The Carbide & Carbon Building is a 37-story, 503 feet (153 m) landmark Art Deco skyscraper built in 1929, located on Michigan Avenue in Chicago. The building was designed by the Burnham Brothers as the regional office of Union Carbide and Carbon Co.. It was transformed into the Hard Rock Hotel Chicago from 2001-2004. The $106 million conversion was directed by Lucien Lagrange & Associates. The current hotel capacity is 383 guest rooms and 13 suites. The Hard Rock Hotel closed on December 1, 2017, and reopened in 2018 as the St. Jane Chicago Hotel, named for Nobel Peace Prize-winner and noted Chicagoan, social activist Jane Addams. (wikipedia.org)
