Perched to capture breathtaking panoramic mountain, valley, and sparkling city-light views, 821 Guanajuato Drive is a stunning Spanish-style estate located at the end of a quiet cul-de-sac in the prestigious Claraboya neighborhood of north Claremont. Set on an expansive 1.29-acre lot - one of the largest in the community - this rare property combines timeless architecture, exceptional privacy, and spectacular view-oriented living. Double leaded-glass entry doors open to a dramatic foyer with soaring ceilings and an open, light-filled floor plan designed to maximize the home's extraordinary views. Formal living and dining rooms are framed by expansive windows that capture sweeping vistas, while rich architectural details - including wood-beamed ceilings, decorative niches, and multiple fireplaces - add warmth and elegance throughout. The spacious great room features skylights and French doors that create a seamless indoor-outdoor flow, drawing your attention to the stunning surrounding scenery. At the heart of the home, the remodeled kitchen showcases an oversized quartz island, premium Thermador appliances, and a breakfast nook and family area perfectly positioned to enjoy the spectacular mountain and city views. The private primary suite opens to a tranquil courtyard with a relaxing jacuzzi, offering a peaceful retreat surrounded by serene vistas. Outdoors, the expansive grounds are designed for both entertaining and everyday enjoyment, featuring multiple view patios, a built-in barbecue, beautifully landscaped front and back yards, mature fruit trees, and edible gardens that create an inviting garden-to-table lifestyle. A large flat grassy area offers ample space for recreation, gatherings, or future expansion, with potential for a guest house, casita, or private retreat - all while enjoying the property's remarkable panoramic setting. Additional highlights include two SolarCity solar systems with a fixed Tesla energy rate of approximately $0.15/kWh, a full PEX repipe completed approximately eight years ago (with copper plumbing in the kitchen), automated sprinklers, two storage sheds, a dedicated dog run, and a wide double side gate. This exceptional Claraboya estate offers a rare combination of privacy, expansive usable land, timeless Spanish charm, and truly unforgettable panoramic views in one of Claremont's most coveted neighborhoods.
