The design of a sinking courtyard landscape in a club involves creating a harmonious and visually appealing outdoor space within the club's architecture. This typically includes considerations for the layout, vegetation, water features, lighting, and materials to ensure the space complements the club's ambiance and serves the needs of its patrons. Key aspects might include naturalizing the transition from indoors to outdoors, incorporating privacy elements, and creating a sense of tranquility or opulence, depending on the club's theme and target market.
