Ribcage is a curvilinear, inhabitable architectural form inspired both by the geometry of a saddle and the underground plaza in front of the International Affairs Building at Columbia University. Its flowing arches invite interaction, transforming a traditional wall into an experiential space while exploring access points and the relationship between interior and exterior, private and public. The piece examines how architecture can mediate experience, guiding movement, perception, and connection within a sculptural, functional environment.
