I recently purchased the house next door to our and moved my mother in there. The bonus is there was a small 12'x16' shed in the backward which has been claimed as my shack. It was already insulated and had a small window unit to keep it comfortable.
I painted a couple of the walls and put carpet in the lower half as well. Eventually I was able to move in my late grandfather's desk (which is nearly 100 years old) and am using it as my radio desk. Still working on getting everything set up, but it is slowly coming together.
