Located in the desirable Westridge neighborhood, this 2.86+/- acre gated property borders the Stanford Jasper Ridge Biological Preserve (1,193 Acres) , ensuring this property’s privacy, views and natural beauty. Located on a Cul-De-Sac, the main residence is 6,580 square feet, pool house of 795 square feet, and guest house of 425 square feet. totaling 7,800 square feet. The site of the main residence was chosen to take in views of Windy Hill and the northeast foothills of the Santa Cruz Mountains. The four bedroom, four and half bath main home is situated above the pool and guest houses. Everything is bound together by carefully curated landscaping, stucco walled courtyards, natural stone walkways, imported Italian patio tiles, all integrated to blend into the gentle slope of the property.

The home’s exterior is limestone, that craftsmen cut on-site, and speaks to the details that are evident inside and out. Artisans were engaged to provide hand-cut moldings, forged iron lighting, and railings. But, the home is firmly anchored in the 21st century. The floorplan is a combination of separate spaces including the formal living and dining rooms, and the grand open kitchen, dining and family room with soaring beamed ceilings, fireplace and a welcoming indoor/outdoor dynamic. The kitchen has amazing customized storage, top-quality appliances and an island that supports multiple cooks. A main-level Primary suite has access to a private terrace, and a luxurious bath with free-standing soaking tub. A separate bedroom wing has three additional bedrooms and two full baths. Extra amenities include the temperature controlled 1,200+ bottle wine cellar, private office lined with custom storage with French doors to the grounds, and a separate upper-level family area / work-from-home office or creative space includes a deck that provides tree-top views, a birds-eye view of falcons flying overhead, and amazing star-gazing.

A fully equipped Guest House offers a full kitchen with professional-grade appliances. The space opens to the family room with its soaring beamed ceiling, and from there French doors open to a large outdoor patio with views of Jasper Ridge and sparkling pool and spa. Across the pool you’ll see the Pool House with bedroom / sitting area and full bath. A second patio here enjoys a fireplace and completes the entertainment area, which is embraced by gardens and stucco walls that create an intimate oasis. The gated drive winds through the property to the 2-car garage that also provides 600+/- sq. ft. of easily accessible overhead storage.

This unique property is bordered by a seasonal creek and local walking trails that provide a setting that feels remote but offers convenience like Robert’s Market and Ladera shopping center under 3-miles away. Hwy 280, Silicon Valley’s Venture Capital corridor, Sand Hill Drive, are under 6 miles. Excellent Portola Valley schools.
