Chicago Blue Cross Blue Shield to Build a 24-story Addition Atop its 33-story Headquarters
Blue Cross and Blue Shield of Illinois will add 24 floors on the top of its existing 33-story headquarters building in Chicago to accommodate the health insurer's rapid growth. Health Care Service Corp., parent of Blue Cross and Blue Shield of Illinois and co-occupant of the building, said last month that the $270 million construction project will begin early next year, upon approval of various permits. The structure was originally designed by Chicago architect James Goettsch to accommodate the 24 additional stories to meet an expected need for more office space. The building's height will increase from the current 466 feet, to 796 feet.
