I built 2 myself and then had a 3rd built by one of the pole building companies. There's no comparison in the quality; the pole building is hands down the best building. And it was cheaper than I could have built it with my own two hands. The crew of 4 showed up and started at 9am and was finished and loaded up at 330 the next afternoon. 15 hours total hands on time. All I had to do was write a check. Of yeh I did build the doors. I'm much more pleased wit the professionally built hangar and wish I had done all three that way. Knowing what I know now the pole building is the only way I would go.
