Welcome to this remodeled split-level estate in The Country, the 24-hour guard-gated Diamond Bar Country Estates. The main level opens to vaulted beamed ceilings, marble flooring, and a floor-to-ceiling marble fireplace, flowing into a skylit open-concept kitchen with custom white cabinetry, black granite countertops, stainless steel appliances, and a built-in wet bar with seating. A private bedroom wing offers a primary suite with private balcony, walk-in closet, and spa-style ensuite featuring a jetted soaking tub, plus three additional bedrooms and a full bath. The lower level adds a flexible lounge and family room with its own bar, ideal for entertaining or multi-generational living. Covered decks with brand-new railings span all three levels, framing panoramic views over a pool-sized backyard with room to build your own pool. Extensively upgraded with new HVAC, luxury vinyl plank flooring, fresh interior paint, designer lighting, plantation shutters, and a finished three-car garage with epoxy floors. Located within award winning top ranking Walnut Valley School District and minutes to the 57 and 60 freeways, Diamond Bar Golf Course, and The Shoppes at Chino Hills, with an easy commute to LA, Orange County, and the Inland Empire.
