La costruzione razionale della casa. Scritti e progetti di Giuseppe Pagano

The rational construction of the house. The writings and projects of Giuseppe Pagano Description, themes and research objectives The research aims at analysing the architecture of Giuseppe Pagano, which focuses on the theme of dwelling, through the reading of 3 of his house projects. On the one hand, these projects represent “minor” works not thoroughly known by Pagano’s contemporary critics; on the other they emphasise a particular methodological approach, which serves the author to explore a theme closely linked to his theoretical thought. The house project is a key to Pagano’s research, given its ties to the socio-cultural and political conditions in which the architect was working, so that it becomes a mirror of one of his specific and theoretical path, always in a state of becoming. Pagano understands architecture as a “servant of the human being”, subject to a “utilitarian slavery” since it is a clear, essential and “modest” answer to specific human needs, free from aprioristic aesthetic and formal choices. It is a rational architecture in sensu stricto; it constitutes a perfect synthesis between cause and effect and between function and form. The house needs to accommodate these principles because it is closely intertwined with human needs and intimately linked to a specific place, climatic conditions and technical and economical possibilities. Besides, differently from his public and common masterpieces such as the Palazzo Gualino, the Istituto di Fisica and the Università Commerciale Bocconi, the house projects are representative of a precise project will, which is expressed in a more authentic way, partially freed from political influences and dogmatic preoccupations and, therefore, far from the attempt to research a specific expressive language. I believe that the house project better represents that “ingenuity”, freshness and “sincerity” that Pagano identifies with the minor architecture, thereby revealing a more authentic expression of his understanding of a project. Therefore, the thesis, by tracing the theoretical research of Pagano through the analysis of some of his designed and built works, attempts to identify a specific methodological approach to Pagano’s project, which, developed through time, achieves a certain clarity in the 1930s. In fact, this methodological approach becomes more evident in his last projects, mainly regarding the house and the urban space. These reflect the attempt to respond to the new social needs and, at the same time, they also are an expression of a freer idea of built architecture, closely linked with the place and with the human being who dwells it. The three chosen projects (Villa Colli, La Casa a struttura d’acciaio and Villa Caraccio) make Pagano facing different places, different customers and different economic and technical conditions, which, given the author’s biography, correspond to important historical and political conditions. This is the reason why the projects become apparently distant works, both linguistically and conceptually, to the point that one can define them as ”eclectic”. However, I argue that this eclecticism is actually an added value to the architectural work of Pagano, steaming from the use of a method which, having as a basis the postulate of a rational architecture as essence and logic of building, finds specific variations depending on the multiple variables to be addressed by the project. This is the methodological heritage that Pagano learns from the tradition, especially that of the rural residential architecture, defined by Pagano as a “dictionary of the building logic of man”, as an “a-stylistic background”. For Pagano this traditional architecture is a clear expression of the relationships between a theme and its development, an architectural “fact” that is resolved with purely technical and utilitarian aims and with a spontaneous development far from any aprioristic theoretical principle. Architecture, therefore, cannot be an invention for Pagano and the personal contribution of each architect has to consider his/her close relationship with the specific historical context, place and new building methods. These are basic principles in the methodological approach that drives a great deal of his research and that also permits his thought to be modern. I argue that both ongoing and new collaborations with younger protagonists of the culture and architecture of the period are significant for the development of his methodology. These encounters represent the will to spread his own understanding of the “new architecture” as well as a way of self-renewal by confronting the self with new themes and realities and by learning from his collaborators. Thesis’ outline The thesis is divided in two principal parts, each articulated in four chapters attempting to offer a new reading of the theory and work of Pagano by emphasising the central themes of the research. The first chapter is an introduction to the thesis and to the theme of the rational house, as understood and developed in its typological and technical aspects by Pagano and by other protagonists of the Italian rationalism of the 1930s. Here the attention is on two different aspects defining, according to Pagano, the house project: on the one hand, the typological renewal, aimed at defining a “standard form” as a clear and essential answer to certain needs and variables of the project leading to different formal expressions. On the other, it focuses on the building, understood