Introducción Estado del Arte Hipótesis, interrogantes y objetivos Metodología By choosing these case studies I have opted for discovering lesser known interventions, except Bilbao and La Mina and avoiding the most famous Orcasitas, Vauban, Trinitat Nova…. Even I have included two projects not built yet: San José de Valderas, which follows the mechanisms provided by the Law 8/2013 and Orba, which proposes a flexible performance, with high sensitivity to social issues. The mix of combining finished projects and proposals adds richness to the study. The sixth part, apart from the conclusions, outlines some possible applications, further research and new fields of research.
