Over the past decade, building permit statistics in Seoul reveal an intriguing structural shift. The number of new construction projects has undergone a notable contraction, falling significantly from approximately 7,000 to around 2,000 annually, while architectural interventions in the existing urban fabric, such as extensions and renovations, have remained remarkably stable at between 2,000 and 3,000 cases. As a result, the proportion of renovation projects has steadily risen while new construction has declined. Several factors account for this transition: land available for new development has become chronically scarce, the costs of building materials and labor have surged, and, above all, the urban built environment itself has reached a state of historical saturation. |
