Perched on an expansive 1/3-acre lot with panoramic views of the Napa River and absolutely no rear neighbors, this semi-custom contemporary home offers the perfect blend of modern peace of mind and outdoor space. While tax records reflect a 5-bedroom layout, the home currently functions as a highly flexible 4-bedroom, 3.5-bathroom residence spread across an expansive, sun-filled floor plan. Step inside to find a light-filled interior completely refreshed with crisp new interior and exterior paint. The main level features open-concept living anchored by a classic brick fireplace, a sun-drenched kitchen with built-in skylights, a bonus sunroom, and a highly desirable main-floor bedroom and full bath. Upstairs, the primary suite opens to a private balcony capturing sweeping, peaceful river views. The heavy lifting has already been done for you with major system overhauls, including: New copper plumbing throughout the entire home. New main water line and a brand-new water heater. New high-efficiency furnace for ultimate climate comfort. Outside, the massive, private yard is a gardener's dream, featuring over a dozen varieties of mature fruit trees. With ample parking and storage space, a sprawling layout with room to grow, and massive ADU potential, this property is a rare find. Enjoy peace and privacy without sacrificing convenience, with easy access to I-80 and the Vallejo Ferry!
