Machine system

Through animation, installation, sculpture and painting, Victor Cord’homme reveals the complexity and tireless workings of an urban system over which humans are losing control. He works on the autonomy of his installations and exhibitions, whose behavior varies according to the audience, invited to interact yet powerless to do so.

The Link

PCA-STREAM was tasked by Groupama to design an innovative tower that will renew the image of La Défense. Revisiting the model of the traditional tower, The Link is emblematic of the transformation of working practices and a new relation to the city. Its morphology in two wings connected to one another with platforms called “links” allows the tower to provide spaces that foster interactions and collective intelligence, and gives an unprecedented place to nature in a high-rise building.

Neo composites

With Mathieu Merlet Briand, artist, Benoit Roman, research director at the CNRS, Xavier Baris from Kairos and Michael Gaultois, Chief Scientific Officer of Fairmat. With the growing disenchantment of the public and designers alike with plastic, perceived as the offspring of the oil years and the symbol of a disposable world, the development of new materials that respond to contemporary challenges by proposing circular production schemes is long overdue. The Deeptech ecosystem is struggling to get off the ground in France, given the investment required. The government and the regions are encouraging research and entrepreneurial initiatives such as the FLOWER project to develop composites made from flax fibre, a plant widely grown in France. What are the neo-composites of tomorrow? What new mythologies do they invoke?

"The network is alive" — Networks and those who maintain them

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?

Restoration, transformation, maintenance

In this round-table discussion, the four researchers look at the issue of transition through the prism of the different notions of maintenance, transformation, repair and restoration. These concepts are reminiscent of the issues of destruction, reconstruction and rehabilitation in architecture.

“ Sewers are the mirror image of what happens on the surface. ”


What sewers say about us

Did you know that we have a lot to learn from sewers? Sewers contain numerous chemical indicators that provide information about the practices of people living above ground, such as the use of medicines and drugs, diet and the state of intestinal flora. By focusing on the city of Paris, the EGOUTS (sewers) research project, funded by the French National Research Agency (ANR), is seeking to shed light on public policy ‘through the dark side of the City of Light’.
