My brother Richard , who is a commericial real estate appraiser has sent me this great recent aerial view of the Van Nuys Ranch House that San Tong built. The property is marked with a yellow dot and can be readily identified by the tennis courts behind it. After San Tong lost ownership in the house and the surrounding ranch property , the house was turned into a private tennis club and the house , front lawn and swimming pool were left intact to serve as the clubhouse for the private club . The surrounding property was subsequently sold and subdivided.
edited to add :
recent photos of the exterior of the ranch house , and of adjacent barns can be found in this post :
