not mention all work must be done by you only.People who deliver supplies,or nosey hunters. will wonder what your deal is .Just cause your in the middle of nowhere doesnt mean you will blend in. if you want rent trac-hoe(and no not one of those gold digging girls who hang out at the race track) dig a hole 10 x 10 8 deep or what ever. Lay up with block. Use pressure treated 4x6 on top. then build simple shed on top.Inside have a little wood stove sitting on a metal plate or somthing.Make it somwhat easy to move cause under there is where your access will be to the basement. Also run all water ,elec, ventilation under ground to there proper places. while having hoe. This can all be done easly going with all good equip,elec. supplies and materials, hoe rental. In the 3-4k price range.Maybe cheaper depending your supplier and area you live. But most of all you can pick up all the supplies yourself with a pickup truck and build discretely. I know this cause i make up things like this in my mind for fun. I would never try such a setup:thumbsup:
