If you have a sloped yard or planting areas that feel a little undefined, the architectural garden trend is built for you. It uses structure first, then layers in planting design, so everything looks intentional in every season. A well-designed retaining wall becomes the framework that makes the whole landscape feel composed, especially for retaining walls on Inverness, IL, or South Barrington, IL, properties where grade changes are common and outdoor living spaces often need clear edges.
