Anyone ever just build a cabin?

I have some property I can build on with only two rules:
It cant look like trash, must be constructed of natural materials and built using traditional methods (log cabins, thatch huts, mud huts, boulder and mortar)
OR
It still cant look like trash but must be built non-permanent. Or basically a portable structure (large tent, box truck box, quonset style, dome tent, anything tent)
