Designed in 1915, Frank Lloyd Wright's Allen House is considered the last of the Prairie houses, which Frank Lloyd Wright considered "among my best." Restored back to 1918, the house exemplifies Frank Lloyd Wright's philosophy of living in harmony with nature. The house was pivotal in the movement to the Usonian designs of 1935. Interior furnishings manufactured by Niedecken Walbridge represent the last of twelve collaborations. Considered by many visitors "the house of choice to live in!"
