  • Hilltop Retreat with Sweeping Western Hills Views




    Property Overview

    If living in a bucolic Portola Valley setting with a sweeping 180-degree view of the Western Hills is your dream, then this is your property.

    This oak-studded private lot of approximately 2.86 acres has magnificent views of western hills and the surrounding canyon. Set back from the street by a very private driveway approach, the sun-swept lot has a large building pad with an existing one-story, 4-bedroom, 3-bath home and detached 1-bedroom, 1-bath studio, tennis court and pool.

    Build your dream home or break ground on a spectacularly designed contemporary home imagined by Robert Arrigoni, founder of Backen, Arrigoni & Ross (now BAR Architects) in San Francisco, CA, with landscaping by renowned landscape architect Andrea Cochran of San Francisco. The town-approved plans and construction documents are ready to go. The approved, custom-designed, one-level, 6,728-square-foot home (including 4-car garage) has a large primary suite with two walk-in closets, an open-plan living, dining, kitchen, and entertainment area, an exercise room, two dedicated home offices, plus a basement for a utility room/storage and a wine cellar (accessed by stairs through the mud room and an elevator). In addition to the main house and 4-car garage, there are two one-bedroom guest houses and a separate ADU.



    This hilltop retreat seems miles from the chaos of Silicon Valley, but is, in fact, within close proximity to shopping, dining, and top-rated Portola Valley schools. With convenient access to Sand Hill Road, Stanford University, and commute routes, this property is a one-of-a-kind opportunity to live in your tranquil dream home.
