>>3112I'm not sure, frankly. You can see the foundation is at least half a meter above ground, indeed sitting on top of soil that's already higher than the lower one on the left, and it has that red part on the bottom right that might just be grating of some sort, though I'm not sure how that would work either.
A good deal of houses more humble than that one sit at a lower elevation, and they seem to be doing fine. It's hard to tell, but I think that one's safe.
