Interstitial Space

Definition

Interstitial space is a term used to describe the space between human-usable common space. Every dormitory, hospital, hotel and subway has space that is "space between space", or space that exists but is inaccessible and unused by humans. It is the space between space in modern buildings used for HVAC systems, electricity, networks and the essential cardiovascular systems of a modern architectural creation. These liminal spaces are omnipresent and functional, yet generally unseen by those who use the space. Just as the body has organs that help it to function, buildings have their own system that is hidden to the eye but essential in function. Only when a building is built, or it is in need of maintenance, are these interstitial spaces opened and operated on. In the same way, a human body is only opened when restoration or maintenance is needed.
