Property Description

Tucked away from the main road in a quiet, secluded setting, this updated Diamond Bar home feels like your own private retreat. Situated on an approximately 13,878 sq. ft. lot, this 4-bedroom, 2-bath home offers 1,859 sq. ft. of living space with the privacy, views, and outdoor space that are hard to find. Inside, you’ll find an updated kitchen with modern cabinetry and countertops, updated flooring and lighting, remodeled bathrooms, and a bright living space centered around a stone fireplace. One of the home’s standout features is a full bedroom and bathroom downstairs, privately positioned from the remaining bedrooms, ideal for parents, in-laws, guests, or multigenerational living. Upstairs, the primary bedroom captures beautiful hillside, neighborhood, city-light, and sunset views, along with a large closet and direct access to the upstairs bathroom. Step outside and the home takes on a true resort like feel. The private backyard features a pool and spa, mature landscaping, and an extended patio with plenty of room to relax, entertain, and enjoy Southern California living. Out front, new concrete and fresh grass complement a massive driveway and 2-car garage, providing plenty of parking. Despite its secluded setting, the home is conveniently positioned between the 57 and 60 freeways, keeping everyday amenities and surrounding communities within easy reach. Private, updated, and designed for both entertaining and family living, this is a side of Diamond Bar you have to experience in person.
