Prairie School is a late 19th and early 20th-century architectural style, most common in the Midwestern United States. The style is usually marked by horizontal lines, flat or hipped roofs with broad overhanging eaves, windows grouped in horizontal bands, integration with the landscape, solid construction, craftsmanship, and discipline in the use of ornament. Horizontal lines were thought to evoke and relate to the wide, flat, treeless expanses of America's native prairie landscape.
