Beautiful like an encounter on the glass roof of colored clouds

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.

Micro lives and giga solutions

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.

Site-specific art, invading architecture

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. Discover Les Nuages Colorés, which cover the glass roof of 175 Haussmann with shimmering lights.

Tourist Office of Versailles

The new Versailles Tourist Office is intended to improve the reception of the millions of tourists to the château, while allowing them to discover the richness and variety of the city's cultural activities. In dialogue with a contemporary grove by landscape designer Nicolas Gilsoul, PCA-STREAM reinterprets the figure of the pavilion to offer a sober and minimal building, combining modernity and classicism, as a synthesis of what Versailles can offer the world.

Wood

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?

Metal

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?

Living Beings

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!

Stone

Discover the inaugural lecture of the “Alma Matter” series! In a world where the myth of abundance is collapsing, this series of lectures looks at what matter really has to offer. Actors, professions, economies, temporalities, geopolitics: how do contemporary issues of creation take shape through those of matter? Each talk focuses on a particular material, and brings together its stakeholders in a dialogue. The use of stone in construction declined during the twentieth century. Today, its return is acclaimed for its qualities: inertia, durability, low-emission processing, local presence… but what techniques and applications will be used in 2024?

Aesthetic of Structures

Aesthetic of Structures is a collective work published by the Architects-Engineers & Engineers-Architects association (AAIIA). Established agencies, young practitioners, researchers and students discuss a new relationship with structures, moving away from the Vitruvian principles of utility, solidity and beauty, towards an economy of materials, reversibility of use and the reuse of materials. Here we meet two of the book’s designers: architect-engineer Antoine Laugier and graphic designer Thanh-Phong Lê, who give us an insight into the book, as an object and as a structure.

Artificial Intelligence in the creation process

AI is a new form of intelligence whose development is stirring up concerns and dystopian fables. Far from replacing human intelligence, AIs are emerging as new tools to be trained, controlled and shaped to achieve the desired result. For the artist, photographer, architect, film-maker, musician or illustrator, AIs become an agent with which to collaborate, resulting in co-creation. Inaugural lecture of the “AI and Creation” series at the Stream Innovation Center.

Which architecture for the ephemeral?

Eric Mangion has been director since 2006, after managing the Frac Provence-Alpes-Côte d’Azur from 1993 to 2005. His research has long been focused on the artistic gesture of disappearance – in all its forms, from the alteration of the work to the disappearance of the artist. At the Villa Arson, he develops a program around ephemeral practices.  He develops here the link between his research topics – the disappearance, the ephemeral, in the art and more generally, in the culture – and the evolution of the architecture.

MOCO — Contemporary art center

A new institution for the arts in Montpellier, the MOCO brings together the Panacée and the École Nationale Supérieure des Beaux-Arts of Montpellier Méditerranée Métropole around the Montcalm Hotel. This headquarters for contemporary creation aims to federate the art scene in Southern France, and to break with cultural centralism, while at the same time avoiding a repetition of the “Bilbao” recipe of the spectacular object. It explores the possibilities for the transformation of the city through art in line with an organic model that rises to the contemporary challenges of regenerating historic cores and recycling existing architecture. The MoCo is in phase with a younger generation’s aspirations towards collective appropriation, co-production and the idea of making do with and together.

8 Penthièvre

PCA-STREAM is conducting the heavy restructuring of a real estate complex designed in the 1960s, tackling the obsolescence of an architecture that offers low-quality spaces in light of the new expectations of businesses. The façade is modernized and realigned on Rue de Penthièvre, and a new wing is formed at the end of the parcel, opening on a vast garden at the heart of the block. The intervention combines densification and the upgrading of workspaces, which are equipped with sunny, green terraces.

Experimenting with new modes of representation

Artists are major protagonists of the way our representations and narratives change over time, through image as well as fiction, which Frédérique Aït-Touati views as playing a fundamental role in the advancement of sciences and the construction of a collective imaginary. She is thus engaged, through her alternative cartographies and theatrical performances, in “landing” the gaze we turn towards the earth in order to highlight our belonging to Gaia. Besides her research on the developments of our ontological representations, she promotes, through SPEAP program, a pedagogy of experience, multidisciplinarity, and the dialogue between art and science.
