About This Home
Hidden behind a private gate, this 59-acre legacy estate offers luxury, privacy, and agricultural infrastructure. Anchored by a private lake and a high-producing 25 GPM well, this property represents the ultimate in Sonoma County land ownership. The custom home was constructed in 2006, with its grand entrance and covered front porch. The soaring ceilings with handsome wood beams and light-filled spaces give a sense of refined craftsmanship and impressive scale. The home features a chef's kitchen, a cozy living room with a gas fireplace, and a spacious den/office (with potential for conversion into a third bedroom). The primary suite looks out over the lake and olive orchard, truly stunning! The wrap-around deck offers numerous entertaining areas and is strategically designed to take in the many views the property offers. A fire pit area off the dining room is the perfect place to take in the sunset from the west-facing home. Out back, additional entertaining and dining areas overlook the olive orchard and lake. A custom outdoor kitchen and additional fire pit anchor this space, perfect for hosting gatherings or spending time with the family. Enjoy lazy days paddleboarding on the lake, or just lounging on the dock watching the abundant migratory birds. The detached garage, completely drywalled and nicely finished with a full bath and office, leaves the options wide open as to future use. A rustic yet well-appointed guest cottage with a full bath and private, west-facing back patio adds charm and function. Next to the cottage is a magnificent cork oak tree, estimated to be well over a century old! Its canopy offers the perfect spot to hang a hammock and catch the gentle breezes the region is famous for. Primed for future expansion, a septic system designed for 6 bedrooms was installed when constructed for future growth. This leaves many options to explore, build a grand estate home on the lakefront site, expand the existing home, or add an ADU. A large (approx. 1,800 sqft.) concrete slab located near the house offers a variety of uses. The land features a perfect blend of rolling hills and flat acreage, ideal for an equestrian facility or agricultural endeavors. With approx. 12 acres of olive trees and its DA zoning, explore Williamson Act eligibility for significant tax benefits. While the property shares a private road with neighboring estates, there is no restrictive HOA. 2315 Mountain Ranch Road, a truly unique offering with limitless potential.
