Villa del Prato is a singular gem among Silicon Valley estates. Nestled in the woodlands of Portola Valley on nearly 12 acres of tranquil, private, flat land, the estate comprises three structures: a main house (12,000 sf); an entertainment or business building (6,500 sf); and a pool house (2,000 sf).
Inspired by classic Palladian Italian architecture, each structure is reminiscent of a Tuscan villa, featuring soaring arches, 20-foot ceilings, dramatic skylights, solid stone columns direct from Italy, and the finest-quality finishes. The main home, built on two levels, features a one-of-a-kind 900-square-foot dressing suite that doubles as a safe room. Unseen are advanced systems for the comfort and security of residents and guests.
The entertainment/business building provides an opportunity for customization. With its towering columns, airy loggia, and spacious ballroom, it could be utilized for entertaining, as a home office, conference center, staff housing, or a home for your next startup. Electrical, plumbing, HVAC, and other key systems are fully fitted out.
This grand estate is centrally located close to Hwy 280 mid-way between San Francisco and San Jose, with easy access to major airports and technology and business centers.
