opened in 1967. That vision is now dead.
The insurer reached a deal last month to sell most of the campus. The new owner plans to demolish the office buildings and convert the Northbrook, Ill., site into more than 3 million square feet of e-commerce warehouses and other logistics facilities.
