The design of courtyard water landscape in a villa involves creating a harmonious and visually appealing water feature within the confined space of a private garden. This typically includes considerations such as the selection of appropriate water elements (like ponds, fountains, waterfalls, etc.), the integration with existing garden structures, the use of native plants to attract wildlife, and ensuring sustainable water usage and maintenance practices. The design should aim to enhance the overall aesthetics of the villa and provide a serene environment for its inhabitants.
