Architectural legacy meets California tranquility in this AIA-recognized residence by acclaimed architect Donald Olsen. Built in 1967 for his close friends the Ruth Family, this mid-century modern architecture includes a friendly floorplan with 4 bedrooms and 3 full baths, showcasing Olsen’s signature integration of geometry, light, and nature. Built on a secluded knoll-lot of approximately 0.38 acres around a magnificent heritage coastal live oak and perched above a serene creek, the home captures the essence of Berkeley’s architectural and natural beauty. Thoughtfully preserved and meticulously improved, the property features walls of glass, original hardwood floors, seismic upgrades, landscape renovations by RDG Landscape Architects including a full native-plant and creek restoration, illuminated walkways, and the exterior patio is embossed with San Francisco cobblestones. A custom O2 Treehouse floats among the oaks, adding playfulness to the refined design. Set in the prestigious Claremont neighborhood, this property offers ADU or multi-generational potential and effortless access to the Claremont Club & Spa, Rockridge BART, and freeway access.

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.
