Walls are specifically built to provide a structural or functional enhancement to a landscape. Popular walls, also known as retaining walls, offer support against a slope, eroded or degraded area and can also be constructed to be a garden bed that is lifted to accommodate elevation. Free standing walls can provide privacy, act as barriers, or provide a distinction between aspects of a landscape. Walls can be constructed with decorative concrete wall block, boulders, or CMU blocks with a veneer finish.
