As part of the documentary “PCA-STREAM: From research to action”, we interviewed Jean-Louis Cohen, architect, historian of Architecture and professor at the Collège de France.
He depicts a profession that is concerned about its place in the world today, and describes how architects are reinventing themselves in order to face the social, technical and environmental challenges of the 21st century.

A philosopher and senior lecturer at the National School of Architecture of Marseille, Matthieu Duperrex explores ‘sentinel landscapes’—polluted soils, engineered rivers, industrial port zones—from a decolonial, multidisciplinary perspective attentive to the various ways of narrating the damaged world we have inherited. He regards these sites both as places of warning and as spaces of knowledge.
Over the span of several months, students from GOBELINS Paris scouted La Défense, examining the iconic business district from the fresh perspective of urban metabolism. As part of a documentary workshop led by Pierre-Jérôme Jehel and Laetitia Guillemin (GOBELINS) and designed in partnership with researchers from the City-Metabolism Chair at PSL University, some thirty students explored this territory. They did so by treating it not as a mere backdrop but as a living organism, traversed by flows, tensions, and rhythms, using photography as a tool for revelation. Their projects, located at the crossroads of artistic creation and research, unveil an alternative reading of this mineral space, between invisible flows and underlying tensions. Both sensitive and rigorous, this inquiry is chronicled here by Corinne Feïss Jehel (EPHE-PSL), Pierre-Jérôme Jehel, and Émilie d’Orgeix (EPHE-PSL) as part of a research project conducted by the City-Metabolism Chair (which is financially supported by PCA-STREAM, Artelia, and Groupama Immobilier).
Read our discussion on the subject of generative AI with Raphaël Doan, a specialist in the sciences of Antiquity and author of the uchronia Si Rome n’avait pas chuté (If Rome hadn’t fallen), an essay imagining, with the help of AI, what might have happened if the Industrial Revolution had taken place under the Roman Empire. Through this experiment, fascinating possibilities for historical and archaeological research are outlined, as AI facilitates the processing of archives, the translation of lost languages and the deciphering of burnt texts.
L’agence PCA-STREAM dirigée par l’architecte Philippe Chiambaretta a signé en 2006 le projet de réhabilitation d’un immeuble tertiaire destiné à accueillir le tout nouveau Centre d’Art Contemporain de Kiyv. Le projet architectural s’est construit en parallèle du positionnement éditorial et de la constitution de la collection, en collaboration étroite avec le mécène du projet Viktor Pinchuk et le curateur Nicolas Bourriaud. Retour sur la genèse de ce projet ambitieux, destiné à ouvrir l’Ukraine sur le Monde.
Once a sanctuary for dreams and imagination, nighttime has now been relegated to the mere role of a utilitarian prelude to daytime. Nocturnal realms possess an alchemical power capable of transfiguring our perceptions. However, when viewed through the lens of urban uses, the night also exacerbates inequalities and raises questions about the possibility of achieving an urban night that is accessible to everyone. Exploring the range of possibilities associated with the night reveals it as a space-time where complex interactions are woven that could be revitalized through a chronotopic and inclusive architecture.
For Daniel Buren, architecture is an open-air studio. In an exclusive interview with architect Philippe Chiambaretta, he talks about his site-specific work, where art and architecture meet, just like the Nuages Colorés that cover the scales of the 175 Haussmann glass roof.
In urban planning and geography, the concept of metabolism is frequently discussed. This organicist metaphor likens a territory to a body, traversed by flows of materials and energy that link it to its environment. From a quantitative perspective, these flows can be measured over time and space to assess what a territory consumes, processes, and produces. However, a qualitative approach is equally crucial, examining the political and social trade-offs that shape urban metabolisms. With this in mind, we spoke with two researchers, Clément Dillenseger and Pierre Desvaux, who have explored the waste sector to analyze the socio-technical infrastructures that underpin metabolism and the imaginaries that shape its perception.
Andrew Freear runs the Rural Studio program at Auburn School of Architecture (USA). He believes that schools of architecture have an ethical responsibility to train citizen architects who are locally committed to concrete projects and experientially connected to contexts and places. To design an inclusive city, the Studio adopts an experimental field approach, combining analysis of the territory’s endemic problems, understanding of residents’ needs and new construction techniques.
