Buildings That Never Close: Perpetual Architecture

What do Grand Central Terminal, Bellevue Hospital, and the Las Vegas casino floor have in common? They've been continuously open and occupied for decades — sometimes over a century — without ever fully closing their doors. This episode explores the fascinating world of "perpetual architecture": buildings designed for the condition of never being empty. We dive into zone-based cleaning protocols that work around sleeping passengers, N+1 redundancy in HVAC and electrical systems, tunable white lighting for night shift workers, and construction phasing strategies that renovate while people keep walking through. How do you mop a floor that's never empty? What materials survive continuous foot traffic? And why hasn't anyone given this building typology a proper name until now?
