My cabin is a 12'x12' pre-fab with one window, a screen door/door and a 4'x12' porch with overhang. It has three bunks and is RV wired to run everything on a single 12V deep cycle charged by a solar panel. My buddies and I affectionately call it "The Garage-Mahal" It does the job on 600 acres in Greene Co., GA bordered by a national forest and farms. Sometimes I even hunt out of it.
