A rare opportunity on 1.31 private acres in Orinda's Monte Vista neighborhood, 5 Oak Flat Road has been held by the same family for over five decades and is now ready for its next chapter. The mid-century home spans 4,674 sq ft across two stories, with an architectural sensibility defined by panoramic floor-to-ceiling windows, walls of sliders, and unobstructed views of Mount Diablo and the surrounding canyon. The commercial kitchen - 36" wok, restaurant-grade fryers and grills, stainless appliances, generous pantry - anchors a thoughtful entertaining layout that flows to dining and living spaces open to the views. The bedroom wing offers private patios and lawns edged by terraced landscaping; the upper-level studio provides additional flexible space with balcony access and more views. Notable features include 600-amp electrical service, a three-story elevator, a 2-car garage (currently multi-use, easily reconverted), 6+ car driveway, heritage oaks, a 15-ft fiddle leaf fig, and a koi pond framework at entry. Structural components and foundation are in great, solid condition and accessible for easy maintenance. Septic will require upgrade; sewer main runs through Oak Flat for straightforward tie-in. Award-winning Lamorinda schools, parks, trails, shopping, restaurants. Minutes to BART, Orinda Village, Hwy 24. (NO OPEN HOUSES- TOURS BY APPT. ONLY)
