Around here, before they changed the tax setup, I'd see dairy barns that were simply spotless. That was a business property and taxed differently. The house, on the outside, would look terrible. Inside, very nice.... One thing here, is that a large structure like a barn was a lot for a family project, especially if they were busy farming. So some area carpenters specialized in building / repairing barns. There are several old barns here, built by the same guys, they look similar. I guess because it worked. There is one old round barn here, I was in it about 20 years ago, it is built around a central silo, and the hayloft has chutes that let you drop feed into the cow stalls underneath. Quite a labor saving setup. I believe it was built before WW1. I drove by it this aft, it looks sad, the roof is starting to go, the owners put a blue tarp on it. It's going to take a lot more than that to save it.
