Pleased with the final result.  This is a sturdy design.  Assembly takes some time and patience, but the instructions aren’t bad, and the video is helpful.  In my view you must have at least two people to assemble.  three is good, four is better, otherwise it would take a long time.  We did it with two and sometimes three people and we spaced it over three days.  You could do it in one long day.  The trickiest part is the roofing.  You need to be very diligent in ensuring that the panels fit properly into the support plates, otherwise you will have problems that will get worse as you move down towards the eaves.  We found that duct tape was helpful in holding the panels and support plates in place during assembly.  This was a little frustrating at times, but if you take it steady and don’t try to rush it you should be OK.  Otherwise the parts fit together well and the end result is worth the time.
