The Stahl house was built client Bucky Stahl who was enamored with his lot's incredible views of Los Angeles. He was determined to have a wall-less wing on that side and (like Leonard Malin with the Chemosphere) was told that it was impossible. The only architect up for the challenge was Pierre Koenig. Today, the Stahl house is privately owned, occasionally open to the public. If you're in LA, you should definitely check it out.
