Property Description

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.
