Thinking of (possibly) fake building, was noodling around Google Maps looking for some interesting walks in my area, and found these surprisingly widely spaced groups of buildings:
They're pig or chicken farms, if you go on a walk you can tell by the absolutely awful smell. Note the vertical cylinders for food storage in your link. I bet the spacing is mainly due to environmental regulations.
Not that it would have helped me without the rest of your comment — although I've seen a vertical cylinder in a farm in Aberystwyth I'd assumed that instance was fuel, and similar elsewhere were labeled as liquified air tanks.

Might well be totally mundane, but it sure seems odd to me with my complete lack of knowledge about civil engineering.
