The property offers remarkable privacy and an inviting connection between indoors and out. The villa occupies 9.15 acres, while the cottage rests on its own 2.5-acre parcel. Vintage architectural elements, sourced from around the world, distinguish the villa and include repurposed oversized doors, distinctive fixtures, custom plaster walls, and high ceilings that are accented by beautiful exposed wood beams. Arched windows, and balconies adorned with intricate ironwork, reveal stunning views of the panoramic valley, as well as intimate scenes of garden courtyards, lush plantings, and majestic oaks. A Rumford fireplace anchors the living room, while the kitchen features custom cabinetry and Caesarstone countertops. An expansive deck off both rooms embraces panoramic views, complete with automatic screens enclosing a portion for outdoor dining. The villa offers a generous primary suite, a guest bedroom, a flexible den suited to a media room or third bedroom, a separate dedicated office, with an elevator providing convenient access between the two levels. Meandering stone paths connect secluded gardens, flowering arbors, numerous varied fruit trees, and garden terraces with layered plantings and custom stonework. The grounds are beautiful settings for gatherings or a quiet retreat. Extensive uplighting and downlighting illuminate the grounds after dusk, including the path between the two residences. Along a gentle path beneath the oaks, and a short distance from the villa, sits the studio cottage in its own private setting. Its open layout includes tiled floors, a full kitchen and full bath, and panoramic windows with expansive views of gardens, vineyards, and the Mayacamas mountains. On this parcel, the pool, and a separate spa on the deck, both each enjoy sweeping views of the surrounding hills and valley. Lounging and dining patios complete this private guest retreat. Separate addresses, gated paved driveways, wells, and backup generators provide independence for each parcel. Just above Glen Ellen, the estate is close to acclaimed restaurants, wineries, a gourmet market, and nearby parks, approximately 20 minutes from Sonoma, 40 minutes from Charles M. Schulz-Sonoma County Airport, and 1.5 hours from San Francisco.
