Driven by necessity, various building types have changed their use. Churches that are now libraries, abandoned warehouses turned into cultural centers—and while much has been written on the subject, from N. John Habraken's 1970s Open Building concept to Adamo Faiden's contemporary From Mixed-Use to Diff-Use, today we are experiencing, more than ever, a compelling global debate surrounding housing adaptability. Is it necessary to dedicate so much square footage to offices when, during the pandemic, we realized that a large portion of work can be done remotely? This was one of the central questions during the lockdowns of recent years.
Undoubtedly, buildings are on the radar for what we can do with them in the near future—especially as the climate crisis enters the equation. "The greenest building is the one that is already built," says Carl Elefante. Adaptive reuse and adaptability will surely be the defining terms on the lips of architecture professionals worldwide. Thus, it is time to reflect further on how design can address this challenge.
