The directions clearly state that this takes two people to assemble. As a single lady, I was concerned. It probably took me about 12 hours, but I did build it all by myself. The only part that needs a second person is ironic. All the way around the shed, there are nuts and bolts holding the sheets together. I can’t reach my arms from one side to another to do this. I literally need a four-year-old to hold the bolts on one side while I screw in the nuts on the other. Haven’t done that yet, but I will get to it. This is a great little shed. I’m impressed.I did think it had a floor, but it doesn’t. That was probably my misunderstanding.
