This pool and rock garden is very cool because it combines elements that are always fun to have together, and that is a manmade structure and natural elements. It actually looks like the designer went and picked up some rocks form a quarry and brought them in. When you combine the natural and the man made like they have done here, you end up with a very relaxing and accessible space. I think many people love to feel like they are in a natural setting when swimming in a pol. I think that that sort of landscape design aesthetic resonates on a deeper level.
