The following landscape techniques can be integrated with terraces and retaining walls or used independently. Because they are all freestanding structures, they can also be used to create multi-level interest in flat yards.
Building a large terrace allows you to build a patio for outdoor gathering, but you can often get more space with a deck. Because they are made of wood and elevated off the ground, decks also have a very different feel than a terrace and can be used to make a multi-level design even more dynamic.
Decks and trellises often go hand in hand. The exposed underside of a deck on the downhill slope can be concealed with lattice work planted with vines. Trellises are also useful around the sides of a deck as a visual screen. In any way you choose to integrate them, trellises are yet another way to add vertical levels to the design.
Living walls can be integrated with retaining walls, attached to the exterior of the home or erected as free-standing structures. They are specially designed structures that provide a growing medium for plants (often succulents) and have a built-in irrigation system. Unlike other vertical structures, they appear as a living wall of vegetation rather than a hard surface.
A boardwalk is an elevated wooden pathway that is built in the same way as a deck. They are easily integrated with wooden stairs and deck areas and are a viable alternative to ground level terrace and stair systems for getting around on a steep slope.
