Nestled within The Country — Diamond Bar's most prestigious 24-hour guard-gated community — this exquisite residence spans approximately 4,199 square feet and offers five bedrooms and four bathrooms. Thoughtfully designed for modern luxury living, the home showcases an open, light-filled floor plan that radiates warmth, sophistication, and timeless elegance. The gourmet kitchen serves as the heart of the home, featuring top-of-the-line appliances, custom designer cabinetry, and premium fixtures. It opens seamlessly to the expansive family room, where floor-to-ceiling windows frame sweeping hillside views and capture the soft ocean breeze — creating an inviting setting for both everyday living and grand entertaining. Distinctive details elevate the home's refined aesthetic, including smooth-finish interior walls, a newly completed exterior smooth stucco finish, and elegant new Italian tile flooring that complements the residence's contemporary design. The remodeled kitchen is equipped with high-end appliances, custom cabinetry, and designer plumbing fixtures, combining functionality with style.

Two spacious decks extend gracefully from the main residence, blending indoor and outdoor living with effortless sophistication. From the upper deck, enjoy breathtaking panoramic views — on a clear day, you can even see Catalina Island and watch sailboats gliding across the ocean horizon. The property also includes an almost-approved ADU plan, offering an exceptional opportunity to expand living space or create a private guest suite. Don't miss this rare opportunity to own one of Diamond Bar's most captivating hillside estates — a perfect balance of luxury, serenity, and natural beauty.
