8 Oak Arbor Rd

A rare architectural masterpiece by Henry Hill, a founder of the Second Bay Tradition. Privately sited on one of Orinda’s most coveted streets, this landmark estate blends timeless modernist design with nature. Invisible from the road, the home is nestled among majestic oaks and reached by a gated private drive. Enter the home under a sloping beamed ceiling. The formal dining room seats 8-10, beneath skylights. Adjacent is the living room warmed by a grand fireplace. The open-concept interior is characteristic of the architectural style, as the kitchen (under skylights) leads gently down brick steps to the family room. The kitchen is impeccably appointed, with elite appliances, exquisite marble counters, and a matching island over 80 sq ft. Oversized windows draw in cheery morning sun, over the infinity swimming pool, spa, deck, and play area. A spacious office and library/den are found down a brick hallway. Four bedrooms and 3½ bathrooms lie further down. The roughly 350 sq ft principal bedroom is particularly distinctive. A fifth bedroom – perfect as a guest room/in-law suite – is situated at the other end of the home. Parking is easy in the 3-car garage and parking court. This home is an exceptional retreat – minutes to town, yet secluded – just as its architect intended.
