The directions was sort of like paint by numbers. There was no actual descriptions of anything It was just pictures and arrows as to where to put screws. The assumption is that you should work with two people but if you wanted to you can do it on your own. It says two people five hours the first one took me about 7 hours and then the second one took me 4 hours and thats working alone. The metal is thin but once you get the whole thing together its actually pretty strong. The two boxes it came in were actually pretty heavy and theres no way you could lift both boxes at the same time but once the unit was completely assembled you can pick it up and move the entire shed as its already assembled and move it from one location to another. This helps especially if youre trying to put the shed into an isolated area. You can assemble it somewhere else in the yard and then move it fairly easy.
