Purpose: This study aims to question the fact that density has been considered only as an instrument of calculation to be used on regulation mechanisms, without taking into consideration other variables related to density. The paper proposes a framework consisting of four determining factors for urban analysis that have to be considered before starting a densification process: connectivity and permeability of network, mixture of uses, relation to urban morphology and public spaces for each district. The methodological analysis was carried out for the case of the district of Gruta de Lourdes, Quinta Normal, located in northwest Santiago, which has started a densification process the recent years. Design/methodology/approach: The present discussion aims to obtain objective parameters to determine if urban development allows livability and a balanced relationship with actual urban form and diversity. There appear to be four determining factors of urban analysis: connectivity and network permeability, the mixture of uses, public spaces and urban form development. The district of Gruta de Lourdes will be used to delve into these parameters to place the debate around density in objective terms. To look in depth at each of the criteria for evaluating densification processes, various methods were selected for quantifying the observed variables: to evaluate connectivity and integration of a neighborhood with the rest of the city, the spatial configuration analysis “Space Syntax” will be used; to evaluate mix of uses, mixed-use index, or ratio of non-residential use will be used; urban morphology, plot size, housing density (dw/ha), lot coverage and floor area ratio will be used; public spaces, the percentage dedicated to each of these in m2/inhab. Findings: The results allow us to conclude that it is necessary to plan densification processes via an analysis that promotes connectivity, mixture of uses, urban morphology and the available public spaces to understand density as a multivariable phenomenon. In addition, we conclude that the case study district, Gruta de Lourdes, can withstand greater demand for housing as long as the context is taken into account. A possible option to asset the densification potential could be the “infill” strategy, which aims to be a type of intervention that does not change the structure of the neighborhood as new buildings are positioned among existing ones, maintaining the form of the streets and the structure of plot divisions. Originality/value: The value of the paper is to contribute to the discussion on how to renovate central areas in Latin American cities looking at variables such as connectivity, mixture of uses, urban morphology and public spaces, which are directly related to density. Moreover, the paper contributes to discuss new ways to analyze and measure densification, toward planning a district’s renovation. In addition, the quantitative methodological approach to the densification processes gives a new understanding of how to determine density. Finally, the paper reveals an opportunity to rethink the inner city toward new approaches to renovation developments. |
