The DuPont Building, occupying the entire block bound by 10th, 11th, Orange, and Market streets, was one of the first high-rises in Wilmington, Delaware, United States. It looks out over Rodney Square. The building was built in phases, with the original building constructed in 1908 fronting Rodney Square. At the time, the building housed the offices of DuPont. In 1913, the building was expanded into a "U" by adding wings along 10th and 11th streets, the DuPont Playhouse was added, and a portion of the original 1908 section was converted into the Hotel du Pont.[2] (Hotel du Pont is a member of Historic Hotels of America, the official program of the National Trust for Historic Preservation.[3]) The final addition to the building occurred in 1923 when the Orange Street addition was added along with an additional two floors, bringing the floor count to 13 and the height to 124 ft.
Until early 2015, the building housed DuPont's headquarters. In December 2014, DuPont announced that it would move and consolidate its corporate headquarters at its nearby Chestnut Run Plaza site and that The Chemours Company, which spun off from DuPont in 2015, would move into the DuPont Building.[4]
