Usonia was a word used by American architect Frank Lloyd Wright to refer to his vision for the landscape of the United States, including the planning of cities and the architecture of buildings. Wright proposed the use of the adjective Usonian in place of American to describe the particular New World character of the American landscape as distinct and free of previous architectural conventions.
