Set on approximately 1.32 acres along one of Sonoma Valley's most coveted Eastside streets, 1265 Castle Road brings together a 3,818-square-foot contemporary main residence, detached one-bedroom guest house, resort-inspired pool and spa, and beautifully landscaped grounds overlooking neighboring vineyards. Built in 2019 and located just moments from Bartholomew Park and the historic Sonoma Plaza, the private, gated estate offers three bedrooms, three bathrooms, and a dedicated office that can function as a fourth bedroom within the main residence. Expansive Marvin windows and doors fill the interiors with natural light and create a seamless connection to the surrounding landscape. Italian porcelain flooring, mahogany ceilings, radiant heat, and thoughtfully selected finishes lend warmth and refinement to the home's clean architectural lines. Designed for both everyday living and effortless entertaining, the residence features generous gathering spaces and a chef's kitchen with premium Miele appliances and a walk-in scullery, all flowing naturally to the outdoors. Meandering garden paths connect mature landscaping, raised garden beds, fruit trees, berry plantings, and wide-open spaces that embrace the property's vineyard-view setting. An outdoor kitchen, fire pit, multiple areas for dining and relaxation, gated entry, and dog run further enhance the grounds. Solar power, battery storage, extensive irrigation, and a living roof complement the estate's thoughtful design and environmentally conscious systems. Pairing contemporary architecture with the relaxed indoor-outdoor lifestyle for which Sonoma is known, 1265 Castle Road is a private and beautifully realized retreat in one of the valley's most sought-after locations.
