I am currently working on my first shelter. It is constructed of sandbags, commonly referred to as earthbags, and has an inside diameter of 14 feet, giving me a little over 150 sq feet of usable space. I have been working on this off and on for a month now. Hopefully will be begining on the roof with a week or two. The floor is about 7 feet under ground level so once I am completed it shouldn't be noticeable.
this is after the first couple of days
this one and the next couple are at 4 feet wall height
I am currently at 5 feet high with 2 more to go. I have just over 500 sandbags in it now and about 200 more to go. Thanks for letting me share!!
