Richard Neutra's Bailey Case Study House #20 is the timeless centerpiece of the Sam Simon Estate. The Estate is comprised of the Bailey House and a LEED Certified Gold contemporary "main house," thoughtfully sited on spectacular, park-like grounds. Only 24 houses were actually constructed as part of the Case Study House program; 21 remain standing, only one designed by Neutra was built. Simon engaged master architects Marmol Radziner to preserve and renovate the Bailey to achieve a Santa Monica Conservancy Renovation Award. The Simon House, expertly crafted with the utmost of precision, represents the forefront of sustainable living today with its energy conservation technology and use of recycled, toxin free materials. The high volume living room is the focus of a design that also features a spectacular theater/bar/game room that connects to a stone deck with a cascading infinity-edge pool, beautiful views of the Bailey House and the magnificent, private grounds.

ZIP averages use publicly displayable closed sales from our licensed MLS feed, matched to the same ZIP and exact property type. Months with fewer than 3 sales are omitted; the current month is incomplete. Lines connect available monthly observations across gaps and do not represent measured prices in missing months. These averages are not adjusted for size, condition, or location within the ZIP, and are not an appraisal. Feed coverage may not include every sale. All available shows the available home and ZIP history, with mortgage rates over the same dates.
Mortgage benchmark: Freddie Mac Primary Mortgage Market Survey®. © Freddie Mac. Weekly national 30-year fixed rates, not APRs or a loan quote. Actual terms vary. Methodology changed in November 2022. The chart does not establish that interest-rate changes caused a home’s price changes.
Lines connect recorded asking and sale prices. They are visual guides, not estimates of the home’s value between those dates.
No earlier records were returned by our current sources. This does not mean the home has never sold.
