have had a few folks request pics of the winter shelter I built for myself.. what I now refer to as my home base..
happy to provide those to you now
After digging out the interior area, small enough so that I didn't require a building permit, I purchased some 4X4's and used some concrete to install them as supports. dug each hole down about 18" for stability, then ran boards around the outer edges for a frame for the roof.. also ran 2X4's across the roof with a 23" separation. I should have gone with 16" as that seems to be more common for rolls of insulation. Then I put up tar paper and metal sheets for runoff purposes.
after that, to enclose the shelter I simply purchased OSB Sheathing, which was under 8$ a sheet and enclosed it!
