151 North Franklin

151 North Franklin (officially named CNA Center) is a skyscraper located at 151 North Franklin Street Floor 9 in the Chicago Loop. Completed in 2018 and standing at 568 feet (173 meters) tall with 35 floors at the northeast corner of West Randolph Street and North Franklin Street, the building is the current corporate headquarters of namesake tenant CNA Insurance, which has been headquartered in the Loop since 1900. It also hosts large office spaces for Facebook and the law firm Hinshaw & Culbertson.

The vision for the building first became public in 2013 when renderings were availed for a 30-story building from developer John Buck designed by John Ronan, with AAI Associates, Inc. as architect of record. In November 2013, Buck announced $145 million of equity financing for a 36-story building with 825,000 square feet (76,645 m2) of office space. In February 2015, law firm Freeborn & Peters (Chicago's 22nd largest) signed a 15-year 5-floor letter of intent. That May, law firm Hinshaw & Culbertson (Chicago's 14th largest) signed a lease in the building. In August 2015, Freeborn & Peters accepted an offer to remain at 311 South Wacker Drive, but Buck went ahead with filing for demolition permits for the Walgreens at that location. In December 2015, CNA Insurance decided to relocate its headquarters from the 44-story CNA Center at 333 South Wabash that it had owned since its debut in 1972 to the new CNA Center building. The plan included selling the old building to Buck for $108 million, temporarily leasing space in that building until moving into the newly leased space with signage and naming rights. By that time the Walgreens on the site had been demolished and construction was expected to commence soon. Northern Trust would sign to consolidate many of its offices into the old CNA Center, which was to be renamed by Northern Trust. In June 2018, 151 North Franklin became the new corporate headquarters for CNA Insurance, which has been headquartered in the Chicago Loop since 1900. Prior Loop headquarters included following locations: Metropolitan Tower (Continental Center I from 1943–1962 at 310 South Michigan Avenue), 55 East Jackson Boulevard (Continental Center
