View of roof, most sheets are second hand, as the rafters and purlins were also. I started with a 100x50 on its side, than a 75 by 75, than a 100x50, than finally a 100 x 50 on its side with a 100 x 50 upright, the last two beams are bolted together. This is a low fall of 50, 75, 100, and 150mm over a distance of 4m. Or 100mm over 4m.
