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.
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.
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.

Manuel Bello Marcano is an architect, lecturer at ENSA Saint-Etienne and sociologist of the imaginary at the Centre d’études pour l’actuel et le quotidien – CEAQ, Université Paris Descartes (Center for Current and Everyday Studies at Paris Descartes University). In his view, architecture is an act of aggregation designed to put the world in order: in this sense, he is interested in the political fictions mobilized to equip our thinking and, in this case, to build a “ togetherness ”. Follow his words and discover animality understood as community.

Since urine is an inexhaustible ecological fertilizer, why not use it instead of chemical fertilizers that are expensive to produce? Designer Louise Raguet suggests bringing back to the fields what has been collected there. Her research with the LEESU laboratory (École des Ponts) has led her to develop a unique project: urine separation in the future Saint-Vincent de Paul district of Paris.
Through animation, installation, sculpture and painting, Victor Cord’homme reveals the complexity and tireless workings of an urban system over which humans are losing control. He works on the autonomy of his installations and exhibitions, whose behavior varies according to the audience, invited to interact yet powerless to do so.
The growth in energy consumption and the obsolescence of our infrastructures suggest that by 2030, we’ll have a stock of 60,000 tonnes of end-of-life wind turbines per year. To absorb this material on an industrial scale, we need to invent new ways of producing, consuming and building. With this in mind, the La Paletière project aims to reuse turbine blades – composite materials with multiple properties – by turning them into roofing elements.

The challenges of air in architecture encompass a wide range of considerations that can affect the shape of a building, its degree of openness, the proportion of voids and solids, or the implementation of specific technical solutions. To reconcile seemingly contradictory requirements, such as the tension between energy efficiency and natural ventilation, architects and engineers are redoubling their inventiveness. Air, due to its invisibility, invites us to create an atmosphere and to consider buildings in terms of breathability.
Marie-Sarah Adenis is a designer and co-founder of PILI, a company that develops biocoloring agents using microorganisms: an alternative to their petrochemical production. But the heart of her job is to harness the image of “microbes” to overcome the limitations of our imaginations and inject a touch of onirism into the dusty scientific narrative inherited from Pasteur.
“ Restoring a building does not mean maintaining, repairing or remaking it, it means restoring it to a complete state that may never have existed at any given time, according to Viollet-Le-Duc. ”
“ Restoring a building does not mean maintaining, repairing or remaking it, it means restoring it to a complete state that may never have existed at any given time, according to Viollet-Le-Duc. ”
Viollet-le-Duc is famous for restoring the spire of Notre-Dame, which had been knocked down in 1792. In the course of this construction project, he reinvented the statues of the portals and the Kings’ Gallery, which had been decimated during the Revolution, because, in his words: “Restoring an edifice does not mean maintaining, repairing or remaking it, it means re-establishing it in a complete state that may never have existed at a given moment.” Bérénice Gaussuin, PhD in architecture, whose book Viollet-le-Duc : La forge d’une théorie de la restauration par la pratique (Viollet-le-Duc: Forging a theory of restoration through practice) has just been published (CNRS Éditions), takes a look at the approach of this extraordinary restorer.
Stripes, banners and colored filters are all part of the signature of renowned artist Daniel Buren. His work is rooted in the landscapes and architectures that welcome him and have become his open-air studio. In an exclusive interview with architect Philippe Chiambaretta, he talks about his attraction to transparency and his many collaborations.

