Yesterday I put the shed together myself in about 10 hours. It would have been easier to have an extra pair of hands to help but as a previous reviewer mentioned, it can be done by one person, with patience and tenacity! I'm very impressed by the quality of the materials, as well as the engineering and design of the shed itself. I believe this shed should last a good long time. The only negative I can share relates to the graphics/sketches in the directions. At times, they were too small or unclear, making it difficult to identify some of the many, many parts, especially at the beginning. But, overall, the directions were clearly written and accurate. In the end, I believe you can't miss with this shed.
