South Korea’s low fertility rate, which fell to 0.78 in 2023, is not just a demographic concern but also an economic, political, and social challenge. Declining birth rates have led to the closure and abandonment of numerous kindergartens, elementary schools, hospitals, universities, apartments, and homes—particularly outside Seoul. These vacant structures, awaiting demolition, represent a significant waste of resources and investment. For architects, historians, and urban planners, they pose urgent design and scholarly challenges. The fertility crisis, therefore, is also an architectural problem. Henry H.
