About This Home

21 Cobblestone Lane

21 Cobblestone Lane is one of the original 1930s summer residences built at the end of Graceland Avenue, set on an expansive lot of more than half an acre, an exceptionally rare offering in San Carlos. This well-maintained property presents a unique opportunity to build your dream home, thoughtfully remodel the existing residence, or explore potential subdivision opportunities (buyer to verify with the City). The home features three spacious bedrooms and three bathrooms, a generous living room, a separate den, an updated kitchen, and two distinct dining areas ideal for both everyday living and entertaining. A detached two-car garage and oversized driveways provide ample parking for guests. With abundant space, privacy, and endless potential, this is a truly rare opportunity in The City of Good Living.
