I got my shack built, and wired. I put a remote switch next to the light switch at the entry door so that when I turn the lights on, I can push the button to start or stop the compressor without having to go out and manually turn it on. The only thing I haven't figured out yet is venting the compressor shed. When they built the shop building, there were 4 sheets of siding left over, and a few small pieces of outside corners. I put the frame up in a few hours (I work real slow---I'm a mechanic not a carpenter) and then the next day I put the siding on. Realized that I didn't have enough outside corner, I had to run to the metal building supply place, actually two of them. The first one (18 miles away) said they had it but it was the wrong color and would have looked odd. So I had to run down to the other place, about 50 miles one way, and they had it in stock. I got 3 pieces which was enough for the whole thing. $36 for all of including 11.125% sales & use tax. Cost more in diesel to get there/back. But all in all, it came out pretty good. I couldn't find a pre-hung outswing door so I had to hang my own. No big deal. Never done it before but it was pretty much self explanatory. Only thing is I had to double and triple check my measurements and cut once. Hardest part was the concrete. 10 sacks of 80lb quickcrete.
I actually built it a little bigger than what it was needed. 5' by 5'2". Same deal for the electric service. 50A service and 6/3 wire. That way if for some reason later on down the road I wanted to put a different compressor (bigger), it's already set up for it.
For some stupid reason the pic keeps uploading sideways. I've tried editing it to get it turned, but it keeps showing up sideways on the site. Dunno. I'm a bit technologically challenged.
