We will use this significant landmark as a catalyst for discussion about the end of a building's useful life. Who decides when that is, and how do we determine what the future of the site or building is? How should a building be dismantled in a way that considers its carbon footprint and the ecological impact of its extensive material inventory? How should any future use honor the past of the site while still considering its next iteration? Three experts will weigh in on this important dialogue, highlighting the nuanced considerations for the future that must be considered thoroughly when exploring a decision of this magnitude.
