>>2049067What you're looking for is called a Scoop Roof Shanty.
These were ubiquitous in the pioneer days of the USA. What you do is build an extremely basic log shanty with big gaps in between the logs, chink them with mud, and put on a roof of "scoops".
Scoops are where you use an axe and some wedges to split a log down the middle. Then, you use your axe and "notch" the flat sides to an appropriate depth every 12 inches or so. You then use your axe and carefully split out the sections in between. If you do it right you should be left with a trough.
After you've made a number of these troughs you lay them Spanish Tile style. One row of scoops with the trough facing up. Another layer of scoops with the trough facing down, covering the gaps. This kind of shanty was usually built with a shed angle roof (one angle).
In this way you can make a strong and waterproof roof using nothing but an axe.
Your minimum gear required to build a scoop roof shanty is a good axe and an auger. The auger is to drill holes for wooden pegs that you will use to affix boards (made from split logs) to the sides of the doorway to keep the logs secure. You can make splitting wedges from any decent wood you find.
Ideally you'd have a nice big saw for cutting the logs, multiple steel splitting wedges, etc. But it was very common to build this kind of shanty with very limited tools, no saw, and no nails.
The whole structure should be built of easy to move logs between 6 and 8 inches thick. It should be small 8 feet x 8 feet or so, although pioneers built them as big as 10 x 20.
Scoop roof shanties often had no windows and no door, a blanket hung in the doorway serving to keep the weather out. They were often built with no chimney. If desired a "fireplace" could be built against one side of the shanty, with the logs protected by mud. One or more of the scoops would be left out on that side of the shanty creating a gap in the roof for the smoke to escape.
