The Frank Lloyd Wright Foundation lists 1950 as the design year, but other sources say Wright delivered plans in 1951. The core living area was finished in 1957 and two more bedrooms in 1959, with Berger not only doing the construction but also building the furniture himself. When Berger fell ill in 1969, his wife hired a professional carpenter to complete the remaining finish work. You can read the story of its construction here.
The Berger House was built using a "desert masonry" technique with 14-inch-thick walls, similar to Taliesin West in Phoenix and the Pilgrim Congregational Church in Redding. The basic geometry is a diamond shape, with corners of 120 or 60 degrees. You can see a few interior views of it here.
