Hi Rooster,
I was thinking of tarps like that to extend the sides of my current setup. I will research local sources. So far, all the parts of the shelter have been someone elses junk. Not only has that been free to me but it also keeps stuff out of the land fills:-)
I have access issues so bringing in a shipping container would be near impossible.
I am planning to build the garage/apartment first but it is also a salvaged barn frame and I have the on-lot sewage system to design, etc first.
Thanks for the thoughts...I have an unusual project here...i
