This style was one of Frank Lloyd Wright’s major contributions to architecture. It derives its name from his intent to echo the flat midwest prairies. Hence, buildings are strongly horizontal with low, protecting roofs. The modern movement, of which Wright was a leading proponent, sought to use materials, methods and architectural elements in new ways.
FORM: simple rectangles, L & T shaped plans; 1—2 stories; often with brick, stucco, and/or wood in horizontal bands.
ROOF: hip or gable, with broad overhangs; sometimes gable or shed dormers.
WINDOWS: casements, often with decorative muntin patterns.
TRIM: wood bandings, or broad flat exterior casings, head moldings & sill aprons; all very horizontal.
