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.

In architecture, an overhang is a protruding structure that may provide protection for lower levels. Overhangs on two sides of Pennsylvania Dutch barns protect doors, windows, and other lower-level structures. Overhangs on all four sides of barns and larger, older farmhouses are common in Swiss architecture. An overhanging eave is the edge of a roof, protruding outwards from the side of the building, generally to provide weather protection.
