My Shed Plans supplies three different drawings of the same Pole Barn. I am guessing this was drawn by the students at the University of Tennessee. What is helpful is their is more detail shown if you combine all three drawings. This Pole Barn is designed for areas that have less than 10 inches of snow and less than 80 mph of wind. The three Pdf file names are: 5780 Pole Barn 39×60, 5781 Pole Barn 39×60 and 5782 Pole Barn 39×60
