Perched high on a private hillside cul-de-sac, this custom 4,000+ sq ft estate offers sweeping 180-degree views of the Riverside Valley, sparkling city lights, and surrounding mountains. Built in 2005 and hitting the market for the first time, this Spanish-inspired home pairs timeless architecture with incredible potential — a rare opportunity to reimagine a hilltop retreat with some TLC and personal touches. A grand double-door entry opens to imported Spanish tile and a dramatic spiral staircase that sets an unforgettable tone. The open gourmet kitchen features granite countertops, custom cabinetry, dual wall ovens, a 5-burner gas range with stainless vent hood, and a spacious walk-in pantry. A bright breakfast nook opens to the backyard, while the formal dining room and adjoining family room — complete with gas fireplace and wet bar — create an inviting space for both entertaining and everyday living. The main floor also includes a private office with glass French doors, a guest bedroom with full bath and dual sinks, a powder room, laundry room, and an additional bath with pool access. Upstairs, the owner’s suite impresses with a dual-sided fireplace, wet bar, and two sets of French doors leading to the expansive wrap-around deck with panoramic views. The ensuite bath features dual vanities, frameless glass shower with dual shower heads, soaking jetted tub, and a generous walk-in closet. A loft and two additional bedrooms share a Jack-and-Jill bath, each opening to the deck as well. Set on nearly 4 acres, the property includes a sparkling pool and spa, shaded pergola, fruit trees, and space for a future casita or guest house. With a 4-car garage, unmatched privacy, and proximity to top-rated schools, shopping, and dining, this is an extraordinary opportunity to bring new life to one of Riverside’s most distinctive view properties.
