For sale: $135,000,000. Perhaps America's grandest estate, certainly an architectural, natural and historic treasure, Green Gables Estate is extraordinary on multiple levels. With its seven homes situated on 74 private acres, featuring breathing panoramic views of California's Pacific Coast range, it is remarkably situated in the heart of Silicon Valley. Its unique combination of civilizations and natures best are brilliantly on display from the exquisitely scaled main residence and its world class gardens, the six additional homes, a stunning Roman Pool, three swimming pools, a tennis court, a beautiful stone tea house, a large spring-fed reservoir (supplying much of the estate's irrigation needs) and a glorious flower and vegetable garden. Portions of the estate offer the potential for a myriad of uses, including vineyards, an equestrian center or expansive orchards. With its two private roads, wooded trails, and endless tranquility, this incredible estate is the ultimate family compound or corporate retreat.
