This product came in several boxes, safely and appropriately packed. None of the cartons were too heavy that they couldn't be easily moved with a standard hand truck. 
My wife and I spent the first afternoon building each end piece. The following day, we built the middle section. With the help of a neighbor, we were able to assemble all three sections of the frame in less than 40 minutes. We had to wait one or two days because of bad weather, but managed to install all four roof sections in about 2 hours time. All In all, we took less than 6 hours to construct the entire gazebo.
