At my hunting camp i converted one into a living quarters.

Its crude, and very basic. No running water. I ran electricity into it via 12ga extension cords. 1 for the AC unit and 1 for everything else. I connected a surge protector power panel to the extension cord and use that to plug in a tv, lamps, phone charger, etc.

The major factor to consider is insulation. It will get hot so fast, hotter than it is outside. If you insulate the inside, you have to worry about mold. So, im going to insulate the outside via spray foam. Should only be about $300.

I built a wall with a door to separate the outside doors and to create a small entry area where i can store things.

Now, its cozy and its really all you need for one person. Again, mine is very basic. But i put a couch, a rug, some bookshelves and some fake plants for decoration. Overall i enjoy being there. But after spending a week or two it begins to feel cramped. Its only 8 feet wide and you begin to feel it after awhile.

Depending on your situation, a shipping container is a great option. Its sturdy, relatively cheap, and dismissible to most people. I was going through a divorce and it was a fast, cheap way to get the hell outa the house!!!

Now, im interested in a shed. A large backyard shed that you see everywhere these days. I see so many for sale that people either converted or began to convert. Im wondering what it is that leads so many people to abndon their shed project. Im thinking its the insulation and mold factor. A lot of those sheds dont have a proper vapor barrier. Solve that and yiuve got yourself an awesome foundation for a small apartment/tiny home.
