I assembled the gazebo in 10 hours by myself and must describe the experience. I’m not sure why the upper perimeter boards need to be 5 pieces on 4 sides. It adds more errors to the finished product. When assembling, three boards are joined, then the second board has two pieces and is joined. Then the two are joined. The has to be done on each of the 4 perimeter boards assemblies. It is a lot of trial and error to get them to match in length. Why not make these in one segment or two if shipping is overly expensive because of the length. The width of the 20 segments on the above varies a 1/4” between the 20 pieces that make up the 4 perimeter boards. Thirdly, the head of the screws for the slotted holes in the roof panels don’t have much overlap to secure the panel as good as it could. The holes in the boards that attach to the post are not very close between the 4 assembled pieces as they attach to the posts.
