Property Description
First time on the market in more than 50 years. An exceptional land-value opportunity in one of Los Altos most coveted neighborhoods. Set on an impressive 19,900 (appr.) SF parcel, this tranquil property offers a rare canvas for builders, investors, or visionary buyers seeking to create a custom estate in a truly special location. The existing residence consists of a 3-bedroom, 1.5-bath main home, complemented by an independent in-law unit with 2 bedrooms, a full bath, a generous living area, and a kitchenette - for a total of 5 bedrooms, 2 full and 1 half baths. While the structures are ready for transformation, the true value lies in the expansive lot, tranquil setting, and exceptional location. The oversized grounds present abundant possibilities for new construction, thoughtful expansion, or a complete reimagining of the property, subject to buyer verification. Mature surroundings and a spacious footprint provide the ideal foundation for a future luxury residence with ample outdoor living. Just minutes from top-rated Los Altos schools (Almond Elementary, Egan Middle, and Los Altos High), downtown shops and dining, parks, and major Silicon Valley commute routes, this is a rare opportunity to secure a large parcel in a premier location and bring a bold vision to life.
