Simple 6x6 tin shed created in sketchup online. Fairly close to factory standards (sizes, standards of beams, bolts etc). This shed design was quite common in the 80's-90's. I did it to give to the local council for shed approval, as there were no plans whe I go it ¯\_(ツ)_/¯
I'm a n00b in Sketchup, so not bad for my second model ever built... still a work in progress.
