About this home

Few Happy Valley homes command a manicured, 6-acre estate like this one. Surrounding are redwoods, Japanese maples, a Pinot Noir vineyard and more. Wide decks, a gazebo and sitting areas provide venues for entertaining or enjoying nature. Outdoor entertaining is equally easy on the other side of the home, with an extensive deck adjoining the 60-foot pool. The upper end of the spacious grounds has utilities, making that portion possible for development. The home offers 5 bedrooms. Elevated beamed ceilings are found throughout. A fenced deck invites outdoor entertaining in warm weather, and large fireplaces ward off winter chill. The kitchen has a breakfast bar and adjoining nook for casual dining, and a butler’s pantry sits adjacent. Work from home is easy in the office steps away from the kitchen. Wine cellars accommodate hundreds of bottles. Four oversized bedrooms lie upstairs, served by 3 bathrooms. The 5th bedroom, suitable for an au pair, has a separate entrance and private bath. The principal suite has an exceptional bathroom with a Jacuzzi tub. A 3-car garage (with a 50-amp/240-volt outlet) provides substantial parking and storage space. The acclaimed Happy Valley School is down the street, and further down are Lafayette’s exceptional restaurants and shopping.
