Defined by the clean lines, soaring ceilings, and abundant natural light that characterize classic mid-century design, this circa 1957 home presents a compelling opportunity in Portola Valley's highly desirable Westridge neighborhood. Unlike many homes of the era, the interiors are bright and inviting, with painted finishes, expansive walls of glass, and a series of eight skylights that fill the home with natural light throughout the day. Vaulted ceilings, versatile gathering spaces, and a thoughtful floor plan create a comfortable environment ready for immediate enjoyment. Equally significant is the setting. Spanning approximately 2.51 acres, the property offers exceptional privacy, expansive mostly level grounds, and a premier location surrounded by some of Portola Valley's most desirable estate properties. Whether enjoyed as it stands today, remodeled, expanded, or reimagined entirely, the combination of land, location, and architectural character creates an opportunity that is becoming increasingly difficult to find in today's market. Further enhancing the appeal is the home's location within the highly regarded Portola Valley school system and its convenient access to Stanford University and many of Silicon Valley's leading technology centers.