as a technique to “produce” architecture, where new technologies and new materials are not merely tools but also essential elements of the architectural work. In this way the villa becomes different from the theme of the common house or from that of the minimalist house, by using rules in the choice of material and in the techniques that are every time different depending on the theme under exploration and on the contingency of place. It is also visible the rigorous rationalism that distinguishes the author's appropriation of certain themes of rural architecture. The pages of “Casabella” and the events of the contemporary Triennali form the preliminary material for the writing of this chapter given that they are primary sources to individuate projects and writings produced by Pagano and contemporary architects on this theme. These writings and projects, when compared, reconstruct the evolution of the idea of the rational house and, specifically, of the personal research of Pagano. The second part regards the reading of three of Pagano’s projects of houses as a built verification of his theories. This section constitutes the central part of the thesis since it is aimed at detecting a specific methodological approach showing a theoretical and ideological evolution expressed in the vast edited literature. The three projects that have been chosen explore the theme of the house, looking at various research themes that the author proposes and that find continuity in the affirmation of a specific rationalism, focussed on concepts such as essentiality, utility, functionality and building honesty. These concepts guide the thought and the activities of Pagano, also reflecting a social and cultural period. The projects span from the theme of the villa moderna, Villa Colli, which, inspired by the architecture of North Europe, anticipates a specific rationalism of Pagano based on rigour, simplicity and essentiality, to the theme of the common house, Casa a struttura d’acciaio, la casa del domani, which ponders on the definition of new living spaces and, moreover, on new concepts of standardisation, economical efficiency and new materials responding to the changing needs of the modern society. Finally, the third project returns to the theme of the, Villa Caraccio, revisiting it with new perspectives. These perspectives find in the solution of the open plant, in the openness to nature and landscape and in the revisiting of materials and local building systems that idea of the freed house, which express clearly a new theoretical thought. Methodology It needs to be noted that due to the lack of an official Archive of Pagano’s work, the analysis of his work has been difficult and this explains the necessity to read the articles and the drawings published in the pages of «Casabella» and «Domus». As for the projects of Villa Colli and Casa a struttura d’acciaio, parts of the original drawings have been consulted. These drawings are not published and are kept in private archives of the collaborators of Pagano. The consultation of these documents has permitted the analysis of the cited works, which have been subject to a more complete reading following the different proposed solutions, which have permitted to understand the project path. The projects are analysed thought the method of comparison and critical reading which, specifically, means graphical elaborations and analytical schemes, mostly reconstructed on the basis of original projects but, where possible, also on a photographic investigation. The focus is on the project theme which, beginning with a specific living (dwelling) typology, finds variations because of the historico-political context in which Pagano is embedded and which partially shapes his research and theoretical thought, then translated in the built work. The analysis of the work follows, beginning, where possible, from a reconstruction of the evolution of the project as elaborated on the basis of the original documents and ending on an analysis of the constructive principles and composition. This second phase employs a methodology proposed by Pagano in his article Piante di ville, which, as expected, focuses on the plant as essential tool to identify the “true practical and poetic qualities of the construction”(Pagano, «Costruzioni-Casabella», 1940, p. 2). The reading of the project is integrated with the constructive analyses related to the technical aspects of the house which, in the case of Casa a struttura d’acciaio, play an important role in the project, while in Villa Colli and in Villa Caraccio are principally linked to the choice of materials for the construction of the different architectural elements. These are nonetheless key factors in the composition of the work. Future work could extend this reading to other house projects to deepen the research that could be completed with the consultation of Archival materials, which are missing at present. Finally, in the appendix I present a critical selection of the Pagano’s writings, which recall the themes discussed and embodied by the three projects. The texts have been selected among the articles published in Casabella and in other journals, completing the reading of the project work which cannot be detached from his theoretical thought. Moving from theory to project, we follow a path that brings us to define and deepen the central theme of the thesis: rational building as the principal feature of the architectural research of Pagano, which is paraphrased in multiple ways in his designed and built works.

