This shed took about 6 hours to assemble by myself. It would have been quicker with a second person, but wasn’t necessary. The directions were good enough to get it assembled properly. All the screw holes lined up, nothing had to be drilled out. The biggest PITA was peeling the thin protective film off the gable and door panels. Unfortunately some of the panels got a little bent, creased or wrinkled during shipping, but it’s a shed in a box so, no biggie. I build mine on a wooden platform I assembled for this so I left the additional floor bracing out. That would have made using the space more cumbersome. 
This was a perfect solution to a short term storage need. I don’t expect this to survive a very long time in Western New York winters, but building a solid frame wooden shed just wasn’t an   option right now.
