This shed is huge, but I was really impressed with how easily it went together. All the instructions are picture based and very clear. Part bags are labeled well and so are the peices. I would consider myself and advanced do it yourselfer, but if you are working off a level and flat surface to start with, about anyone can follow the instructions. If I were to have one complaint about this shed it would be strengh and durability of the floor. I was using a step ladder in the shed during assembly and the legs were sinking into the floor. Once the ladder was removed, the floor came back, but it puts into question the long term durability of the floor. To be safe, I'm going to put down plywood under any heavy objects with small feet so that they do not damage the floor. The manual suggests this. I didn't knock off a star for the floor, but I'd love it even more if it had a really solid floor that I wasn't worried about damaging.
