Modern Sanctuary in Lower South Hillsborough. Welcome to 655 Hayne Road, a newly completed modern residence offering privacy and refined California living in one of Hillsboroughs most desirable neighborhoods. Set behind a gated entrance on a mostly flat, usable parcel, the property is thoughtfully designed for seamless indoor-outdoor living. The main residence flows primarily across a single level, with an open-concept layout that connects effortlessly to the grounds and frames serene treetop views. Positioned just off the main living areas, the attached ADU offers a natural extension of the home, well suited for entertaining, guests, or extended stays. With easy access to the pool and outdoor kitchen, it lives as a cabana-style retreat, enhancing the indoor-outdoor lifestyle. A separate lower-level space offers flexibility for a home theater, gym, or game room. The grounds are carefully composed to create a true sense of escape, blending manicured landscaping, open turf areas, and a natural backdrop. Ideally located just moments from South School and with convenient access to Burlingame, San Mateo, and major commute routes. A rare offering that pairs modern design with usable land in a sought-after Hillsborough setting, ideal for refined indoor-outdoor living.
