Property Description

Set within the coveted Wentworth by the Sea community, this exceptional residence offers a rare opportunity to own one of New Castle's most distinguished homes. Sited at the end of a quiet cul-de-sac and surrounded by meticulously maintained grounds, the property seamlessly blends privacy, sophistication, and the ease of resort-style coastal living. Spanning 3,189 sq. ft., this 3-bed, 3.5-bath home has been extensively improved and meticulously maintained, with substantial recent updates throughout. Elegant living spaces are complemented by custom millwork, rich hardwood flooring, and an effortless floor plan designed for both everyday living and entertaining. The thoughtfully appointed kitchen features granite surfaces, a Sub-Zero refrigerator, Bosch dishwasher, and quality finishes, blending function with timeless style. Designed to embrace its surroundings, the outdoor spaces are equally impressive. A composite deck overlooks beautifully landscaped grounds, creating the perfect setting for morning coffee, summer gatherings, or quiet evenings at home. Every detail reflects pride of ownership and a commitment to quality. The finished lower level expands the living experience with flexible space ideal for a media room, recreation area, fitness studio, or guest overflow, complete with surround sound wiring and abundant storage. Recent improvements including updated mechanical systems, new hardwood flooring, carpeting, cabinetry, appliances, gas fireplace, and whole house generator provide peace of mind for years to come. Life at Wentworth by the Sea extends well beyond the front door. Residents enjoy access to a private beach, heated pool, clubhouse, tennis and pickleball courts, and a lifestyle that is uniquely New Castle. Stroll to the Wentworth by the Sea Hotel & Spa, marina, waterfront dining, and the renowned Wentworth by the Sea Country Club, or enjoy a short drive to downtown Portsmouth's celebrated restaurants, boutiques, theaters, and cultural attractions.
