Richard and Dion Neutra, 1972: One of the most significant architectural offerings in the U.S. Neutra was a master at integrating architecture within its natural surroundings with the home sitting atop an expansive, nearly 3 acre, promontory with breathtaking 360 degree views. This estate boasts 4 bedrooms, 5 bathrooms, an incredible outdoor space that features a sparkling swimmer's pool, hot tub and unique designer water features flowing seamlessly through the house. This home is truly an architectural masterpiece.
