Pretty good quality. Assembly wasn't bad if you are somewhat inclined. It took me about 2.5 days of mostly by myself work. The roof was the hardest part to get to line up. I used tin snips to  trim the angled pieces on one end of the long sides to get everything to line up correctly.  They give you extra hardware/small parts which is great in case you lose or damage them. There were a few small errors in the instructions, but nothing that you couldn't figure out if you're even slightly creative. Overall, I'm very happy with it.
