Frank lloyd wright's style of architecture was Unique,specially because they were long and norrow,this Style was Callered the Pririe . 3 of his most famous designs were fallingwater,Robie House, and Taliesin.I think he stayed famous was because his design were not out of style,and everything was so planed,well thought and special to him and most of the people who saw them or owned them.I dont think any of his work was bad,I really like his deigns.
