Interstitial space is a term used to describe the space between human-usable common space. Interstitial space describes the hidden, unusable space in modern buildings reserved for HVAC systems, electricity and networks. These interstitial spaces provide for the essential cardiovascular systems of a modern architectural creation.
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. The Internet is comprised of billions of websites and pages that stretch between the interstitial space of server racks and hosting facilities. Those who use the web never see these machines, yet they are the omnipresent infrastructure that supports and defines the entire connected system.
