Design drawing of a two-story building with a sunken courtyard

Quick answer：

A two-story building with a sunken courtyard design typically features a lower level that is partially or completely below ground level, creating a courtyard space. This design often includes considerations for privacy, natural lighting, and ventilation. The sunken courtyard can be used for various purposes such as a garden, lounging area, or a children's play area. Architectural designs for such spaces often blend indoor and outdoor elements to create a seamless transition between the two.
