A rare opportunity to own one of Clayton's most unique and inspiring equestrian properties--where lifestyle, vision, and natural beauty come together on 10 usable acres at the base of Mt. Diablo. At the heart of the property is an impressive 25-stall stable, originally constructed at a cost of approximately $800,000, with a thoughtfully designed 1,800 sq ft residence perched above--offering a comfortable living space with a commanding view over your private ranch. Whether you're an equestrian professional, investor, or someone seeking a legacy property, the infrastructure here sets a powerful foundation. The land itself is where this property truly becomes extraordinary. A cleared upper homesite awaits your dream estate, positioned to capture breathtaking, panoramic views of Mt. Diablo and the surrounding rolling hills. With neighboring properties featuring million-dollar homes, this location offers both prestige and long-term upside. Extensive improvements have already been envisioned and partially completed, saving both time and cost for the next owner. These include a developing trail system leading to the homesite, a terraced garden area carved into the hillside, an arena area with significant soil preparation already completed, a tank house supporting the water system, greenhouse, raised garden beds, and chicken coops--creating the beginnings of a self-sustaining ranch lifestyle. Marsh Creek gracefully runs through the property, adding a rare and tranquil natural feature that enhances both the setting and usability of the land. This property presents a compelling opportunity for a private equestrian retreat, a horse boarding or training operation, or a visionary estate build in one of Contra Costa County's most sought-after rural communities. Dream it. Build it. Live it.
