I purchased this grill gazebo to put on an 8‘ x 8‘ concrete pad. After three years of replacing metal gazebos that just bent in the wind or rusted through the year it was time to make the bigger investment in a nice cedar gazebo. The construction recommends two adults, I took an entire day and did it by myself. I am 6 foot 2, 220 pounds and most of the construction was able to be completed safely with just myself. To place the roof on the top of the structure, You definitely need another adult of equal height and a ladder. For most of the process, you can get it done with just one person, but lifting the roof onto the top of the structure does require a second grown adult. I love the way it looks. I would purchase it all over again and recommend it to all my friends. It’s a wonderful addition to our yard!
