I assembled this in a day and a half over a weekend.  Due to pandemic restrictions,  I was working solo. The instructions indicated 2 people for assembly, but it can be done with one.  Some reviews have complained about the instructions.   Yes they are completely pictoral without the usual written commentary.  The only issues I had were with the roof vent and door assembly.  Though with careful review of the pictographs and some trial fittings I was able to complete these steps. An extra pair of hands would have been useful.  How it will handle the snow this winter remains to be seen.   I plan on being diligent in sweeping the snow off the roof.  Please note, the wooden deck was not part of the purchased greenhouse kit but a separate project.
