The need for more dense and vital cities has been promoted by academia since the 1960s and by international organizations since the 1980s. On the other hand, the last census showed that the district of Santiago started gaining population, a process not seen since 1970, while peri-central districts exhibit high real-estate dynamism. In spite of this, the densification of residential areas is increasingly resisted by traditional residents, for whom the high-rise tower, the typical way to densify cities in Chile, is a detriment in their quality of life. The present work provides an alternative model to the traditional form of contemporary residential densification in Santiago, one that promotes higher degrees of urban vitality and a closer relation between private and public space. An exhaustive compilation and analysis of what was built in the last ten years in a sector of San Miguel, in Santiago, allowed us to identify the main trends of real estate development in the area in terms of building height, type and size of flats and ways of relating to the street. This allowed us to build a ‘trend scenario’ for the area. At the same time, an ‘alternative scenario’ was proposed for the area, one with a closer contact between the building and the street, decreased average heights and a densified interior of the blocks. This scenario punished the constructability of the area by 18%. The alternatives were shown and discussed with applicants to programs DS 49 and DS 50, in two focus groups. The results show that approximately half of the applicants preferred the alternative scenario over the trend-based one, arguing that the former gave a better control on the street. It seems therefore, that innovation in urban architecture is feasible technically and politically. We argue that in order to do so, urban instruments should incorporate a more comprehensive vision of the city, not only aiming at achieving certain density thresholds and heights, but also incorporating aspects that promote street vitality. Also, the feasibility of applying some incentives to private developers for the development of architectural proposals is discussed. |

La necesidad de ciudades más densas y vitales viene siendo promovida por la academia desde los sesenta y por organismos internacionales desde los ochenta. Por otro lado, el último censo mostró que la comuna de Santiago ha comenzado a revertir la pérdida de población de los últimos cuarenta años, mientras algunas comunas pericentrales muestran un gran dinamismo inmobiliario. A pesar de los anterior, la densificación de sectores residenciales es cada día más resistida por los residentes tradicionales, quienes ven en la forma más frecuente de densificar, la torre aislada de gran altura, un deterioro en su calidad de vida. El presente trabajo estudia la factibilidad de un modelo alternativo a esta forma de densificación, una que fomente la vitalidad urbana y una relación más estrecha entre el espacio privado y el público. A partir de un registro exhaustivo de lo construido en los últimos diez años en un sector de la comuna de San Miguel, se caracterizaron las tendencias de desarrollo inmobiliario en términos de altura de las torres, tipo y tamaño de los departamentos y formas de relación con la calle. Esto permitió definir un escenario tendencial para el sector. Además, se diseñó una propuesta alternativa que, disminuyendo la constructibilidad en un 18%, genera una relación más estrecha con la calle, disminuye las alturas en forma significativa, densifica el interior de la manzana y aumenta el comercio de escala barrial. Los escenarios tendencial y alternativo fueron mostrados y discutidos con postulantes a los programas S 49 y DS 50 del Ministerio de Vivienda y Urbanismo, Minvu, en dos grupos focales. Los resultados mostraron que alrededor de la mitad de los encuestados dijeron preferir el escenario alternativo por sobre el tendencial, valorando el mayor control que ofrecía esta tipología sobre la calle. Lo anterior sugiere que existe espacio técnico y político para plantear propuestas alternativas a la torre aislada de gran altura. Para que ello ocurra, es necesario que los instrumentos de planificación incorporen una visión de ciudad más comprensiva, que no se limite al establecer umbrales de densidad, alturas y acercamientos máximos, sino que también integre aspectos que promuevan el control de la calle. Asimismo, se discute acerca de la posibilidad de aplicar incentivos en constructibilidad para el fomento de soluciones arquitectónicas que incrementen la vida de las aceras.
