A classic look
When stonewalls follow a curve or radius it seems as though the stone itself is bending.
Stone is a very rigid material, so when building in a curved manner the wall seems to flow with the land.
Usually the landscape of the property or a personal preference will determine what is best suited for the project in terms of material and design.
The examples below include curved stone projects that serve as retaining walls, planters, and elements of a terraced project.
