Once-In-A-Lifetime Opportunity

This unique property is truly a once-in-a-lifetime opportunity. Situated at the end of a private road, this magnificent estate has spectacular views of San Francisco Bay, Arastradero Preserve open space, and the coastal hills. From the existing home, there are no visible rooftops of neighboring properties, ensuring complete privacy and totally unobstructed views. There are two separate parcels, an existing 5-bedroom, 4-bath home of approximately 3,668 square feet, and a pool. Additionally, the property is located in the highly acclaimed Palo Alto School District.

12 Arastradero Road, though centrally located in Portola Valley, is part of unincorporated Santa Clara County. As such, any new construction is subject to review by the Santa Clara County Planning Department and not subject to the Town of Portola Valley’s architectural review or square footage limitations.