Arti decorative: Bologna e Faenza tra Ottocento e Novecento

La ricerca approfondisce gli studi iniziati dalla dott.ssa Baldini in occasione della tesi di laurea e amplia le indagini critiche avviate per la mostra sull’Aemilia Ars (2001). La ricerca si è interessata alle aree di Bologna e di Faenza individuando le connessioni che tra Otto e Novecento intercorrono tra la cultura artistica locale e quella nazionale ed europea. Nasce infatti in questo periodo Aemilia Ars, uno dei più innovativi movimenti del contesto nazionale nel campo delle arti decorative. I membri del gruppo, raccoltisi intorno alla carismatica figura di Alfonso Rubbiani nei primi anni Ottanta, sono attratti da influenze nordeuropee e sin dall’inizio si mostrano orientati a seguire precetti ruskiniani e preraffaelliti. Molto importante in entrambe le città, per l’evoluzione dello scenario artistico e artigianale – in questi anni più che mai unite in un rapporto di strettissima correlazione – è l’apporto e il sostegno offerto dai salotti, dai circoli, dai caffè e dai cenacoli locali. Dal punto di vista dello stile, forme lineari con una marcata tendenza all’astrazione caratterizzano la produzione dei principali interpreti faentini e bolognesi dell’ultimo ventennio dell’Ottocento allineandoli con le ricerche dei loro contemporanei nel resto d’Europa. I settori produttivi che si sono indagati sono quelli della ceramica, dell’ebanisteria, dei ferri battuti, dell’oreficeria, delle arti tessili e dei cuoi. Gran parte di queste lavorazioni – attardatesi nella realizzazione di oggetti dalle forme di ispirazione seicentesca, certamente poco adatte alla produzione industriale – subiscono ora una decisa accelerazione verso forme più svelte che, adeguandosi alla possibilità di riproduzione seriale degli oggetti, si diffonderanno quasi capillarmente tra l’aristocrazia e la borghesia, faticando tuttavia a raggiungere le classi meno abbienti a causa degli elevati costi di produzione. Nell’ultima parte viene tracciato sinteticamente il quadro delle attività artistiche e artigianali faentine del periodo indicato, con una particolare attenzione all’opera delle personalità afferenti al Cenacolo baccariniano.

Dall'involucro all'invaso. Lo spazio a pianta centrale nell'opera architettonica di Adalberto Libera

