The materials arrived on time, and it took about 45 minutes to unload, thanks to a very helpful driver. The building was fairly easy, but the instructions were a bit hard to understand. A lesson from IKEA may be helpful here. Also, pre-drilled holes would be a big help. The door frame was easy to assemble, but due to the hinges not being placed in the right spots, one door catches the frame on the bottom, and the other on the top. An adjustment helped a little. The doors are also a bit far apart that the lock does not work, the bolt is simply too short to catch the opposite side. Other than that, the building is very nice looking and is a great addition to our back yard.
