We are very happy with our new pavilion. Amazed at how well every piece was milled and how they were able to pack it so well! We constructed it in stages, The posts and support structures in a couple of hours, make sure it is square and level. Then assembling the roof panels about 4 hours. The first one is the hardest, watch the videos, they really help. The main thing to know is the roof panels do not fit flush to the wood frame on both sides, just center from the middle. Don't screw anything together and until you are sure everything is square. The second panel was much faster once we know what we were doing. It took the rest of the family to lift everything into place and screw together. We cannot be happier! Looks great. Almost every thing you need to assemble is pre-drilled. Good luck and do watch the videos.
