Absolutely beautiful gazebo. We paid for pros but there were none in our area, so we did it ourselves. It was not hard, just slow and steady. You need a tall ladder and a short ladder, and four people to move it in place if you do not erect it in its exact resting spot. It is very heavy. When totally fastened together, it feels very strong. I absolutely love it and will buy more! I got the 12x20. It came in six boxes and was not damaged in shipping. I was not missing any parts.
