Sky courtyard and sunken courtyard design

Quick answer：

Sky courtyard and sunken courtyard design refer to architectural elements that incorporate open spaces or partially enclosed areas within a building. A sky courtyard is a semi-enclosed space located above ground level, often providing natural light and ventilation. A sunken courtyard, on the other hand, is a courtyard that is below ground level, creating a sense of privacy and seclusion. Both design features are used to enhance the architectural aesthetics and functionality of a building.
