The Charles Stewart Mott Foundation Building is a 16-story office high-rise building in downtown Flint, Michigan. It is the tallest building in the city. Designed by Wirt C. Rowland in 1928 and opened in 1930, it was built as the Union Industrial Bank Building to serve as the headquarters for Union Industrial Bank. Rowland was considered innovative for his use of two materials in the building's construction: Nirosta for decorative purposes in the public spaces and aluminum for its storefronts and window frames.

Wirt Clinton Rowland was an American architect best known for his work in Detroit, Michigan.
