Stream Building

Covivio, Hines France, and PCA-STREAM have come together to create the Stream Building, a manifesto building located at the heart of the new Clichy-Batignolles district that integrates almost fifteen years of research by Stream Lab into innovations addressing the key challenges facing the cities of tomorrow. Circular by design, the Stream Building is a relational and productive hub that will energize this new urban center within the Greater Paris area by concentrating all the activities associated with a vibrant urban life.

The melody of the living

Frédérique Jiguet is an ornithologist and professor at the Muséum d’Histoire Naturelle in Paris. In particular, he leads the STOC program: Suivi Temporel des Oiseaux Communs (Temporal Monitoring of Common Birds), which aims to understand the impacts of global change and the consequences of human activities on birds. We met him in situ, capturing the conflict between nature’s songs and urban noise.

In the heart of the revitalized Porte Maillot district, PCA-STREAM revisits the Parisian modernist heritage and extends the city-nature dialogue. The agency’s intervention respects and enhances the architectural qualities of the original structure. On the north side, the façade grid is reinterpreted in a contemporary style inspired by its original rigorous layout. Designed as a balcony overlooking the Bois de Boulogne, it highlights the exceptional linear nature of the building with unobstructed views of the greater Parisian panorama.The new headquarters of Murex, the world leader in software for the financial markets, was designed above all to maximize interaction and collective intelligence, an essential function of a head office that has been reinforced by the health crisis. Spaces are streamlined and legible, and fluid circulation is ensured by a core of elevators and Chambord staircases on the first day. Employees meet and exchange ideas in a place conducive to informal dialogue.

The eco-acoustic landscape of La Défense

Landscape is not just a matter of shapes and colors. It also emanates from the sensitive perception of a sound environment, however urbanized it may be. This is what Sara el Samman defends in her diploma project, awarded by the Fédération Française du Paysage. Would La Défense be the same without the sound of heels on flagstones?

Root gardening

To understand the living, you need to understand the invisible. This is what Véronique Mure, a botanist specializing in Mediterranean landscapes, is convinced of. By focusing on the relationship that people have with plants, she raises awareness on the importance of soil and roots and invites us to take care of them, like gardeners.

Looking at the soils of the Greater Paris

Photographer Anne-Marie Filaire explores the transformations of the landscape. Since 2019, she has been documenting the sites accommodating the excavated soils from construction sites in the Grand Paris project, revealing the plastic and political dimensions of this “in-between” state of the landscape. Her work is currently be exhibited at the architecture and landscape biennale (BAP) in Versailles and the Hambourg Triennial of Photography.

Building for the living

Criticizing architecture’s anthropocentrism, Ariane Lourie Harrison expands on the concept of a post-human architecture, which she teaches at Yale. An interactive architecture thus arises, putting technology at the service of a “new nature” so that façades can provide refuge to birds and pollinators.

Rootless gardens

Pierre Kerrand is a nursery manager specializing in the cultivation of plants of the Tillandsia genus. These are specifically selected for better adaptation to our latitudes and to meet our needs. They produce colorful flowers and can withstand both drought and moisture, as well as variable temperatures. They require no maintenance and, most importantly, thrive without any need for soil and are very effective at remediating air pollution.

Urban metamorphosis

A specialist of the living, philosopher Emanuele Coccia imagines how architects could make the cohabitation between species possible without necessarily having to carry out an act of ecological repentance or abandoning modernity. A “building as a forest” and a city as a natural reserve are a few examples of the irruption of fantasy within the city.

The language of forests

The anthropologist and author of How Forests Think (University of California Press, 2013) recounts his Amazonian experience among the Runa people in order to convey to our Western minds the idea of a language that can go beyond words and symbols. A language that connects the beings of the forest, both human and non-human. A language that we seem to have forgotten…

Considering Separation Beyond Dualism

The environmental crisis and the realization of the Anthropocene have fundamentally altered the way we relate to nature. Dissenting with the idea that nature is “dying” and opting for the idea of a generalized hybridity, Virginie Maris advocates keeping a separation—which she distinguishes from dualism—between man and nature, as a radical otherness worthy of attention, care, and respect. This vision of nature as the “wild part of the world,” free from human intentionality, helps put into perspective renaturation and rewilding processes, but also criticizes the notion of ecosystem services, in particular due to their dimension of commodification of nature and their contingency on an ideology of economic growth.

In order to understand how this complex system operates, we shouldn’t be splitting the sciences off from one another. For this reason, Jérôme is involved in the innovative approach of creating interdisciplinary observatories.

Developing and Disseminating a New Ecosystemic Law

The questioning of the binary vision of the world proceeding from modernity, which set nature and culture apart, examines in great depth our relationship with the living and the place granted to it. If we are to overcome our anthropocentrism, how can we then assign a new status to nature in order to better preserve it? For Marine Calmet, this involves moving beyond our attitude of domination of the living and productivist logics of growth and to instead think in terms of commons and the protection of the living. With the forward-looking curriculum Wild Legal, she explores and imagines the creation of new legal tools based on concrete case studies, in particular around the concept of ecocide, to protect the environment and imagine types of governance that could help achieve a more harmonious articulation of the local and global scales.

Transforming the City into a Museum for Contemporary Nature

As we are reconsidering our place as humans within nature, philosopher Emanuele Coccia investigates the natural phenomenon of metamorphosis and develops it into a philosophical concept that enables us to think about ourselves as part of a single breath of life that passes from one life form to another. Opposed to a penitential vision of environmentalism, he disagrees with the idea that the living should be viewed as fundamentally subsumed in the issue of ecological balances, life being a perpetual metamorphosis, poles apart from any notion of equilibrium. He champions the idea of a transformation of cities into “museums of contemporary nature” in order to overcome the conventional nature—culture divide and reinstate an urban interspecies approach focusing on cohabitation between all life forms and biodiversity.

Animistic Intelligence: the In-Between Network of the Living and the Machine

Nature returns to the city, but can this new relationship with the living influence the very processes and materials of architecture? As early as the 1960s, the avant-gardes explored the ties between the intelligence of machines and that of the living, it is now possible to hybridize organic and synthetic materials, opening up an experimental field between biodesign and computer science, to create alternative biomaterials, as well as bio-inspired morphologies, in a symbiosis between the natural and artificial which is key to a more symbiotic relationship with our environment.

In Search of Nature-Based Solutions

Increasing the place of plants in cities plays a key role in mitigating the urban heat island effect, but trees must be addressed as a systemic issue, interfacing with the air, the ground, and water. For Frédéric Ségur, we must re-engage with the knowledge of urban forestry in order to regain our intelligence of trees and counter the mistaken assumptions on their life expectancy in urban settings. Beyond political declarations, the idea is to plant well rather than simply a lot, and to provide adequate conditions for them to develop—including space and living soil—and to take into account the ecotypes, but also to get the plant palette to change in relation to climate change.
