Completed in 2022 and built by the owner, the home features high ceilings, custom cabinetry, solid wood doors, rich flooring, and extensive marble and stone finishes throughout. The spacious great room serves as the heart of the home, flowing seamlessly to the wraparound porch, backyard, pool, and spa. The main-level primary suite offers a spa-like bathroom and direct access to the covered porch and pool, while upstairs includes a media room and dedicated office. A detached one-bedroom guest house with attached two-car garage provides flexibility for guests or use as a pool house. Owned solar, mature landscaping, and an exceptional location complete this turnkey Sonoma retreat.
