About this home

Luxury, security, and sophistication define this magnificent mountain-side estate nestled in Diamond Bar’s premier 24-hour guard-gated community. Impeccably customized for personal primary living with over 300K in high-end premium upgrades, this rare move-in ready masterpiece features 5 bedrooms, 4.5 bathrooms, and a 3-car garage across 4,212 square feet of refined living space. As you enter, a grand foyer with dramatic 20-foot double-height ceilings sets an majestic tone, complemented by 9-foot ceilings throughout the house. The versatile floor plan offers a rare dual-primary layout, featuring a massive secondary primary suite on the first floor alongside two spacious living areas, while the upper level provides two additional lofts. The gourmet chef’s kitchen is a culinary dream, equipped with custom slim shaker cabinetry, top-of-the-line Sub-Zero and Wolf appliances, and a large separate walk-in pantry that functions perfectly as a secondary wok kitchen. Uncompromising craftsmanship is evident throughout, from the fully integrated smart home system and multi-layer White Oak engineered hardwood flooring to the ultra-premium imported Italian porcelain tiles in the newly renovated kitchen and all bathrooms. Complete peace of mind is ensured by brand-new plumbing and a central water softener system. Situated halfway up the mountain on a tranquil cul-de-sac, the home backs directly into the hillside for ultimate privacy and serene views, while offering unparalleled convenience to local amenities.
