About this home

Escape to an extraordinary private sanctuary just minutes from the heart of Guerneville, this unique abode is tucked behind a gated entrance at the end of a hidden county road. Contemporary hillside paradise offers more than 10 acres of unparalleled seclusion making for an exceptional retreat for those who value privacy without sacrificing convenience. Elevated well above the flood zone, the beautifully maintained residence was built in 1992 and welcomes you with soaring vaulted ceilings, rich hardwood floors, and an expansive open floor plan bathed in natural light. 2+ bedrooms and 2 bathrooms, the home is thoughtfully placed within nearly 2.5 fully fenced acres of lush, landscaped grounds framed by majestic redwoods. Designed for those who savor indoor-outdoor living, the property features an expansive entertaining deck, a rejuvenating hot tub, and a bespoke metal roof crafted for longevity. Indulge in the custom outdoor sauna and cold-plunge pool a rare spa-grade amenity that transforms everyday living into a wellness experience. For the hobby farmer or nature lover, irrigated raised garden beds, fruit trees, a small shed/barn, and a charming chicken coop create a self-sustaining environment. A hiking trail just steps from the gate invites exploration of your own tranquil forested hillside. The legally converted garage offers high-speed internet and serves as an ideal library, creative studio, office, or potential in-law space. Generous parking for 6+ vehicles has EV charger plus RV hook up that accommodates guests with ease or supports a possible tiny-home setup. Currently used as a vacation rental, the home is located in a low density vacation rental zone which, under current guidelines, should afford the new owners the opportunity to obtain a vacation rental license. A rare blend of privacy, natural beauty, and contemporary comfort, this exceptional property delivers the feeling of a secluded resort yet sits mere minutes from Guerneville's vibrant shops, restaurants, and riverfront charm.
