Discover your ultimate West Sonoma County retreat. Tucked at the end of a long private drive, this classic farmhouse estate offers quiet seclusion, mature landscapes, and the perfect blend of historic warmth and modern luxury. The beautifully remodeled main residence, built over a century ago, and over 3300 sq ft, preserves its original character while offering light-filled, open living spaces designed for today's lifestyle. Large windows frame the multi acre property, creating a seamless connection between the home's historic charm and the natural beauty outdoors. More than just a home, this property is a complete country compound. The grounds feature a detached one-bedroom cottage ideal for guests or rental income alongside a light-filled artist's studio and two large, versatile barns. Step outside to your private oasis to find an updated workshop/pool house and a sparkling pool perfect for warm summer days. Thoughtfully future-proofed for modern, sustainable living, the estate includes owned solar, battery backup, and two Tesla charging stations. This is a rare opportunity to own a timeless, fully equipped country estate that feels worlds away, yet remains just minutes from town amenities.
