Fabrique de l'Art

In a context of changing cultural practices that question the future of museums, the Centre Pompidou launched a competition for the creation of a new conservation center. This competition was won by the architectural firm PCA-STREAM under “La Fabrique de l'Art” (The Art Factory) project submission. Housing the collections of the Centre Pompidou and the Picasso Museum, it will offer a comprehensive collection and conservation facility leveraging an innovative approach whereby, under one building, there will be both a facility for cutting-edge research/conservation and a public engagement space. The project, which is set within a delightful park, will become a new central location for residents of the Île-de-France region.

The “Champs-Élysées — history & perspectives” study

The Champs‑Élysées, History & Perspectives exhibition presents the study conducted between 2018 and 2020 at the behest of the Comité Champs‑Élysées by PCA-STREAM in collaboration with some fifty researchers, historians, scientists, engineers, artists, and economic and cultural actors from France and abroad. It traces the development of “the most beautiful avenue in the world,” analyzes its current usages, and proposes a vision of its potential evolutions in response to the challenges this area of the city faces in the present day. The Champs-Élysées is becoming a collective space to experiment with the development of a sustainable, desirable and inclusive city by 2030 through focusing on four main strategic priorities: reducing the impact of urban mobilities, rethinking nature as an ecosystem, seeking new uses, and the use of data for measurement and regulation.

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.

Displaced villages, uprooted populations

Moussa Belkacem is a PhD candidate in architecture at the OCS (Observatory of the Suburban Condition) laboratory of the Paris-Est Architecture, Cities & Territories School. His work focuses on the displacement of villages in Europe between 1945 and 2045. He examines projects to relocate urban areas that are bound to be destroyed, and stresses the need to consider the links between demolition and reconstruction, in order to better accompany these uprootings.

360 is part of the dynamic revitalization of the Plateau district and the future prospect of a pacification of the ring road. The project rehabilitates three office buildings from the 1980s that no longer meet current needs and expectations. Its remarkable location and accessibility, at the head of the ring road, at the border of Vanves and Paris, invited an ambitious rehabilitation to develop comfortable, efficient and innovative spaces, while adapting the building to contemporary environmental issues.

What Leboncoin tells us about urban exodus

Alexandre Coulondre is a data and real estate market specialist and researcher at Lab’Urba (Gustave Eiffel University). To analyze the phenomena of urban exodus, he collaborated with Leboncoin, the french small ads platform, which provided him with the data needed to study local migration. A podcast to listen to, to question some of the much-mediatized theories according to which, in the wake of the pandemic, many city dwellers have left the metropolises!

Aéroville

PCA-STREAM designed and completed a commercial and leisure center destined to become a new urban centrality in the Roissy-Charles de Gaulle airport area. Aéroville is inspired by the travel imaginary and diverts the codes of the international flagship store. It is a public space that hybridizes the codes of the airport with those of mixed-use activities of an urban center. Built in less than four years of studies and construction, it was delivered to the client, Unibail-Rodamco, in October 2013.

At the roots of “Urban Metabolism”

The use of the living organism metaphor in the field of urban system studies dates far back and is continuously reconfigured as events play out. Here, Léone-Alix Mazaud, a CIFRE PhD student (PCA-STREAM/École des Mines de Paris), repositions the meaning of the “urban metabolism” as defined by our firm within the history of approaches on the subject matter in order to highlight its unique features.

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.

Strategies for Urban Sustainability

Urban density, though challenged by the pandemic, remains beneficial in mitigating sprawl. As urbanization nevertheless impacts the climate, the challenge, for Jeffrey Raven, lies in working on the actual shape and configuration of this density to make it sustainable and sound. Running counter to technological solutionism, this involves measures such as creating microclimates which provide ecosystem services following a holistic approach. He views the district as the proper spatial scale to operate at, due to its specific metabolism and because it is one of the most nimble scales to experiment at, through intermediate forms of governance. Architects gain a central role in coordinating synergies between the stakeholders involved, pragmatically understanding their interests, and, thanks to their skills in prototyping, offering a shareable narrative around “zero carbon” demonstration projects.

Inhabiting Urban Mobility

Inhabiting Urban Mobility

We are faced with the need to bring about a behavioral shift to support the ecological, urban, and economic transitions. Given that space influences behavior, Sonia Lavadinho calls for a “relational city” to kickstart the process. Like the city itself, mobility could be perceived as not only functional, but as something that can take on a new dimension, as events. Enriching the urban experience through a proliferation of micro-events and social interactions would then change our spatiotemporal relationship to the city and foster better social behavior.
