About this home

Completed in 2006, this magnificent vineyard estate is the perfect place to escape from the fast daily pace of Silicon Valley. The approximately 41 acres are as peaceful as they are beautiful, with spectacular top-of-the-world San Francisco Bay views. Arriving on the front terrace is as if stepping into the Italian countryside. The scale of the home is destined for grand entertaining spilling out to exceptional front and rear terraces. The kitchen is a culinary retreat with commercial-quality appliances, and the wine cellar awaits a sizable collection. Multiple rooms for everyday living, a theatre, plus a well-being center with spa, steam, and sauna add luxurious touches. Both 5660 Alpine Road and APN 080-040-120 are being offered for sale together.