An archetype selected over the centuries Adalberto Libera wrote little, showing more inclination to use the project as the only means of verification. This study uses a survey of the project for purely compositional space in relation to the reason that most other returns with continuity and consistency throughout his work. "The fruit of a type selected over centuries", in the words of Libera, is one of the most widely used and repeated spatial archetypes present in the history of architecture, given its nature as defined by a few consolidated elements and precisely defined with characters of geometric precision and absoluteness, the central space is provided, over the course of evolution of architecture, and its construction aspects as well as symbolic, for various uses, from historical period in which it was to coincide with sacred space for excellence, to others in which it lends itself to many different expressive possibilities of a more "secular". The central space was created on assumptions of a constructive character, and the same exact reason has determined the structural changes over the centuries, calling from time to time with advances in technology, the maximum extent possible and the different applications, which almost always have coincided with the reason for the monumental space. But it’s in the Roman world that the reason for the central space is defined from the start of a series of achievements that fix the character in perpetuity. The Pantheon was seen maximum results and, simultaneously, the archetype indispensable, to the point that it becomes difficult to sustain a discussion of the central space that excludes. But the reason the space station has complied, in ancient Rome, just as exemplary, monuments, public spaces or buildings with very different implications. The same Renaissance, on which Wittkower's proving itself once and for all, the nature and interpretation of sacred space station, and thus the symbolic significance of that invaded underlying interpretations related to Humanism, fixing the space-themed drawing it with the study and direct observation by the four-sixteenth-century masters, the ruins that in those years of renewed interest in the classical world, the first big pieces of excavation of ancient Rome brought to light with great surprise of all. Not a case, the choice to investigate the architectural work of Libera through the grounds of the central space. Investigating its projects and achievements, it turns out as the reason invoked particularly evident from the earliest to latest work, crossing-free period of the war which for many authors in different ways, the distinction between one stage and another, or the final miss. The theme and the occasion for Libera always distinct, it is precisely the key through which to investigate her work, to come to discover that the first-in this case the central plan-is the constant underlying all his work, and the second reason that the quota with or at the same time, we will return different each time and always the same Libera, formed on the major works remained from ancient times, and on this building method, means consciously, that the characters of architectural works, if valid, pass the time, and survive the use and function contingent. As for the facts by which to formalize it, they themselves are purely contingent, and therefore available to be transferred from one work to another, from one project to another, using also the loan. Using the same two words-at-issue and it becomes clear now how the theme of this study is the method of Libera and opportunity to the study of the central space in his work. But there is one aspect that, with respect to space a central plan evolves with the progress of the work of Libera on the archetype, and it is the reason behind all the way, just because an area built entirely on reason centric. It 'just the "center" of space that, ultimately, tells us the real progression and the knowledge that over the years has matured and changed in Libera. In the first phase, heavily laden with symbolic superstructure, even if used in a "bribe" from Free-always ill-disposed to sacrifice the idea of architecture to a phantom-center space is just the figure that identifies the icon represents space itself: the cross, the flame or the statue are different representations of the same idea of center built around an icon. The second part of the work of clearing the space station, changed the size of the orders but the demands of patronage, grows and expands the image space centric, celebratory nature that takes and becomes, in a different way, this same symbol . You see, one in all, as the project of "Civiltà Italiana" or symbolic arch are examples of this different attitude. And at the same point of view, you will understand how the two projects formulated on the reuse of the Mausoleum of Augustus is the key to its passage from first to second phase: the Ara Pacis in the second project, making itself the center of the composition "breaks" the pattern of symbolic figure in the center, because it is itself an architecture. And, in doing so, the transition takes place where the building itself-the central space-to become the center of that space that itself creates and determines, by extending the potential and the expressiveness of the enclosure (or cover) that defines the basin centered. In this second series of projects, which will be the apex and the point of "crisis" in the Palazzo dei Congressi all'E42 received and is no longer so, the symbol at the very geometry of space, but space itself and 'action' will be determined within this; action leading a movement, in the case of the Arco simbolico and the "Civiltà Italiana" or, more frequently, or celebration, as in the great Sala dei Recevimenti all’E42, which, in the first project proposal, is represented as a large area populated by people in suits, at a reception, in fact. In other words, in this second phase, the architecture is no longer a mere container, but it represents the shape of space, representing that which "contains". In the next step-determining the knowledge from which mature in their transition to post-war-is one step that radically changes the way centric space, although formally and compositionally Libera continues the work on the same elements, compounds and relationships in a different way . In this last phase Freedom, center, puts the man in human beings, in the two previous phases, and in a latent, were already at the center of the composition, even if relegated to the role of spectators in the first period, or of supporting actors in the second, now the heart of space. And it’s, as we shall see, the very form of being together in the form of "assembly", in its different shades (up to that sacred) to determine the shape of space, and how to relate the parts that combine to form it. The reconstruction of the birth, evolution and development of the central space of the ground in Libera, was born on the study of the monuments of ancient Rome, intersected on fifty years of recent history, honed on the constancy of a method and practice of a lifetime, becomes itself, Therefore, a project, employing the same mechanisms adopted by Libera; the decomposition and recomposition, research synthesis and unity of form, are in fact the structure of this research work. The road taken by Libera is a lesson in clarity and rationality, above all, and this work would uncover at least a fragment.

