When researching projects and project sites one finds lots of interesting things as well as interesting ways to find things. One way to look back in history is through the reference materials generated by the Historic American Buildings Survey. This resource is a wealth of historic information and especially relevant to architects since its the main focus is buildings.
Found the above house while browsing through the online collection. This house was photographed in February 1983. A quick google and bing maps search revealed nothing on Belcaro Road in Knoxville that looks remotely like this. Probably have to do some foot work and a bit more research to find out what happened to this amazing house.
The estate also included a formal garden on the back lawn.
