First time on market in over 50 years. Three bedroom, two full bath main house with newly remodeled ADU underneath, situated on a one acre-plus lot in the Vista Verde neighborhood of Portola Valley. Residents here enjoy a serene and quiet lifestyle, with sweeping views and quick access to hiking trails, lakes, wildlife and nature. This custom-designed, private retreat was constructed in 1973, with plenty of styling cues from that era. It's ready for your personal remodeling touches, period or modern. The full-height windows in the 12' open beam ceiling living room let in plenty of light, and afford skyline and treetop views. The all-electric kitchen has great cabinet space and is situated next to a breakfast area with its own breakfast bar. The primary bedroom has an en suite full bath, and a full unpermitted bath sits between the other two bedrooms. Sliding double doors with glass inserts open to a dramatic, light-filled carpeted stairwell that leads down to the front entrance, basement and a second entrance to the ADU. Originally constructed in the mid-80's, this 560'+ unpermitted addition was remodeled in 2018. It features it's own entrance from its carport, additional nearby guest parking, a sunken bedroom, generous living room, a split bath with double vanity sinks, stacked washer and dryer, a kitchen with newer gas range, refrigerator and dishwasher, and plenty of storage. There's ample parking in the driveway for six cars or an RV, as well as two car garage parking, one car carport parking and other guest parking. There's an outbuilding off of the driveway for additional storage. Gently sloping lot is fenced on two sides, and dotted with trees. The back yard features a retaining wall and a permitted storage shed with double French doors. With its large lot, this property offers an opportunity for redevelopment, rental income, or just a great platform for updating and making it your own. Hurry!
