Inspired by the seller's travels along the French countryside, 1345 San Antonio Road, is a beautifully crafted, classic farmhouse where the timeless character of years gone by meets the comfort of modern construction. Rich in local history, this remarkable gated estate is perfectly tucked into the private rolling acreage that was once part of the historic Olompali Land Grant during the time of President Lincoln. Built in 1999, this custom 3-bedroom plus office/study, 2.5-bathroom home spans 3,070 square feet, perfectly nestled on 25.23 rolling acres in Marin County's scenic San Antonio Valley. Adding wonderful versatility to the estate is a detached carriage house with 3 parking bays, laundry, workshop, and a charming 624-square-foot apartment with vaulted ceilings upstairs ideal for your guests, extended family, or a rental opportunity. Inside, the home captures you with a dramatic great room featuring soaring two-story ceilings, a cozy fireplace, oak hardwood floors, and large Anderson sliding windows that frame breathtaking, panoramic views of the pastoral countryside. The open chef's kitchen, anchored by an expansive granite bar is the heart of the home, flowing effortlessly into the breakfast area, and formal dining room. You will love to gather in the additional familyroom for board games and movie nights, and the bright sunroom for afternoon naps with a curved wall of windows and fireplace. Designed for easy main-level living, the comfortable primary suite offers a custom closet and a private en suite bathroom complete with a dual vanity, shower, soaking tub, and serene views. The warmth of natural oak hardwood floors, central heat + AC, owned solar system, and a water purification system add to the home's everyday comfort. The outdoor spaces invite you to relax and enjoy the peaceful West Petaluma landscapes, whether you are unwinding on the expansive wrap-around porch or hosting dinner on the al fresco Ipe hardwood dining deck. Tucked under the canopy of majestic trees, a sparkling pool and spa offer the perfect, shaded spot to spend sunny afternoons. The acreage is beautifully suited for homesteading, agricultural, or equestrian pursuits, featuring 2 barns, 3 pastures, French country-inspired gardens, a fruit tree orchard, grape vines, olive trees, and a separate wine storage casita. Located just down the road from the beloved Tenfold Farmstand and McEvoy Ranch, this property offers a quiet, bucolic lifestyle.
