| Abstract |
This study analyzes the inheritance and transformation of the free plan in Laurent Beaudouin’s library architecture, focusing on Henri Ciriani’s ‘L’espace 30×30’ studio design methodology. The free plan is understood not only as the structural liberation of walls, but also as an architectural principle that organizes spatial continuity, openness, and vertical relationships. The study first reviews the theoretical background of the free plan through Le Corbusier, Henri Ciriani, and Laurent Beaudouin. It then derives spatial elements from the 30×30 methodology and applies them to five library projects: Poitiers Mediatheque, Proudhon University Library in Besancon, Lucien Febvre University Library in Belfort, Le Mans University Library, and Brest University Library. The cases are analyzed in terms of building proportion, hall space, reading space, facade, skylight, and upper daylighting. The analysis shows that Beaudouin’s libraries continuously refer to the square order, central hall, void, ramp, and upper daylighting of the 30×30 methodology. However, these elements are not repeated as fixed forms. They are transformed according to site conditions, program scale, structure, and lighting strategies. In particular, the hall becomes an experiential space where movement, light, color, and object-like elements are integrated, while facades and skylights function as devices that filter, reflect, and diffuse light. In conclusion, the 30×30 design methodology in Beaudouin’s library architecture operates as a spatial principle reconstructed within real architectural conditions. His libraries demonstrate the contemporary potential of the free plan by transforming it into a sensory and experiential spatial language. |
