anyone build cabins?

Another option to consider is to build it in a mini barn/storage building style where you build a 2x6 floor system on 4x6 runners. You then set the building on concrete blocks. This style of building isn’t considered a “permanent structure” and therefore isn’t held to the same standards as far as property tax and coding in a lot of areas. Would also give you the option to move or sell it in the future if you wanted to. This is personally the way I would build a tiny home/small cabin.
