8 Oak Arbor Road

A rare architectural masterpiece by Henry Hill, a founder of the Second Bay Tradition. Privately set on one of Orinda's most coveted streets, this landmark estate embodies timeless modernism in harmony with nature. Hidden from view and approached by a gated drive beneath heritage oaks, the home unfolds with quiet grandeur. Enter beneath a sloping beamed ceiling into a sunlit interior that blurs the line between indoors and out. The formal dining room, illuminated by skylights, comfortably seats eight to ten. The adjacent living room centers around a striking fireplace, while the open-concept kitchen flows seamlessly to the family room down gentle brick steps. The chef's kitchen features marble counters, a matching 80-square-foot island, skylights, and premium appliances. Walls of glass frame morning light over the infinity-edge pool, spa, deck, and play area. A spacious office and a library/den line a brick hallway, leading to four bedrooms and three-and-a-half baths, including a distinctive 350-square-foot primary suite. A fifth bedroom--ideal for guests or extended family--sits privately at the opposite end of the home. With a three-car garage and ample parking court, this secluded retreat offers architectural pedigree, serenity, and proximity to downtown Orinda.
