>>800267Don't build a cabin. If you're almost fully done on the cabin and some ranger finds it and orders you to take it down, then the hard work is wasted.
Don't even build a wattle and daub structure like
>>800804 suggested. It's easier to build, but for wattle and daub you need cowshit, straw, some clay but mostly mud. And it takes a lot of work.
What i suggest you make is a gypsy or bender tent. It's made using curved sticks and a large plastic tarp. If you need insulation or camoflage, just pile a shitload of brush and leaves and logs onto it to make sure it stays on (pile them over the tarp). Then it is like a bender tent with a wikkiup modification.
You can get a stove in there as well, and all you need for a floor if you need it is just a few pallets and mdf or plywood. A lot easier to make than a log cabin or wattle and daub structure.
