About this home

Welcome to 21888 and 21886 Blue Oaks Place, an extraordinary custom estate built/designed by PPG. Perched on a private, sun-filled knoll, this serene retreat offers remarkable privacy and tranquility, close-in (5 minutes from 280), yet free from highway noise. Designed in a timeless California Refined Living style, the property spans approximately 9373 sq ft (including garages, main house and ADU), across 2 separate but adjacent parcels totaling approximately 8.16 acres. The main residence features 6 beds/6.5 baths, with flexibility for a 7th ensuite bedroom, or live in quarters, and area for a potential media/bonus room. The 3 car garage adds convenience & functionality to the main house, while a separate studio/ADU and 2 car garage is located on the adjacent property. Flooded with natural light throughout the day, the home enjoys sweeping views of the Western hills. One of the property's most compelling features is its potential to become a true family compound. With a total allowable MFA of 7,595 and MDA of 11,430 at the 21886 parcel, there is an opportunity to build a substantial second residence, adjacent to the existing ADU and two-car garage. There is also expansion potential remaining at 21888 if desired. Los Altos Schools: Gardner Bullis, Egan, and Los Altos High School
