Agent Remarks

Striking panoramic-view residence set within the prestigious "Diamond Ridge Estates "community of Diamond Bar and located in the award-winning Walnut Valley Unified School District. Designed for both refined living and grand-scale entertaining, this exceptional 4-bedroom, 3.5-bath home makes an immediate statement with an elegant double-door entry opening to a dramatic grand foyer, soaring ceilings, and an abundance of natural light. The formal living room offers an impressive sense of volume, while the cathedral-ceiling dining room creates a sophisticated setting for unforgettable gatherings. The thoughtfully designed floor plan includes a desirable main-level en-suite bedroom with a private bath, ideal for guests, extended family, or multigenerational living. At the heart of the home, the open-concept kitchen features a generous center island and flows seamlessly into the spacious family room with high ceilings and a cozy fireplace, creating an inviting setting for everyday living and entertaining. Upstairs, the expansive primary suite offers two spacious walk-in closets and a well-appointed bath with a separate shower and soaking tub. Additional highlights include an individual laundry room with ample built-in cabinetry, fresh interior and exterior paint, new waterproof wood flooring throughout much of the renovated interior, and custom tile flooring at the entry and kitchen. Outdoors, the property continues to impress with a generously sized front yard, an expansive private driveway offering ample parking, and a charming sitting area beyond the low decorative iron gate—perfect for relaxing and enjoying the peaceful surroundings. The spacious backyard with patio provides another wonderful setting for entertaining while taking in spectacular canyon and mountain views. Elegant slate fountain with a serene pond and cascading waterfall, creating a sophisticated outdoor focal point. Conveniently located near the 60 and 57 Freeways, this distinctive Diamond Ridge home offers an exceptional combination of location, lifestyle, flexibility, and breathtaking scenery.
