Kind of reminds me of one of my Uncles one room shack. About the same size if you leave off the additional room on the back. For the past 20 years it even has featured vinyl siding. One thing that made the shack so interesting was that it was so well built with constructed that it is insulated better than most modern houses. Even in the dead of winter, with the front door's window broke out, the shack would be found quite warm even with the wood stove being cold. Still stands today, many decades after it was first built, and is lived in. (Wouldn't mind having it myself if I could get decent internet...)
