Abstract

Verticalization refers to a transformation process where high-rise buildings become the predominant typology of urban development, leading to changes in morphology and functional fabric. This article examines the urban growth model based on verticalization in the Metropolitan Area of Concepci & oacute;n, southern Chile's most significant urban system. It aims to characterize the phenomenon of verticalization using the theory of density anatomies as a conceptual framework and to explain its localization logic from the perspectives of accessibility and urban planning. The methodology involves characterizing the anatomies of density and verticalization in the AMC. The results indicate that verticalization increased residential density, but population density decreased during the analyzed period. The discussion highlights three key findings: (1) Dispersed verticalization and density decrease; (2) Diverse anatomies of verticalization; and (3) Incidental and differentiating factors of verticalization: the silence and delayed action of urban planning. Territorial planning instruments have not played a predominant role in directing verticalization. Additionally, the relationship between verticalization and accessibility to transportation services is unclear, with variations in the location of high-rise residential buildings.
