I just finished a 25x40x16 high. I purchased metal end walls with the building. When you do that you get 2 pieces of overlapping angle trim for the ends that make a 3 inch wide channel. The end walls are cut to fit and then go into that channel. We used a rented scissor lift and put up full rings. Instead of caulking which would be a royal pain during assembly, I had the entire building spray foamed with closed cell. It is now like a giant igloo cooler! One 18000 BTU window unit cools the thing easily even in Florida Summer!
