Current challenges to America's office sector need not spell the death of the American city. In fact, urban office buildings and their surrounding downtowns have a distinct advantage over suburban or nonurban developments. Data suggest that while American office workers prefer the flexibility of work-from-home or hybrid work arrangements, they are still flocking to cities to recreate. This change began even before COVID, as miles of waterfront from Pittsburgh to New York were rejuvenated and activated with retail, restaurant, park, and residential uses. These well-programmed, lifestyle-focused urban developments have proven to be attractive alternatives to an increasingly online world and magnets for investment and urban innovation. The office sector's headwinds are an opportunity to rethink America's downtowns by transforming single-use, commuter-focused blocks of office buildings into places where people want to spend their leisure time—replacing central business districts with central social districts. By thinking of our downtowns as homes for social activity, we can expand the realm of what's possible and fill city centers with activity, life, and commerce.
