Prairie Style or Prairie School - Architecture created primarily in the midwestern U.S., beginning in Chicago c.1900 with Louis Sullivan (American, 1856-1924) and Frank Lloyd Wright (American, 1867-1959). Exploring new ways of relating buildings to the land, these architects employed undecorated natural materials, and developed new concepts of interior space.

Wright said: "We of the Middle West are living on the Prairie. The prairie has a beauty of its own and we should recognize and accentuate this natural beauty, its quiet level. Hence, gently sloping roofs, low proportions, quiet sky lines, suppressed heavy-set chimneys and sheltering overhangs, low terraces and out-reaching walls sequestering private gardens."

An example:

Frank Lloyd Wright (American, 1867-1959), Frederick C. Robie House, Chicago, 1906-09, Chicago, IL, a model construction of wood, cardboard, and paint, 9 1/8 x 49 5/16 x 21 3/8 inches (23.2 x 125.3 x 54.3 cm), Museum of Modern Art, NY. The exterior of this residence presents long overhangs on low-pitched roofs and horizontally raked brick joints. More on the Robie House.
