This secluded end-of-lane property offers peaceful privacy, natural beauty, and sweeping views of Freestone Valley; a true sanctuary for the soul. Developed as a retreat by the Unitarian Universalist Church of Berkeley in the 1980s, the approximately 11.72-acre main parcel includes a two-bedroom, two-bath Dome structure. The Dome is served by PG&E for electricity, a private well, and a standard septic system. Although the structure is in disrepair, the site presents a rare opportunity for a new owner to bring a personal vision to this extraordinary setting. Two additional parcels are included. After entering the long lane from Barnett Valley Road and passing the private road sign, a white pipe and red reflector on the right mark the beginning of Parcel 1, approximately 2.33 acres. Farther down the lane, also on the right, a marker identifies the start of Parcel 2, approximately 4.62 acres. Beyond the next gate lies the main parcel, with a long circular driveway. The One-Way sign leads to the Dome; the drive continues past the structure and loops back to the gate. There is a nice spot for a potential ADU. The property is ideally located less than three miles from Freestone, six miles from downtown Sebastopol, and 12 miles from the Sonoma Coast. This unique offering is an opportunity to create something exceptional.
