Rare opportunity to own a fully permitted, expanded San Mateo Highlands home on the market for the first time in over 60 years. This expansive 2,460 sq ft 6BR/3BA home sits on a 9,800 sq ft lot and backs to the canyon, offering the privacy and serenity that makes this neighborhood so coveted. Soaring 10-foot tongue-and-groove ceilings and walls of glass in the main living areas, clean lines, and indoor-outdoor flow define the legacy here, while a thoughtfully expanded footprint gives multigenerational families genuine room to breathe. A newer roof and sewer line (both replaced in 2021) anchor a home that is otherwise primed for a full, thoughtful renovation. The home is ready for a family with vision someone who recognizes that the bones, the setting, the location, and the history cannot be replicated, and that the opportunity to put their own mark on a true mid-century original rarely comes twice. Moments from the community Recreation Center, Highlands School, and convenient access to Highways 280, 92, and 101.
