Rich It’s definitely possible for one person to put this shed together in one full day. While the instructions are clear, the only glitches I encountered were self induced. I skipped ahead and placed screws in the base that threw off the alignment of the door. When I removed the screws, it aligned perfectly. Having read it would be useful to have a second person pushing down on the roof to set the interior screws, I used the uninstalled door panels to add the needed weight. This is great workaround for solo assemblers! 
Anne The shed has an attractive, modern design, is functional, and has held up to Florida rains. We may consider painting it white to blend in with our fence. We’re very pleased!
