15901 High Knoll Rd Welcome to the absolute best value and opportunity in Royal Oaks! Set on a quiet cul-de-sac, this single-level mid-century residence rests on an expansive 35, 000+ sq ft lot with over 250 feet of frontage, offering exceptional privacy and presence. Spanning nearly 3, 400 sq ft, the home features 4 bedrooms, a versatile den, and 3.5 baths, all arranged in a well-balanced floor plan that comfortably supports both everyday living and entertaining. Original mid-century character shines through clean architectural lines, walls of glass, and a seamless indoor-outdoor connection. Mountain and city-light views provide a picturesque backdrop, while the private outdoor setting is ideal for gatherings and relaxation, complete with a Pebble-Tec pool, built-in BBQ, and fire pit. With significant upside, the property offers a rare opportunity for thoughtful restoration, a modern reinterpretation, or the creation of a custom estate of over 10, 700 sq ft (buyer to verify). Surrounded by neighboring sales in the $10M$20M range, this is a compelling value and a true legacy opportunity in one of Southern California's most sought-after neighborhoods.
