Welcome to Your Private Hilltop Sanctuary.
Nestled within Diamond Bar’s highly prestigious, 24-hour guard-gated community of The Country Estates, this fully reimagined masterpiece offers a rare blend of classic curb appeal and breathtaking, ultra-modern design. Shielded by mature landscaping, this estate invites you to experience a lifestyle defined by uncompromising luxury, sweeping valley sunsets, and sparkling city-light views.
Step through the illuminated entryway into a sun-drenched, open-concept floor plan beautifully anchored by custom vertical wood-slat architectural paneling, wide-plank oak-toned flooring, and brilliant crystal chandeliers. The gourmet chef’s kitchen is an entertainer’s dream, featuring a massive quartz waterfall island and a farmhouse sink, flowing seamlessly into a formal dining space warmed by a marble-clad fireplace. You can effortlessly host guests in the formal living room with its built-in beverage center, or find your daily peace in the dedicated, window-lined Zen lounge. Ascending the striking glass-framed staircase reveals a sprawling upper-level entertainment loft alongside a dedicated billiard room with private deck access. For the modern professional, a refined executive office offers a quiet workspace complete with custom solid-wood built-ins and glass-paned French doors.
The primary suite is a true resort-style retreat designed to capture unobstructed hilltop horizon views. Its spa-caliber en-suite rivals five-star hotels, appointed with a deep freestanding soaking tub, a frameless glass rainfall shower, brushed gold fixtures, and a massive custom walk-in closet. Generously sized secondary bedrooms offer VIP treatment with bespoke board-and-batten woodwork, while the pristine guest baths feature designer finishes, and high-tech smart bidets.
The perfection extends to a fully finished, expansive garage featuring pristine epoxy flooring, custom dark-oak cabinetry, and an integrated luxury laundry center. Step outside to the modern, cable-railed view decks for al fresco dining under the stars, seamlessly expanding your living space into the California golden hour.
Residents of The Country Estates including a massive indoor sports complex, pristine clay and hard tennis courts, pickleball, a community pool, and miles of scenic equestrian trails. Zoned for the award-winning Walnut Valley Unified School District, this estate is more than just a stunning residence—it is a legacy property.