Dentro la struttura

Lo svolgimento della tesi segue la falsariga del discorso tenuto da Pier Luigi Nervi a Torino nel maggio 1961 al momento dell’inaugurazione del Palazzo del Lavoro. In quell’occasione egli illustra la concezione strutturale del suo edificio, realizzato attraverso l’accostamento di 16 elementi autoportanti e indipendenti (ciascuno costituito da un grande pilastro in cemento armato a sezione variabile - da cruciforme a circolare - e da una piastra metallica di copertura) che gli permettono di coprire uno spazio di 25.000 mq come richiesto dal bando di concorso. Nel descrivere le varie parti dell’edificio e le modalità con cui si sono susseguite le differenti lavorazioni (attraverso fasi di cantiere attentamente pianificate), Nervi omette un particolare interessante. Esaminando i disegni esecutivi dell’opera si rileva che all’interno di ogni pilastro è presente una cavità che permette di percorrerlo dalla base fino alla sommità. Ad una prima osservazione questi ‘cunicoli nascosti’ ricordano quelli ricavati nelle spesse murature delle cattedrali romaniche o gotiche, all’interno delle quali si trovano scale a chiocciola che collegano la cripta alla copertura o alle intercapedini del sottotetto. Come per le cattedrali del passato, anche nel Palazzo del Lavoro la creazione di uno spazio praticabile interno alla struttura risponde a più requisiti: funzionale (la manutenzione dei pluviali e delle coperture), costruttivo (la riduzione del peso proprio della struttura) ed economico (il risparmio del materiale). Nervi considera probabilmente questo dettaglio costruttivo un aspetto tecnico di minore importanza, appartenente cioè ad una dimensione ordinaria del proprio lavoro. Eppure, lo spazio ricavato all’interno del pilastro non coinvolge aspetti esclusivamente tecnici, ma sembra piuttosto nascere da una chiara visione progettuale che insegue un’idea di architettura, di unità, di organicità, di ‘servizio’ e di etica del mestiere. Dall’osservazione dell’edificio e della documentazione di progetto se ne ricava infatti una differente considerazione: lo scavo del pilastro non costituisce un aspetto secondario e, viste le implicazioni di carattere spaziale che introduce, merita di essere compreso e approfondito alla luce dell’intera opera di Nervi.

La ricostruzione dell'assetto topografico della VI regio augustea di Roma dal periodo repubblicano all'età tardoantica

La VI regio augustea di Roma rappresenta uno dei settori urbani maggiormente investiti dalle modifiche radicali compiute dall’uomo nel processo di urbanizzazione della città che ne hanno modificato profondamente la situazione altimetrica e la conformazione originaria. Questi notevoli cambiamenti ebbero origine sin dall’età antica, ma si intensificarono profondamente soprattutto nel periodo rinascimentale quando a partire da Pio IV e soprattutto con Sisto V, attivo in tante altre zone della città, si svilupparono numerose opere di rinnovamento urbanistico che incisero notevolmente sul volto e sulle caratteristiche della zona in esame. A partire dal Rinascimento fino ad arrivare ai grandi scavi della fine del 1800 tutto il quartiere incominciò a “popolarsi” di numerosi edifici di grande mole che andarono ad intaccare completamente le vestigia del periodo antico: la costruzione del Palazzo del Quirinale e dei vari palazzi nobiliari ma soprattutto la costruzione dei numerosi ministeri e della prima stazione Termini alla fine dell’800 comportarono numerosi sventramenti senza la produzione di una adeguata documentazione delle indagini di scavo. Questa ricerca intende ricostruire, in un’ottica diacronica, la topografia di uno dei quartieri centrali della Roma antica attraverso l’analisi dei principali fenomeni che contraddistinguono l’evoluzione del tessuto urbano sia per quanto riguarda le strutture pubbliche che in particolar modo quelle private. Infatti, il dato principale che emerge da questa ricerca è che questa regio si configura, a partire già dal periodo tardo-repubblicano, come un quartiere a vocazione prevalentemente residenziale, abitato soprattutto dall’alta aristocrazia appartenente alle più alte cariche dello Stato romano; oltre a domus ed insulae, sul Quirinale, vennero costruiti lungo il corso di tutta l’età repubblicana alcuni tra i più antichi templi della città che con la loro mole occuparono parte dello spazio collinare fino all’età tardoantica, rappresentando così una macroscopica e costante presenza nell’ingombro dello spazio edificato.

