Design of Siheyuan with underground garage

Quick answer：

A Siheyuan, traditional Chinese courtyard housing, integrated with an underground garage design represents a modern adaptation of traditional architecture. This design would typically involve creating an underground level beneath the courtyard for parking, while maintaining the traditional layout and aesthetics of the Siheyuan above ground. Challenges include ensuring structural integrity, natural ventilation, and lighting in the underground garage, as well as harmonizing the new design with the existing historical and cultural significance of the Siheyuan.
