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? With Christine Deleuze, Director of Carbon Strategy at the ONF, Christophe Aubertin, co-founder of the Studiolada collective, Anna Le Corno, artist (to be confirmed) and Clément Quineau, head of technical affairs at the UICB and Eñaut Jolimon de Haraneder, CEO of Alki.
Stream Voices: “The network is alive” — networks and those who maintain them
26 June 2024
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? A new article by Hadif Ait Sidi Hammou.

In the historic financial district of Paris, PCA-STREAM is rehabilitating BERGÈRE ❌ PARIS, a building emblematic of the major banking sites of the late 19th century. The ambition is to revitalise the serene, classical architecture of the complex, but also to enrich it with a variety of programmes that reintegrate it into Parisian life: from a safe building, BERGÈRE ❌ PARIS is becoming a complex that is open to users and local residents.
Stream Voices: Soil as an environment, property as an inhabiting capacity
19 June 2024
Elissa Al Saad is an architect and laureate of the 2023 Palladio Fellowships for her thesis on soil as an environment. By comparing different possible forms of land appropriation, she raises the issue of preserving land resources in relation to ownership. The aim is to think of property as a support for a way of inhabiting that considers land as a common good.

Aesthetic of structures
14 June 2024
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.

Although earth 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 earth. 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? With Emmanuelle Déchelette, founder of Déchelette Architecture, Lucie Ponard, designer, Thomas Gaudron from Société du Grand Paris and Jean-Claude Morel, director of research at ENTPE (in videoconference).

24 May 2024
A symbol of the industrial revolution, the rise of metal in construction, used for the halls of major railway stations, and in urban spaces, through public furniture, accompanied the renewal of Paris under Haussmann. Its origins in blast furnaces bind it to an imaginary carbon footprint, sometimes justifiably so, since the carbon footprint of aluminum can be multiplied by 10 depending on where it is produced. How can we rethink our production chain and exploit the recyclability of most metals? While metal is still widely used in facades, it is becoming rarer in structures. In terms of the circular economy, however, it’s a promising material because it’s easy to disassemble. Is this enough of an advantage? With Antonin Yuji Maeno, founder of Cutwork, Manon Leconte, founder of Maximum Architecture, Patrick Lepense, Product & Segment Lead Manager at ArcelorMittal and President of Construire Acier and Cyrille Terrolles, Director of Innovation at GHM Eclatec.

Never once has Sissel Tolaas, Norwegian artist, chemist, linguist and researcher, uttered the word “perfume”. For the past twenty-five years, she has been collecting, inventing and breathing new life into smells, refusing to be part of the world’s aseptisation. Through her olfactory installations, she invites us to sense reality, its geography and its temporality. Most recently, she has recreated the smell of Pompeii, between sensory experience and memory of the past.

What will Paris be like under 50°C ?
10 May 2024
Our dense, mineral-rich capital is ill-suited to the extreme heat we’ll increasingly have to cope with. So what adaptation strategies can we implement? This is what we asked to Alexandre Florentin, Paris councillor responsible for resilience and climate issues. He chaired the “Paris at 50 degrees” mission, which delivered its report a few months ago: what fields of action for architects and urban designers?

Justine Emard is a visual artist. Her installations use AI to understand the living, exploring the boundaries between organic life and artificial intelligence. Bee swarms, encephalographic recordings and prehistoric paintings become learning supports for algorithms that, contrary to dystopian imaginations, generate new supra-hyper-organisms.
