Frank Lloyd Wright’s “Prairie Style” became the basis of American residential design in 20th-century America. He designed numerous iconic buildings in an organic style developed to be appropriately Midwestern. In 1893, Frank Lloyd Wright founded his architectural practice in Oak Park, a quiet, semi-rural village on the Western edges of Chicago. It was at his Oak Park Studio during the first decade of the twentieth century that Wright pioneered a bold new approach to domestic architecture, the Prairie style. A masterful architectural designer, Wright developed a unique vocabulary of space, form, and pattern that represented a dramatic shift in design from the traditional houses of the day. Characterized by dramatic horizontal lines and masses, the Prairie buildings that emerged in the first decade of the twentieth century evoke the expansive Midwestern landscape.
