It has 21 acres, a 12-car garage, a guest house, and a fancy fountain, and everything's covered in stone. It's your very own English country estate in Alamo (which is near Danville, if you didn't know).

If it feels like you've seen it before, you have: in your dreams—the ones about that long lost eccentric aunt who dies and leaves you everything. You say so long to the city and pick up and move to the foot of Mt. Diablo, where your sprawling new property is nothing short of grandiose. You dream of the kids you'll have someday trotting around the neighborhood on horses and splashing down the slide in their own mini version of Waterworld.

The home was designed to look like 18th Century England but it was built in 2010, and it has all the trappings of modern life required by a sophisticated urbanite such as yourself. Spanning nearly 22,000 square feet, the estate houses 10 bedrooms, 13 full baths (plus nine half-bathrooms), multiple kitchens (including a gorgeous outdoor cooking haven), five fireplaces, and enough space to throw parties for a few hundred of your closest friends.

Speaking of entertaining, you'll be the host with the most thanks to the many bottles in your castle-like stone wine cellar and your home theater with three rows of soft cinema-style seats. When you're partied-out, take to the waters in one of the house's multiple jetted tubs.
