If you follow the instructions and take your time ( it's not a race ) you should not have any major problems. I watched a couple of Youtube clips the night before , next morning I went through and assembled all my panels and my Wife gave me a hand to connect the panels and put the roof on. Some of the hole were not punched all the way through and others did not line up so it was just a case of drilling some new holes. Stoked it is a great shed for my mowing gear etc
