The old family farm, in Indiana, had all these short "barns". Because they were from Germany, they couldn't figure out how to build properly footed foundations, in the Indiana wilderness. The result was the bottom logs of the houses kept rotting out. So, every 10-or-so years, they'd just build a new log cabin. The old log cabin was the new barn. And, yeah, the old growth logs meant most of the cabins were only 4 logs high, since each log was 3' thick, after they were squared up. By the time the cabin rotted out the second log, the last logs were dry enough they'd stop rotting. The farm had a number of these weird, short, log cabin barns.