Emerging adulthoods. Percorsi giovanili di partecipazione e cittadinanza in prospettiva intergenerazionale

La tesi tematizza come proprio oggetto di indagine i percorsi di partecipazione politica e civica dei giovani nei contesti di transizione alla vita adulta, concentrandosi sull’influenza delle relazioni tra generazioni su tali espressioni di coinvolgimento. L’approfondimento empirico consiste in una ricerca qualitativa condotta presso il quartiere Navile di Bologna nel 2012. Basandosi sull’approccio metodologico della grounded theory, essa ha coinvolto un campione di giovani e un campione di adulti per loro significativi attraverso interviste semistrutturate. Dall’analisi emerge una rilevante disaffezione giovanile nei confronti della politica che, tuttavia, non traduce in un rifiuto del coinvolgimento, ma in una “partecipazione con riserva” espressa attraverso atteggiamenti tutt’altro che passivi nei confronti della politica formale - basati sulla logica della riforma, della resistenza o della ribellione - e mediante un forte investimento in attività partecipative non convenzionali (associazionismo e coinvolgimento). A fare da sfondo all’interesse partecipativo dei giovani si colloca una lettura negativa della propria condizione presente ed un conseguente conflitto intergenerazionale piuttosto manifesto, che si riflette sulle stesse modalità di attivazione. La politica, nelle sue espressioni più strettamente formali, viene interpretata come un ‘territorio adulto’, gestito secondo logiche che lasciano poco spazio ai giovani i quali, per tale ragione, scelgono di attivarsi secondo modalità alternative in cui il confronto con l’altro, quando presente, avviene prevalentemente tra pari o su basi avvertite come più paritarie. Il distanziamento dei giovani dalla politica formale riflette quindi una parallela presa di distanza dagli adulti, i quali risultano smarriti nello svolgimento delle loro funzioni di modello e di riconoscimento. La loro ambivalenza rispetto ai giovani - ossia il continuo oscillare tra il profondo pessimismo e il cieco ottimismo, tra la guida direttiva e la deresponsabilizzazione - si traduce in un riconoscimento parziale delle reali potenzialità ed esigenze dei giovani come cittadini ed adulti emergenti.

Città e architettura a Faenza nel Rinascimento. Progetti e strategie di rinnovamento urbano nell'età di Carlo II Manfredi (1468-77)

La tesi ha come oggetto il rinnovamento urbano che fu realizzato a Faenza per opera del suo signore Carlo II Manfredi tra il 1468 e il 1477, d’accordo con il fratello, il vescovo Federico. La prima opera realizzata da Carlo fu il portico a due livelli che dotò di una nuova facciata il suo palazzo di residenza, di origini medievali. Questa architettura sarebbe stata il preludio di un riordino generale della piazza principale della città, probabilmente allo scopo di ricreare un foro all’antica, come prescritto dai trattati di Vitruvio e di Alberti. L’aspetto originale del loggiato rinascimentale, desumibile da documentazione archivistica e iconografica, permette di attribuirlo con una certa probabilità a Giuliano da Maiano. Oltre alla piazza, Carlo riformò profondamente il tessuto urbano, demolendo molti portici lignei di origine medievale, rettificando le principali strade, completando la cerchia muraria. Federico Manfredi nel 1474 diede inizio alla fabbrica della Cattedrale, ricostruita dalle fondamenta su progetto dello stesso Giuliano da Maiano. L’architettura della chiesa ha uno stile largamente debitore all’architettura sacra di Brunelleschi, ma con significative differenze (come la navata definita da un’alternanza tra pilastri e colonne, o la copertura composta da volte a vela). L’abside della cattedrale, estranea al progetto maianesco, fu realizzata nel 1491-92 e mostra alcuni dettagli riconducibili alla coeva architettura di Bramante. A Faenza si realizza in un periodo di tempo brevissimo una profonda trasformazione del volto della città: loggiato, riforma della piazza, riordino delle strade, una nuova cattedrale, tutto contribuisce a dare lustro ai Manfredi e a fare di Faenza una città moderna e in cui si mettono in pratica, forse per la prima volta nell’Italia settentrionale, i dettami di Vitruvio e di Alberti.
