This is a brilliant design. Every step is clearly illustrated in the instructions. There is a video you can watch which we did before receipt. It took us about 4 hours. Not because it is complicated but because there are about 4 million screws to put in. The lines are clean. The white gives a fresh, light feeling. The louvers close flawlessly. It changed the whole feeling of the deck. We are remodeling the deck and backyard and this was the perfect choice. Highly recommend.
