Framed by an oak-studded landscape in Lafayette’s coveted Happy Valley neighborhood, this exceptional 2020-built residence pairs striking contemporary architecture with extraordinary craftsmanship, designer detail, and modern luxury. Encompassing 4,114± square feet, the home offers four bedrooms, three-and-a-half baths, a dedicated office, bonus room, and three-car garage. From the moment you enter, the quality is unmistakable. Soaring ceilings, exposed wood beams, walls of glass, wide-plank flooring, dramatic lighting, and richly layered natural materials create interiors that feel warm and completely custom. The spectacular great room is anchored by a sleek linear fireplace and floor-to-ceiling wood feature wall, while oversized glass doors frame the surrounding landscape and open the home to the outdoors. Integrated smart-home features include automated draperies and lighting. At the heart of the home, the chef’s kitchen features rich wood cabinetry, an oversized island, double ovens, generous prep space, statement lighting, and a substantial walk-in pantry. The adjoining dining area connects effortlessly to the kitchen, great room, and outdoor spaces. Designer details continue throughout. The office provides an inspiring work-from-home setting, while the bonus room, currently outfitted as a gym, opens to a private deck with wooded views. The primary suite is a serene retreat with direct outdoor access, a massive walk-in closet, and a spa-like bath illuminated by a skylight and featuring an expansive dual vanity and oversized glass-enclosed shower. Outside, the property unfolds across more than half an acre of beautifully landscaped, terraced grounds. Expansive patios offer multiple areas for dining and lounging alongside a built-in grill, sculptural fountain, lawn, layered plantings, and intimate hillside terraces. A separate laundry room adds everyday function. Tucked into an accessible wooded hillside yet remarkably close to downtown Lafayette, BART, commute routes, and highly rated schools, the location offers the best of both worlds: privacy and natural beauty without sacrificing convenience. Nearly new, impeccably designed, and finished to a level that must be experienced in person, this is a rare Happy Valley offering.
