About 300 East Randolph

Location: Chicago, Illinois
Developer: Walsh, Higgins & Company
Designer: Goettsch Partners
Size: 2.3 acres

300 East Randolph is a two-phased, vertically expanded office tower located at the north end of Grant Park in Chicago. The 57-story development sits prominently on a 2.3-acre site overlooking Michigan Avenue, Millennium Park and Lake Michigan in the city’s East Loop district. The building primarily serves as the headquarters for Health Care Service Corporation (HCSC) and its Blue Cross and Blue Shield of Illinois division.

In the mid-‘90s, HCSC required a facility that would consolidate operations while providing a plan for long-term growth—without relocating. The design team’s innovative solution is the unprecedented concept of vertical expansion. The building’s 33-story first phase was completed in 1997; more than a decade later in 2010, phase two was completed, adding 24 stories atop the original, fully occupied building. The phase two expansion allows HCSC to grow, as well as add other leading tenants.
