A group of young architects, including Frank Lloyd Wright, established the Prairie style in Chicago around 1900. This style honors the flat, extended terrain of the Midwest. Their emphasis on the horizontal, as opposed to the vertical, is their most distinguishing feature. They have flat or shallowly hipped roofs, rows of windows, overhanging eaves, and horizontal bands of stone, wood, or brick. Occasionally, thin Roman bricks accentuate the appearance, and cantilevers frequently prolong the horizontal line without vertical support. Even the undesirable verticals of downspouts are deleted or placed with care.
