A rare architectural retreat, designed by a renowned Japanese architect. Set on nearly 1.5 acres above the fog, this 5BR/4.5BA estate offers striking views of Briones open space and the reservoir. High ceilings, gracious rooms, and walls of glass create a luminous, open feel, seamlessly blending indoor and outdoor living. At its heart, an interior courtyard with a koi pond fosters tranquility, while a meditation/tatami room offers space for reflection, movement, or a home gym. The wrap-around deck extends the living experience outdoors, leading to the pool, jacuzzi, and gazebo—a sanctuary for relaxation or entertaining. A spacious recreation room, opening to the pool, provides a flexible space for gatherings, creative pursuits, or fitness. The multi-level primary suite is a peaceful escape with a spa-like bath and soaking tub. A second suite anchors the same wing, while three more en suite bedrooms—each with deck access—offer privacy and sweeping views. Two dedicated home offices provide an ideal work-from-home setup, designed to inspire focus and creativity. Located minutes from Orinda’s top schools, downtown, and scenic hiking and biking trails, this estate is a perfect blend of serenity, artistry, and livability—with easy access to San Francisco and Marin.
