Best Wall Design? Or Just a pattern?

So I was experimenting on my base and I cleared everything out. And I noticed that the yellow greenish squares on the ground sort of resembled a wall structure. And so I started to put my walls on the green squares and it would actually form a smart structure for a base. Now I'm not TH10 so I don't know if it required all walls. But I was placing buildings and traps in good places and the base proved to actually be of good use(to me). Or this whole structure might just be just pattern. Or maybe the best wall design for a legit base out there I don't know. Now I don't know how to post pics on this game, but I suggest you all check it out and try it out for yourself.