Mathieu Arnoux, Professor at the University of Paris and Director of Studies at the EHESS, Isabelle Bensidoun, economist at the CEPII, Vincent Charlet, economist and founder of the Fabrique de l’Industrie and Liliana Doganova, sociologist and researcher at the CSI des Mines de Paris. This concluding conference looks at the social and economic dynamics associated with the exploitation of materials on a national and global scale. The war in Ukraine has revealed our dependence on our neighbours and reopened questions of sovereignty and self-sufficiency. France has been less affected by the Russian gas embargo than Germany, but the transition to renewable energies will not happen without the rare earths that we import mainly from China. The limits of globalisation seem to have been reached. What does this mean for our industry, our sectors and our economic policy? What role will the markets play, particularly the carbon market, in encouraging national and European materials?
With Marie Sarah Adenis, artist, Aurélie Mossé, research professor at ENSAD, and Simon Trancart, Head of Adaptative Laboratory Evolution at Ginkgo BioWorks. Wood is often referred to as a living material because it reacts to ambient humidity and develops a patina. However, when a tree is cut down to exploit its wood, it dies and ceases to photosynthesise. What other forms of living matter can we cultivate and grow to build and create, and what ethics should we apply? What does the future hold for organic materials that can regenerate rapidly or perhaps never die and continue to evolve as living matter? From the colourimetric properties of microbes to the use of algae to develop alternative chemical reactions to form cements and ceramics that emit less carbon, what possibilities does living matter offer us for rethinking creation?
With Mathieu Merlet Briand, artist, Benoit Roman, research director at the CNRS, Xavier Baris from Kairos and Michael Gaultois, Chief Scientific Officer of Fairmat. With the growing disenchantment of the public and designers alike with plastic, perceived as the offspring of the oil years and the symbol of a disposable world, the development of new materials that respond to contemporary challenges by proposing circular production schemes is long overdue. The Deeptech ecosystem is struggling to get off the ground in France, given the investment required. The government and the regions are encouraging research and entrepreneurial initiatives such as the FLOWER project to develop composites made from flax fibre, a plant widely grown in France. What are the neo-composites of tomorrow? What new mythologies do they invoke?
France has the 4th largest forest area in Europe, yet 40% of its timber is imported. At a time when Google’s London headquarters, designed in 2016 with a solid wood structure, has still not been delivered, and when the tallest wooden tower is due to be built in Tokyo in 2028, reaching a height of 100 metres, where does France stand in relation to wood? The RE2020, through the dynamic life cycle analysis, encourages the use of bio-sourced materials to promote the storage of biogenic carbon in buildings. The SNBC is explicitly banking on this sector to achieve its 2050 targets. However, the Paris Fire Brigade doctrine published in 2021 greatly complicates its use in architecture. How can these contradictions be overcome?
Although soil is used as a building material in many parts of the world, it has often been regarded as a waste product in France in recent decades, with little use being made of excavated soil. However, its thermal and hygrometric properties, its extremely low carbon footprint when used raw, its abundance and the natural variations in colour that it offers in every region make it a rich and inspiring material for today’s architects and designers. How can we adapt our building techniques to bring this material into line with contemporary requirements, and get rid of the vision of primitive housing that it still evokes for many people?
At its core, the campus embodies an enduring quest for an ideal. Its form is fraught with tensions inherited from a long history that remain relevant even as it adapts to contemporary challenges. Driven by a race to maximize their appeal, campuses are transforming into architectural showcases, competing with corporate headquarters in embodying new values and attracting top talent. Their structures and functions are evolving to meet the shifting needs of education and society. By embracing the archetypes of the agora and the garden—the original dichotomy of campuses—these bastions of knowledge are forming the contours of a new era in higher education.
Driven by a race for attractiveness, campuses are becoming architectural showcases, competing with corporate headquarters to embody new values and attract curious minds. The form and function of campuses are evolving to meet the changing needs of education, where tradition meets innovation in a drive for excellence and inclusivity. We are entering a new era of higher education!
Aurélie Mossé is a designer, researcher and head of the Soft Matters research group at the Ecole des Arts Décoratifs. Using micro-organisms, she is experimenting with the manufacture of innovative materials that are less costly in terms of fossil fuels or non-renewable resources. By producing calcite, bacteria could become allies in the creation of solid building materials.
A symbol of the industrial revolution, the rise of metal in construction accompanied the renewal of Paris under Haussmann. Its origins in blast furnaces is associated with a high carbon footprint. Yet it is still widely used in facades, and seems promising for circular economy, as it is easy to dismantle. But is this enough of an advantage? As part of the City Metabolism Chair supported by the Université Paris Sciences & Lettres.
Iris Handschin is an architect. In her final year thesis, DMC: Démocratie, matriarcale, citoyenne (DMC : Democracy, Matriarchy, Citizenship), she explores the relationship between sisterhood and architecture. How can we create a shared space of freedom and undo the hierarchical relationships at play in both private and public spaces? Exploring the possibilities of a feminist architecture inspired by the beguinages, Iris Handschin focuses on the rehabilitation of a former textile factory dating from the 1740s, outlining the contours of a truly democratic space.
La Vie à l’œuvre (Life in the Making), a collective of researchers in the natural sciences, humanities and social sciences, as well as artists, was set up at the Université Paris Sciences & Lettres in 2014 to explore interdisciplinary collective intelligence around the theme of the living. Functioning as an incubator of ideas, they explore the potential of living beings, particularly via experiments between art and science. A Stream 05 – New Intelligences article to discover!
Collective intelligence has become key to understanding and acting upon the complexity of the contemporary world. But how can the conditions for its advent be brought about? Originating in PSL, the “Life in the Making” collective, which brings together researchers in natural sciences, in the humanities, as well as artists, has been exploring this dialogue between intelligences around the theme of the living since 2014. By operating through a flexible framework, the collective has developed a praxis of interdisciplinary collective intelligence—all the while establishing new insights on life, in particular through experimentations between art and science.
The French underground and aerial landscape is made up of approximately 910,000 km of drinking water distribution pipes, and over 1.4 million km of power lines. Indispensable in our daily lives, they are nonetheless invisible and increasingly questioned in the light of ecological and technological challenges that are transforming our territories. But can’t these infrastructures be seen as a heritage to be maintained and cared for?
