What is the MINIMUM you can get away with for a 'Cabin'... You know, hunting 'Lodge', fishing 'Cabin', woods 'Shack', just someplace to camp and stay over a few nights mostly... I'm running into more and more of the 'Yard Barns' out in the woods in different places. These can run from basic sheet metal 'Squats' to the much nicer and larger 'Mini Barns' you find on lots for sale... What is the 'Minimum' you could get by with if you had to spend say, a month there!? Would you build a shower and how would you do it? Would you set up a 'Camp' around the 'Cabin', or would you start building onto it like a house? Would you prefer something portable on a 'Utility Trailer' or something more 'Permanent'?
