built in California with a Mayan and Japanese influence. Though some claimed that Wright had peaked in 1910, with the Prairie houses, others claimed that in 1924 Wright's development was only just beginning. Wright's last style, Usonian, was caused by a shift in society in the 1930's. Wright used down scaling to bring the house to a more appropriate human level and reflect the informal and comfortable lives of the average American family.

It seems to sprout form its surroundings almost like a plant.FallingwaterWright continued to produce work into the forties and fifties including houses, churches, theaters, and stores.
