You don't need to be a contractor to build this, just patience and 4-5 people to connect the 4 posts and to put the roof panels on. I would make sure to watch all the videos on the website before building it. They give great tips, especially when you have to slide the metal strips over the roof, use the dish soap trip. Great customer service as well, I damaged a part myself and they sent me a new one for free.
Bought this from a warehouse store a few months ago. Had it installed by a local company. It looks better than more expensive products. I expect this to last a long time.
Installed last May and have enjoyed this unit. Whether we are entertaining or just reading a book this unit has been a great success for the whole family.
