About This Home

As of October 2025

A rare find! Views, space, and potential in one of Castro Valley’s most desirable settings. Never before on the market. Mid-century modern home with sweeping Bay views, huge deck, a spacious primary suite, loads of driveway parking, and a 2-car garage, with interior access. All sitting on a huge 18,000 sq ft cul-de-sac lot. Gleaming wood floors, bonus 787 sq ft workshop space offers potential for an office, a second suite, or ADU and sewer lateral compliance. Loved by one family since it was built—ready for its next chapter! Close to award-winning schools, amazing parks, and Castro Valley conveniences.
