My husband and I built the 12x10 gazebo on a recent weekend in June (we are in our early 60's). Overall, it was not too difficult. I bought it online, and had it shipped to my home. It came in two very big, long boxes that were wrapped together. Weighed about 500-600 pounds (can't remember exactly). The delivery guy wheeled it all the way up my long driveway and dropped it off right by my patio. There were no missing parts or damaged parts. We built it on top of our brick patio which has a 3" concrete pad under the bricks. We absolutely love the gazebo and use it every day! We love it so much, we just bought the 8x8 size gazebo for another area of our patio. Highly recommend!
