A private resort in one of Lafayette's most coveted neighborhoods. Tucked into the hills of Happy Valley near Briones Regional Park, this nearly 4,000-sq-ft single-level home offers 5 bedrooms and 5 bathrooms on nearly an acre, minutes from downtown. At the end of a private lane, a newly refinished paver parking court and attached 2-car garage with a generous mudroom welcome you home. Mature trees frame beautifully landscaped grounds with a pool, Bullfrog spa, Sunlighten sauna, terrace, Trex deck, firepit, turf play area and detached writing studio. Multiple rooms open directly outdoors. Four skylights brighten the open-concept kitchen, featuring a 5-by-6-foot stone island with seating for 5, premium appliances and a wine refrigerator. Engineered oak floors connect inviting living spaces, including a living room with Happy Valley views and a fireplace, and a dining room with floor-to-ceiling windows. Four bedrooms share a hallway; the fifth has an en-suite bath and separate garden entrance, ideal for guests or an au pair. The primary bedroom spans nearly 350 sq ft beneath a beamed ceiling, with a gas fireplace, adjoining bath with soaking tub and oversized shower, and a large walk-in closet. Close to Happy Valley Elementary, downtown dining and shopping, Highway 24 and Lafayette and Orinda BART.
