GM's headquarters were located in Flint until the mid-1920s, when they were moved to Detroit. Its building, originally to be called the Durant Building, was designed and began construction in 1919 when Durant was president, was completed in 1923. Alfred P. Sloan became president that year, and the building was officially dedicated as the General Motors Building in 1929. GM maintained this headquarters location, now called Cadillac Place, until it purchased the Renaissance Center in 1996. The Buick Division headquarters remained in Flint until 1998 when it was relocated to the Renaissance Center.
