This is a rare opportunity to put down roots in one of Lafayette’s most coveted neighborhoods. Tucked into the hills of Happy Valley near Briones Regional Park, this nearly 4,000-square-foot single-level home offers remarkable privacy and a sense of retreat, just minutes from downtown Lafayette. Set above Upper Happy Valley Road at the end of a private lane, the property unfolds across nearly an acre of lush, beautifully layered grounds. A newly refinished paver parking court invites residents and guests to the home, while the attached two-car garage leads into a generous mudroom ready for hiking shoes, sports equipment and other gear for outside play. With the privacy and amenities of a personal resort, this five-bedroom, five-bathroom home sits on nearly an acre framed by mature oaks, redwoods, Douglas firs and Japanese maples. Multiple rooms open onto beautifully landscaped grounds, where a swimming pool, Bullfrog spa and Sunlighten sauna create every day a sense of escape. A spacious terrace, Trex deck and firepit create settings for outdoor dining and lounging, while a turf play area and detached writing studio offer room both for exercise and games, and creative pursuits as well. Bathed in natural light from four skylights, the open-concept kitchen is the heart of the home, equally suited to everyday gathering and entertaining. A generous 5’x6’ stone island offers seating for five, complemented by premium appliances and a wine refrigerator. Engineered oak floors flow throughout, connecting the kitchen to a spacious living room with views across Happy Valley and a fireplace for cozy evenings. In the dining room, floor-to-ceiling windows bring the surrounding greenery into view, creating an inviting setting for family meals and celebrations. Four of the five bedrooms lie down a hallway from the kitchen; the fifth, ideal for guests or an au pair, offers an en-suite bathroom and a separate entrance from the garden. The principal suite is particularly noteworthy. The bedroom alone is nearly 350 square feet, under a beamed ceiling, with a gas fireplace. It adjoins a spacious bathroom with a soaking tub and oversized shower with elite fixtures, as well as a huge walk-in closet. Happy Valley Elementary School is just up the street and around the corner. Lafayette’s restaurants and shopping are close at hand, and Upper Happy Valley Road leads quickly to the 24 freeway, providing easy access to Walnut Creek to the east, Oakland and San Francisco to the west, and both the Lafayette and Orinda BART stations.
