There are many cases where using stones and rocks in a yard design work great. In many cases what people will do is use artificially cut rocks and stones for their yard design, but in this case it looks like they have used natural rocks and stone for the design, and I really like how t turned out. This is not easy to pull off because you have to find the right rocks to make it work. I almost wonder if they found some of these at a rock quarry, or even at a river. In any case, it looks really wild and natural.
