La forma della terra è duratura e contemporanea. La fascinazione per la terra cruda nasce dal suo stato collaterale di materiale di scarto, stigmatizzato come povero e privo di pregio eppure adattabile a contesti climatici e topologici ben differenti. Dopo la rivoluzione industriale, la terra viene relegata ad un ruolo marginale rispetto ai materiali più convenzionali rimanendo depotenziata. La sovrabbondante presenza di terra di scavo e la resistenza verso un suo più diffuso impiego, diventa pretesto per indagare sia la relazione tra materia e forma, sia tra qualità topologiche ed esiti tipologici. Certi del suo potenziale espressivo, l’obiettivo è comprendere come la terra possa inserirsi coerentemente all’interno della scenografia urbana dell’area di San Giovanni (Roma). L’analisi condotta sulla città si focalizza su due livelli, quello evidente della scena urbana e quello sotteso della sua topografia. Il tessuto urbano nasce dalla dialettica tra potere e città, al succedersi dei regimi in carica si sovrappongono diverse strategie insediative che ne definiscono l’anatomia. Due episodi sono essenziali alla comprensione della nostra area d’intervento: la fase imperiale per il sistema radiale di strade consolari, e la fase cristiana con il suo sistema incrociato di basiliche e obelischi. L’area di San Giovanni si presenta come congiunzione tra queste due fasi storiche. L’area racchiusa tra le mura si distingue dal resto del quartiere per la sua natura di arcipelago, in cui ogni oggetto acquisisce autonomia spaziale relazionandosi ai suoi simili in un rapporto di prossimità. Fin dall’antichità, Il rapporto tra la città e il sottosuolo si basa sull’ addizione, la terra custodisce le forme e gli oggetti del passato. La natura sedimentaria di Roma, è tuttora evidente e per certi versi vincolante. La ricchezza di materiale geologico e archeologico del sottosuolo romano si manifesta nell’ opera ciclopica della rete metropolitana, per ogni escavazione infatti vi è una corrispondente estrazione. Tale opera investe anche la nostra area di progetto dettandone alcuni limiti. I tre oggetti architettonici sono sintesi delle precedenti premesse. Da una parte reiterano la natura coordinata dei complessi monumentali e paesaggistici a loro prossimi. Dall’altra tengono conto delle risorse del sottosuolo -la terra di scavo infatti diventa la loro veste primaria- ma anche dei suoi vincoli, pertanto, non vi è mai interferenza fisica tra il tracciato della rete metropolitana sottostante e le rispettive impronte. In conclusione, la ricerca tenta di dare spessore ai limiti di un materiale ancora inesplorato a supporto della sostenibilità della forma, per un’architettura che sia sfondo urbano capace di assorbire le attività e i bisogni imprevisti che il futuro ci porge.

Abstract
The form of the earth is enduring and contemporary. The fascination with raw earth stems from its collateral status as a waste material, stigmatised as poor and lacking in value yet adaptable to very different climatic and topological contexts. After the industrial revolution, earth was relegated to a marginal role with respect to more conventional materials, remaining depowered. The overabundant presence of excavated earth and the resistance to its more widespread use became a pretext for investigating both the relationship between material and form, and between topological qualities and typological outcomes. Certain of its expressive potential, the aim is to understand how earth can be coherently inserted into the urban setting of the San Giovanni area (Rome). The analysis conducted on the city focuses on two levels, the evident one of the urban scene and the underlying one of its topography. The urban fabric is born from the dialectic between power and city, the succession of regimes in office overlapping different settlement strategies that define its anatomy. Two episodes are essential to the understanding of our area of intervention: the imperial phase with its radial system of consular roads, and the Christian phase with its intersecting system of basilicas and obelisks. The area of San Giovanni appears as a conjunction between these two historical phases. The area enclosed by the walls is distinguished from the rest of the district by its nature of archipelago, in which each object acquires spatial autonomy by relating to its fellows in a relationship of proximity. Since ancient times, the relationship between the city and the subsoil has been based on addition; the earth holds the forms and objects of the past. The sedimentary nature of Rome is still evident and in some ways binding. The wealth of geological and archaeological material in the Roman subsoil is manifested in the cyclopean work of the underground network, in fact for every excavation there is a corresponding extraction. This work also affects our project area, dictating certain limits. The three architectural objects are a synthesis of the previous premises. On the one hand they reiterate the coordinated nature of the monumental and landscape complexes close to them. On the other hand, they take into account the resources of the subsoil -the excavated earth in fact becomes their primary dressing- but also its constraints, therefore, there is never any physical interference between the layout of the underlying underground network and their respective footprints. In conclusion, the research attempts to flesh out the limits of an as yet unexplored material in support of the sustainability of form, for an architecture that is an urban backdrop capable of absorbing the unforeseen activities and needs that the future brings.| File | Dimensione | Formato | |
