Discover the pinnacle of hillside luxury in this fully reimagined 4-bedroom, 4-bath estate—3,669 sq ft of sleek, modern design set atop a private 1.78-acre knoll in the guard-gated Diamond Bar Country Estates. From the moment you arrive, you’re greeted by sweeping canyon-to-city-light panoramas that flow through walls of window's glass and expansive ceilings, bathing every room in warm, natural light.
At the heart of the home, the chef’s kitchen shines with a dramatic waterfall-edge quartz island, premium appliances, custom European-style cabinetry, and polished hardware—perfect for both everyday meals and grand entertaining. Each spa-inspired bathroom is a sanctuary, boasting floating vanities, floor-to-ceiling tile, frameless rain-head showers, deep soaking tubs, and sleek bidet-equipped toilets.
The versatile three-story floor plan features a main-level guest suite with private deck access, an upstairs loft/media room framed by glass railings, and a tucked-away fitness nook overlooking mature oaks. Step outside to an entertainer’s dream: multiple wraparound decks and covered verandas, a built-in barbecue with prep station, glowing fire pit, and terraced gardens—all designed for sunset cocktails, morning coffee, or starlit gatherings.
Enjoy the perfect blend of tranquility and convenience—just minutes from top-rated schools, scenic hiking and biking trails, premier shopping, and fine dining. This is not just a home; it’s a lifestyle destination with the most breathtaking views in Diamond Bar.
