In the early 20th century, with the major development of Detroit's Washington Boulevard launched by the Book brothers, Louis Kamper was called to redesign the street wall of the area. As a result, the boulevard is now lined with several Kamper-designed buildings: the Book Building (1916), the Washington Boulevard Building (1922–23), the Book-Cadillac Hotel (1924), the Book Tower (1926), and the Industrial Building (1928). Other downtown works include the Cadillac Square Building (1918), demolished in 1978, and the Water Board Building (1928), one of his finest skyscrapers.
His residential architectural projects include the Châteauesque style Col. Frank J. Hecker House in Detroit, and the Italian Renaissance Revival style Murray Sales House (1917) in Grosse Pointe, Michigan.[note 1]
Louis Kamper styled the four architectural sculptures above the Michigan Avenue entrance to the Book-Cadillac Hotel which are, from left to right: Anthony Wayne, Antoine Cadillac, Chief Pontiac, and Robert Navarre.
