Watch the replay of the "STONE" conference

17 April 2024

The use of stone in construction declined during the 20th century. Today, its return is acclaimed for its qualities: inertia, durability, low-emission processing, local presence… with what techniques and applications in 2024? Introduction to the series by Elisabeth Bouchaud, materials physicist and playwright. With Cyril Pressacco, architect and co-founder of the Barrault Pressacco agency, Denis Macrez, artist, Ana Hedan, Director of Prescriptions at Rocamat and Paul Vergonjeanne, doctoral student in architecture.

175 Haussmann — Lazard

At 175 Haussmann, PCA-STREAM brought together two buildings to create a new cutting-edge office complex, completed by an emblematic contemporary extension, to house the headquarters of the Lazard bank. The interior design team created the public and reception areas, using hospitality codes and a combination of openness and confidentiality.

32-34 Marbeuf — Interiors

PCA-STREAM reinterprets Marbeuf, an emblematic Citroën garage from the 1930s, disfigured by successive transformations. The aim is to give it a new image and new uses by reinterpreting its original style, from its structure to the details of its fittings, translated by its interior design team.

PCA-STREAM Office

PCA-STREAM takes its inspiration from its research on new workspaces, which are gathered in the second issue of the Stream book-magazine, “After Office,” in order to design its premises in the Marais, on the site of a former printing house. Designed as an ecosystem that brings together a variety of spaces for the use of a large multidisciplinary team, this place is the spatial embodiment of PCA-STREAM as well as a manifesto of its innovative vision of the work space.

Sustainable Materialities in Construction

Sustainable Materialities in Construction

In France, the construction sector accounts for one third of the country’s CO2 emissions. Materials, which are partly responsible for this ratio, are extracted, transported, processed, poured or placed, dumped or incinerated… All these steps are opportunities to work on limiting impacts, involving architects, among other things, in deploying a new aesthetic.

Maximizing reuse, minimizing transformation

Maximum is a design studio that maximizes the value of waste; its material, its form and its engineering. Some materials are transformed in a semi-industrial process while others give birth to unique pieces, such as the glass walls of the Centre Pompidou caterpillar.

Cities, both a problem and a solution

Cities, both a problem and a solution

Cities, like asphalt jungles, are dense inhabited spaces. Yet this density also helps limiting urban sprawl. Jeffrey Raven is a professor at the New York Institute of Technology and an architect specializing in resilient urban design. He advocates for the positive aspects of urbanization and seeks to resolve urban heat island effects by exploring the form, function, materiality and vegetation of the urban fabric.

Is plastic getting a facelift?

The star of the stage of the recently concluded Design Week in Paris, plastic seems to have moved beyond the disdain it had been experiencing lately. Thanks to recycling, its environmental footprint is now better controlled, which has turned into a real selling point. But beyond the material itself, it is an entire production logic that should be “recycled” to extricate ourselves from the dogma of newness and disposability.

Geoglasswork: territories of materials

Lucile Viaud is a designer and “geoglass” artist. Working from salvaged materials, she crafts objects that carry within them the history of the territories from where the materials originate. Its snail or abalone shells, forgotten sands, and powdered seaweed are slices of fleeting time and result in objects that cannot be replicated.

Complexity, multiplicity, and adapatation within ecosystems

Contemporary architectural research is often fascinated by biological life but with an approach that goes beyond simple organic metaphors thanks to recent technological developments. Alisa Andrasek discusses the link between biology and her architectural practice, and her interest in the distribution of information in natural processes—a complexity that she tries to approach via big data. Her work in computational design is influenced by the convergence between information and materials, in an increasingly complex and open synthesis which enables it to go beyond the production of form and address the dynamic processes of matter itself. Alisa Andrasek is an architect, director and founder of the Biothing laboratory. She teaches at the Architectural Association of London.

Demystifying and Repoliticizing Urban Data

In the face of the promises of the prophets of artificial intelligence and the marketing of those major economic players promoting the smart city as a solution to urban ills, Jérôme Denis and David Pontille remind us of the irreducible materiality and fragility of cities. Demystifying what they perceive as a form of “neopositivism” of data, they point out that data doesn’t exist per se, and in fact must be generated and then maintained at a significant cost. As a result, data is never neutral and takes on a fundamentally political dimension. Understanding this framework leads them to promote a paradigm of maintenance and fragility, instead of the more common one of sustainability and resilience, when approaching urban realities.
