That looks about like the box stands we use in Louisiana. Some are made of wood, some are made of other materials, but scrounged lumber is probably the most common construction material. My brother-in-law is a professional carpenter and he's been building them to be as lightweight as possible and to disassemble in panels so that we can move them when conditions change or when materials rot.
Mine has lots of the comforts of home and if I could figure out how to put a flush toilet in one corner, I might never have to come out of the blind. It's my little bit of heaven as well.
