Working with living matter

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.

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?

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? As part of the City Metabolism Chair supported by the Université Paris Sciences & Lettres.

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.

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.

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.

Representing the Invisible City

The trend towards smart cities reintroduces a functionalist vision of the city, generating ever-increasing amounts of data. But how can the parts of urbanity that cannot be reduced to quantified data to be optimized be considered? Larissa Fassler seeks to make visible what forms the urban experience through sensitive mapping that reveals an overlooked city.

The Architect as a Merchant of Signs

Architecture conveys multiple meanings. An artistic discipline that was initially an expression of culture, it now seems to be increasingly at the service of economic forces. Yet, architectural products are transformed into mere embodiments of their client’s brand image when they are cleverly diverted and made to carry a promotional message. In this game, the big names of architecture emerge as winners, but does this strategy advance architecture itself or does it make it nothing more than an element of prestige subservient to economic performance? Sebastian Redecke is a German architect, editor for the architecture review Bauwelt.
