About this home
Single Family · Built 1981
Far-reaching views of Coal Mine Ridge define this beautifully remodeled home at Portola Valley Ranch, set on nearly one-half acre. Expanses of glass, soaring ceilings, and dramatic skylights fill the interiors with light and volume, while fine hardwood floors underscore a cohesive, modern aesthetic throughout the open main level. Indoor-outdoor living extends across both levels with expansive decks positioned to take full advantage of the natural surroundings. The primary suite with a spa-inspired remodeled bath is conveniently located on the main level and the lower level provides a family room, flexible-use room, and two additional bedrooms and a bath. Adding to the appeal is a full complement of amenities at The Ranch, including pools, tennis courts, a fitness center, vineyard and garden areas, a playground, and miles of scenic trails. A wonderful opportunity to enjoy a close connection to nature with convenient access to both San Francisco and Silicon Valley.
