Effect of double-deck sunken courtyard

Quick answer：

The double-deck sunken courtyard is a landscape design element that creates a multi-level courtyard space. It combines the traditional Chinese courtyard's intimate atmosphere with the modern architectural approach of layering. This design typically features a lower level that is sunken and surrounded by walls or railings, and a higher level that connects to the main building or offers a separate access point. It can enhance privacy, provide a variety of visual perspectives, and create a more dynamic and interesting outdoor space.
