Portola Valley, California 94028
Beautiful (Bonita!) very large property in upper Los Trancos Woods. Over 1.6 AC of mostly flat land with old, mostly not habitable House, Cottage, Garage and Carport, comfortably spread throughout the property. In Feb 2026, San Mateo County approved a 2 lot subdivision, and work is ongoing to complete the final map recording. The house is available prior to recording of the subdivision as a single lot for buyers who might want more flexibility in what they do with the property. Extensive geological, geotechnical, arborist, historical, biological and civil reports and plans come with the property.
Property is land value only, full reconstruction required.
Built in 1945 and explicitly described in the listing as 'mostly not habitable,' these structures are over 80 years old with no evidence of renovation. The property is being marketed for its land value and subdivision potential rather than the existing improvements.
The property has a large lot size, which is more than 4 times of its living area. lot size in square feet = 70479, living area = 870.
The property features a San Mateo County-approved 2-lot subdivision, offering significant investment upside and flexibility for developers or those seeking a multi-structure estate.
Boasting over 1.6 acres of mostly flat land in the prestigious Los Trancos Woods, this lot provides a rare and highly desirable canvas for luxury new-build construction.
The existing house, cottage, and outbuildings are largely uninhabitable, meaning the property is essentially a land-value play requiring a complete teardown.
While the subdivision is approved, the final map recording is still ongoing, which may introduce timing uncertainties for buyers looking to immediately utilize the separate lots.
No exterior & parking available.
