摘要:The extension of Santiago’s metro line towards pericentral neighbouhods of social housing in 9x18 lots entails a process of densification and gentrification with the challenge of planning urban regeneration with territorial equity and social integration principles. This requires private/public management and investment at national, district and neighbourhood scale, that approaches to the neighbourhood improvement with maximum standards and high-quality densification that guarantee the permanence of current residents. In this chapter, measures for the development of public space and sustainable mobility are proposed, as well for the rehabilitation and construction of housing for homeowners, extended-households and new residents.
