Listing Tools

1265 Castle Road presents a rare opportunity to own a thoughtfully designed contemporary estate on one of Sonoma Valley's most coveted streets. Situated on approximately 1.32 acres on the desirable east side of Sonoma, just moments from Bartholomew Park and the historic Sonoma Plaza, the property combines modern architecture, sophisticated systems, and beautifully curated outdoor spaces in a private vineyard-view setting. Built in 2019, the residence spans approximately 3,818 square feet and features a three-bedroom, three-bathroom main residence with a dedicated office that can function as a fourth bedroom, along with a detached one-bedroom, one-bath guest house. Expansive Marvin windows and doors create a seamless connection between the home's light-filled interiors and the surrounding landscape, while Italian porcelain flooring, mahogany ceilings, radiant heat, and carefully selected finishes provide a warm and refined aesthetic throughout. Designed for both everyday living and entertaining, the property offers a chef's kitchen with premium Miele appliances, a walk-in scullery, and generous gathering spaces that flow effortlessly outdoors. The grounds are equally compelling, with meandering garden paths, mature landscaping, raised garden beds, fruit trees, berry plantings, a living roof, and wide open spaces overlooking neighboring vineyards. Outdoor amenities include a resort-inspired pool and spa, outdoor kitchen, fire pit, gated entry, dog run, and multiple areas for dining and relaxation. Sustainable features such as solar power, battery storage, extensive irrigation systems, and a living roof complement the property's thoughtful design and stewardship. A distinctive offering that pairs contemporary architecture with Sonoma's indoor-outdoor lifestyle, 1265 Castle Road is a private retreat in one of the valley's most sought-after locations.
