Grappling With Grape Huts

Grape huts. They are fairly ubiquitous in the Panjwayi; massive mud brick structures used to dry the grape harvest into the renowned Afghan raisins. They also made for ready made strong points for the Taliban insurgents, so I figure I need at least one, if not two or three.

But how big?

Here are some pictures I collected to my Pinterest idea board:

Scale (or the lack thereof) is obviously an issue. The first two seem pretty big. The third and fourth are a bit smaller (if we assume the doors are man height).

But look in the background of this picture:

Those two grape huts behind that fairly substantial Chinook helicopter are the size of small castles! I wonder why one would build a grape drying hut that tall? Unless there are interior floors in the bigger ones?

And compare the LAV to the two grape huts in this picture from the RCR website. They appear to be roughly parallel to each other:

The one on the left is quite tall.

Many seem to have thatched roofs, but I've also read of troops or Taliban taking up firing positions on top of them, so some must have solid roofs as well.

But at least the interior detail is pretty straight forward if I don't worry about the holes to stick the grape branches into for drying.

I figure if I have some grape huts, ditches and walls I can start some skirmishing before I even get any compounds built.
