Set above the Napa Valley floor and surrounded by expansive views, 1312 Summit is a private estate offering an exceptional sense of space, tranquility, and easy access to both Calistoga and St. Helena. Generously scaled for everyday living as well as gatherings large and small, the property offers five bedrooms, five-and-a-half baths, and a detached guest residence, creating tremendous flexibility for family and guests. Built in 2010 and thoughtfully enhanced by the current owner, the modern Tuscan-inspired residence was created to connect naturally with its surroundings. Retractable glass doors open the main living areas to a generous, covered loggia, extending the living space outdoors and drawing the eye toward an infinity-edge pool and spa with sweeping views across Napa Valley. Inside, the atmosphere is warm, elegant, and inviting. The gourmet kitchen features Brazilian quartz countertops, Miele appliances, and a well-appointed caterer's pantry, flowing easily into the dining and living spaces. A gas fireplace adds warmth to the main gathering area, while the orientation of the home keeps the remarkable views ever present. A separate covered courtyard centered around a wood-burning fireplace creates another memorable setting for outdoor dining, conversation, and relaxed evenings throughout the seasons. Two primary suites one on the main level and another upstairsoffer flexibility and privacy, with each taking advantage of the surrounding landscape and featuring spa-inspired baths and generous walk-in closets. On the lower level, a private theater, wine cellar, and tasting lounge create an inviting destination for entertaining, movie nights, and leisurely evenings at home. The detached guest house is a retreat unto itself, complete with a full kitchen, gas fireplace, one bedroom, and one-and-a-half baths, allowing visitors to enjoy both comfort and privacy. Expansive covered outdoor living areas, a substantial motor court, and a four-car garage further enhance the property's functionality and ease.
