  Stop by and enjoy this beautiful home!

Set on over 18 acres in South Livermore's wine country, this estate delivers the kind of scale and privacy that's genuinely rare this close to the Bay Area. Six bedrooms, seven and a half baths, a den, a bonus room, and a game room with a full wet bar give the main house serious flexibility for a large family, for entertaining, or both. The loggia with fireplace extends living outdoors, and the pool and spa round out the grounds beautifully. The property also includes an ADU and au pair unit, a five-car garage with shop, and its own Merlot vineyard, a working piece of Livermore Valley wine country right on your land. Inside the valley, you're minutes from Downtown Livermore's restaurants, tasting rooms, and year-round events, and surrounded by acclaimed wineries including Wente and Concannon. Sycamore Grove and Del Valle Regional Park are nearby for hiking, biking, and horseback riding. For commuters, I-580, ACE Train, and BART connections keep San Jose and San Francisco within easy reach.
