The American Foursquare was an extremely popular house. Its box-like shape and hipped roof provided ample room at an economical cost. Stylistically, it shares influences from both the Craftsman and Prairie styles. One of its popular aspects with builders was its adaptability. A Palladian window in the dormer could justify advertising the house as "Colonial styling." A shingle and fieldstone porch could qualify its being called "Artistic." A "Prairie Style" house could be claimed by extending eaves, stretching the porch and using stucco on the exterior.
