Apologies for disappearing for the better part of a year. Craziness in life and back pain kept me from doing much for quite a while, but I'm setting up something slightly more permanent now.
I'm going to nail/screw these together and create two roughly square frames, with an extra set of connecting beams across the top. Then, I'll add in some extra supports, and leave the two sides on the short ends partly open, to eventually be filled in with some kind of hinged door (The overall area is 6' x 8') and I'll put together a basic roof, sloped at 45 degrees, with the actual roof covering being a simple sheet metal, and the walls will be made of pallet wood nailed on.
Is there anything else I should consider?
