This shed I built in August. Inside dimensions are 7' D x 12' L x 8' H to the top of the plate. To make it easier to stack, I put 4' wide welded wire up the ends. I don't have the land to stack in drying rows before I put the wood in the shed. With the first leanto I built in 1975, I found that wood in the middle was still not seasoned after 3 years since it is only open on 3 sides as the back is the cinder block wall of my shop. That one there is 8'D x 8' H x 19' L. I think many people might be making a mistake when they board in 3 sides on their sheds. (That is, if they are putting unseasoned wood in there.) I also have another shed I built 3 years ago that is 14' L x 4' W x 8' H at the front & 6' H at the back. That is open on all sides. Here is my new shed. Here is my 1975 shed. I know, it's a lousy picture.
