The American Foursquare or American Four Square is an American house vernacular under the Arts and Crafts style popular from the mid-1890s to the late 1930s. A reaction to the ornate and mass-produced elements of the Victorian and other Revival styles popular throughout the last half of the 19th century, the American Foursquare was plain, often incorporating handcrafted "honest" woodwork. This architectural vernacular incorporates elements of the Prairie School and the Craftsman styles. It is also sometimes called Transitional Period.

American Craftsman is an American domestic architectural style, inspired by the Arts and Crafts movement, which included interior design, landscape design, applied arts, and decorative arts, beginning in the last years of the 19th century. Its immediate ancestors in American architecture are the Shingle style, which began the move away from Victorian ornamentation toward simpler forms, and the Prairie style of Frank Lloyd Wright.
