Interstitial spaces in architecture

Interstitial spaces in architecture refer to the unoccupied or open areas between main structures, such as gaps, courtyards, corridors, or buffers within a design. They serve to improve spatial relationships, facilitate movement, enhance natural light and ventilation, and create a sense of openness. These spaces are intentionally integrated to connect different parts of a building or outdoor area, contributing to the overall flow and functionality. Essentially, interstitial spaces act as transitional zones that improve the usability and aesthetic quality of architectural layouts without being the primary rooms or structures themselves.
