Falling Water by Frank Lloyd Wright. Fallingwater or Kaufmann Residence is a house designed by architect Frank Lloyd Wright in 1935 in rural southwestern Pennsylvania, 43 miles southeast of Pittsburgh.
I absolutely love this. Reminds me of an adobe bubble house I saw in an article many years ago. Richard Olsen's Book Handmade Houses Showcases Beautiful and Unusual Homes : Architectural Digest. Probably for my future little house in Europe.
