This design seminar aims to investigate the parametric relationship between geometry and architecture element, in this case the relationship between the geometry of atrium and architectural circulation. We will begin by using parametric tools to examine existing architecture examples, which contains atriums and complex circulation systems, with the intention of exploring tensions, functions, and the spatial effects between them. Through this analyzation, students will construct their own geometrical narratives to express the parametric formal relationships of the subject of their studies. Thereafter, these geometrical narratives will be translated into iterations of physical models. This class consists of lectures and workshops, and will utilized both digital and physical media.
