Perched on an expansive 12,036 sq.ft. view lot in Walnut’s highly sought-after Timberline Community, this extensively redesigned south-facing residence offers a rare combination of panoramic views, designer finishes, and future potential. Unlike many view homes where the scenery is reserved for the upper level, this exceptional property captures breathtaking mountain and city-light vistas from both floors, creating a truly immersive indoor-outdoor living experience. Offering approximately 2,440 sq.ft. of living space, including a fully permitted sunroom, the home features 4 bedrooms and 3 bathrooms within a thoughtfully designed floor plan that balances comfort, functionality, and elegance. Every detail has been carefully curated, from the stunning modern kitchen with custom cabinetry a nd premium finishes to the beautifully reimagined bathrooms, luxury flooring, updated lighting, and refined designer touches throughout. Sun-filled living spaces flow effortlessly into the versatile sunroom, providing the perfect setting for a home office, fitness studio, playroom, or additional entertaining space. Upstairs, the spacious primary suite serves as a private retreat, highlighted by a generous view balcony where sweeping sunsets and tranquil hillside scenery become part of your daily routine. The professionally redesigned backyard offers both beauty and functionality, creating an ideal setting for gatherings, relaxation, and enjoying Walnut’s picturesque surroundings. With its oversized lot, the property also presents exciting possibilities for future expansion, a pool, outdoor amenities, or potential ADU opportunities. Located within the award-winning Walnut Valley Unified School District and just minutes from Mt. SAC, Cal Poly Pomona, parks, trails, shopping, dining, and major commuter routes, this turnkey residence delivers an increasingly rare opportunity: a fully renovated view home with exceptional lot size, versatile living space, and room to grow. A standout offering in one of Walnut’s most desirable neighborhoods.
