shed came in 4 boxes, 1 very heavy box. Took me and a helper 8 hours to set it up and we are pretty handy guys. Can see how it may take others a lot longer. Do not attempt to do solo, a helper is necessary. Set the shed on a level bed of 3/4 gravel and I don't think it's the best base but will be fine. The hardest part was getting the roof trusses together but once getting the hang of the first two it gets easier. The walls snap into place easily and the rest of the installation was a breeze. Great shed.
