900 North Michigan’s postmodern facade and four corner lanterns make it an iconic presence on the Chicago skyline. Built in 1988 to designs by Kohn Pederson Fox, the building’s 2.7 million square feet contain retail, office, hotel and private residences. A recent renovation created Aster Hall, a new food hall operated by Hogsalt Hospitality, and added a new entry portal – designed to blend seamlessly with the building's rich material palette of limestone and green-tinted glass.
