Villa Tranquilla: One of the last legendary estates of Beverly Hills. Perched adjacent to landmarks: The Greystone Mansion and The Knoll. Located at the end of a prime quiet cul-de-sac. A rare opportunity of an almost two-acre promontory with treetop views of the city. Build your $100 million dream home or purchase two incredible homes, a classic Mid Century and Regency era estate in this serene setting. The combined asking price for both 510 and 520 Stonewood is $29.5M, properties are available to be purchased separately, but preferred to be sold together. Conceptual renderings have been designed with a privacy wall to enclose the promontory. An offering like this rarely comes to market in Beverly Hills.
