I got a 40x60 building built last year. It has 16 foot high walls. I decided to get a local place build it for me as at that time I didnt have the time to do it. After taking pictures of every step and talking to the builders quite a bit, I wish I would have built it myself. It didnt take these guys long at all.
I didnt get concrete in my building yet as I have to research slab floor options in the extreme cold we can have here, and the fact that I love the in floor heat.
I think the total cost for my building was 24000, and about 9000 of that was strictly labour.
I dont know if I would have done it differently either, but for me cost was a factor. When I had compared a pole shed to a stud frame, the stud frame was going to end up being almost twice as much when it was fully completed.
