Unusual layout - is it legit?

[Guinevere]

I came across this base today, with the town centre stuck right up against the rocks with no space to drop attackers. I can't see this space as being available for clearing on my own base. How did they do it ? Can't seem to post the photo from ipad but the space is up against the dirt track and rocks near the river

No Title

This is the location I'm referring to.

Certainly not legit. Either a bug/glitch or a hack. My money is on hack

Just needs a little trick everyone can makes that happened
