Ripensare lo spazio del suolo

1n recent years the relationship between nature and construction has assumed a centrai role in the reinterpretation of the contemporary landscape. The large and increasing number of abandoned and unusable places due to inadeguate soil condi­ tions has raised new questions in urban design. The architect has to rethink these mainly techni­ cal issues in the urban discipline in order to incor­porate and interpret some "silent transforrnations" necessary to reconfigure fragments of landscape, open new forrns of community and define re­newed conditions of urbanity. Through the analysis of some projects ("Agenti Climatici" by the OMA team; "Buckthom City" by West 8; "South Park Plaza at Queen Elizabeth Olympic Park" by James Corner Field Operations) we intend to identify possible operational strate­ gies through processes related to time and "inde­terrninacy" for the regeneration and reactivation starting from the surface topography (Walliss and Rahmann, 2016) of fragile areas.
