I bought this for my daughter's yard. Working by myself it took 1.5 days, if you include putting down a base of 12x12 field stones. Some parts were slightly damaged on arrival, with some bending on the ends of pieces. They were easily straightened since the steel is so thin. That's not the manufacturer's fault. assembly was tedious, but I expected that. It was fairly easy. All parts were included. My only beef is the instructions and illustrations. They were somewhat unclear on a couple steps and backwards on the door assemblies. Make sure you lay the FLAT sides of the roof panels OVER the channeled sides to keep rain out. This was not mentioned in the instructions. Once completed it's a pretty sturdy little building.
