Tucked away in the loved Happy Valley Glen neighborhood, this expanded single-story traditional is filled with natural light and high-end finishes. Situated on nearly an acre of land, that extends up the hillside, the parcel affords a large level area, rare depth and a tremendous amount of privacy! In 1996 and 1997 the home underwent a major renovation (down the studs) which included the addition of a bonus room (potential 5th Bedroom) and full bath. In 2018, the home had a full kitchen and bath remodel as well. The result is a stunning home that checks all of the boxes for today’s live, work and retreat lifestyle.The resort-like backyard features a pool, putting green, sport court, fire table, multiple patios, outdoor kitchen, vegetable garden, and with views of the Briones hills for tranquil indoor/outdoor living and entertaining. This home is located minutes from Hwy. 24, BART, Oakwood Athletic Club, Lafayette Reservoir, Briones Regional Park, downtown and top-rated schools.
