When I lived in western Ky I owned a piece of farm ground that was my private hunting preserve. I put a 10x14' Amish built shed on it for a hunting cabin. It had 8' walls. 2 windows, and a regular house exterior door as upgrades. A small wood stove provided all the heat I needed and I built in bunk beds and a counter top. If I had not moved away I would have added a canopy roof over the door. Running water was from a 5 gallon water container on a shelf over the counter and an outhouse was several yards out the door. It was everything I needed to be warm and comfortable whatever the weather. Cost for the shed at the time was about 2K. Sorry, no pics.
