OK a little short on some instructions,  the instructions should contain more details regarding the gutters and when to install them (before roof glazing) and not to tighten hardware until all pieces are assembled. The parts were uniform and accurately fabricated.  For the most part instructions (drawings) were adequate (less the gutter details.  One detail that was missing and I consider important the door is only 5’3” tall great for hitting your head.  All pictures were taking SHORT models.
