assembly was straightforward with clear written instructions and tutorial. assembly took approximately 9 hours. would recommend a recommendation to treat wood components before assembly since treatment is condition of warranty. had to hunt through 4 of the 5 boxes to locate pieces so you'll need,space to set boxes apart and for assemblies as you complete each step. be careful moving the unfinished roof assembly about as the fascia lumber is easily cracked as I found out, not structural.  overall very pleased and would recommend
