Make certain that you start with a level base and then this shed is fairly easy to assemble. Take your time and read the instructions. Most steps can be done by yourself. But, you definitely need more hands to help mount the doors and some of the roof panels. This is a good looking shed and the parts fit very well. Very innovative construction makes a sturdy, watertight shed without having to use sealers of tape on the joints. Total time to assemble was about 6-hours. If you have help, them assembly can likely be completed in about 4-hours
We bought the 6415 shed in 2009 and it has been perfect since putting it together. At that time (5 yrs ago) the instructions were not very good. It went together OK, just was hard to understand the what parts were what, and what the assembly goal of some pages was. The shed lasted in great shape until December 2013. There was 18 inches of wet snow in one day. It bent the trusses, and the roof caved almost all the way in. To be fair, there were LOTS of other buildings and homes that had roof problems too with this unusual wet snow. This was a once in a century snow, I believe. We were able to jack the trusses back up, straightening the bent parts of the metal trusses as we went. We never disassembled the roof, but the panels went back up with the trusses and it now DOES NOT LEAK. There are lots of screws that popped out of the roof panels, but the roof still seems quite solidly attached. I attached some 2x6s to the trusses and propped them up with a couple more from the floor to provide support for the now-weakened, re-bent trusses. We will see if it lasts another winter. We may order new plastic roof panels, and maybe trusses next year to assure the roof is solid again and it will look better (panels sag a little from being bent, making it look worse than it is). Well, the end of the story is that we needed yet more storage room. Even considering the near-loss of the roof on our 2009 shed, we still liked it well enough that we ordered another shed from Lifetime; the exact same model and I assembled it 5 feet away from the current one. The 2014 instructions were better, or maybe I thought so because I had already assembled one. I think they are better, although the parts identification could still be a little better for some of the metal parts. It took me almost three days to assemble it by myself. I had to innovate some "third hands" for a couple of places where two people were recommended for assembly, but I got by. I did make some mistakes and had some do-overs. I also did some things out of sequence (don't DO that!) that required dis-assembly/re-assembly. You may see in some reviews about assuring a level, square foundation. That is SO TRUE. Whatever time you spend assuring a level surface is time well spent. I built mine on the pure sand of our place, no concrete or wood floor. Our 2009 shed was built the same and worked fine. I was not as careful with leveling in 2014, and had to shove sand in and take sand out underneath the structure as I was assembling it. Wasted a LOT of time, which is part of why it took almost three days to complete. Overall, it assembled well, with steady effort. Would have been much better with another person and a perfectly level base. When you get your shed complete, you will like the way it looks, like the way it works and feel good about buying it.
