Tucked away on a quiet cul-de-sac, well removed from road noise, this exceptional Happy Valley property provides rare tranquility on a private 3/4-acre setting. Expansive, curated gardens and sitting areas—featured in Better Homes and Gardens, HGTV, Sunset Magazine, and multiple garden tours—create a sanctuary framed by mature oaks, redwoods, and a year-round creek. A thoughtfully designed layout separates living and entertaining spaces from the private bedroom wing. A hallway leads past an enclosed garden courtyard, a serene outdoor escape. A signature architectural feature is the swimming pool, which begins inside the dining room and extends beneath a walkway into the backyard. The private wing includes 4 bedrooms, with potential for a spacious 5th-bedroom conversion overlooking 2 garden courtyards. The principal suite enjoys exceptional garden and creek views. A detached ADU/studio provides an ideal space for guests, a home office, or gym. A circular driveway and 3-car garage provide ample parking. It’s just walking distance to Briones Regional Park trailhead. Downtown Lafayette, Highway 24, BART, and top-rated schools are nearby. This is a rare opportunity to own one of Happy Valley’s most distinctive properties.

Happy Valley, located between downtown Lafayette and the Briones Regional Park foothills, is a residential and semi-rural Lafayette neighborhood with rolling hills and equestrian properties. The neighborhood reads as a patchwork of ranch-style homes, gated lanes, and long driveways framed by oaks and open pasture. The character concentrates around the Happy Valley Road and Pleasant Hill Road junction, where morning traffic, cyclists, and school runs set a steady tempo. A short drive away, the Lafayette Reservoir loop and the Lafayette Library and Learning Center function as everyday anchors for walks, reading, and community programs. Weekends often point toward the Lafayette Farmers Market for local produce and a town-square feel. The landscape shifts quickly from manicured lots to trailheads and ridgelines, keeping the mood quiet and outdoors-oriented.
