AXA Matignon shortlisted for the 2025 Best of Year Awards
1 December 2025
The AXA Matignon project, designed by PCA-STREAM for AXA IM Alts, has been shortlisted for the 2025 Best of Year Awards, one of the most prestigious international distinctions in the fields of design and interior architecture. Organized by Interior Design Magazine, these awards celebrate the most innovative and outstanding projects worldwide each year. This nomination recognises the ambitious transformation of AXA’s headquarters in the heart of Paris’s 8ᵗʰ arrondissement, where PCA-STREAM combines heritage preservation, environmental performance, and user-centred design. The project stands out for its refined treatment of light, redesigned circulation, and the integration of contemporary workspaces within a historic structure — a subtle dialogue between legacy and modernity that defines the agency’s approach. Being named among the finalists of the Best of Year Awards highlights the project’s international resonance and underlines PCA-STREAM’s ability to deliver architecture that merges precision, innovation, and desirability.

Conference – Museums and the Ecological Transition Philippe Chiambaretta, Fondazione Luigi Rovati, Milan — 27 November 2025 Invited to speak during the Scenari futuri session of the symposium I Musei nella sostenibilità. Necessità e opportunità, Philippe Chiambaretta presented PCA-STREAM’s vision for transforming museums in the context of the climate emergency. Drawing on the agency’s research and on a precise assessment of the cultural sector’s environmental impacts, he recalled that museums are among the most complex buildings to decarbonize. Their energy consumption—largely driven by climate control, lighting, and visitor flows—calls for a rigorous architectural and methodological response. Philippe Chiambaretta structured his talk around three key priorities: Rethinking buildings to reduce their actual environmental footprint.Museums must integrate low-carbon strategies at every scale: materials, thermal inertia, differentiated façades, prefabrication, reuse, and optimized energy management. For the cultural sector, the ecological transition begins with architecture itself. Revisiting conservation standards.Established several decades ago, current climatic standards (temperature and humidity) lead to extremely high energy use. Their revision—already initiated by ICOM and the Bizot Group—opens the way to more contextual, less energy-intensive conservation practices that do not compromise the integrity of collections. Positioning museums as cultural drivers of the transition.Beyond technical exemplarity, museums play a crucial role in shaping new collective imaginaries. Through their programming, architecture, and relationship to their territories, they can become key actors in the cultural shift required by the ecological transition. Philippe illustrated these principles through the Centre Pompidou Francilien – Fabrique de l’Art, designed by PCA-STREAM as a model combining stringent museological requirements with constructive sobriety and a bioclimatic approach—from geological concrete to passive climate-control strategies. This intervention forms part of the agency’s broader commitment to imagining more responsible, more adaptable, and more desirable cultural institutions, aligned with today’s environmental challenges.

Colloquium “Cities, Life and Technology: Urban Worlds in the Making” of the Ville Métabolisme Chair
Chaire Ville Métabolisme
12 November 2025
The Ville Métabolisme Chair has reached a new milestone. Led by Université PSL and initiated by PCA-STREAM, the Chair explores the city as a living system, bringing together researchers, architects, engineers, urban planners and anthropologists around a shared ambition: opening up new ways of understanding, representing and transforming urban worlds. The colloquium “Cities, Life and Technology: Urban Worlds in the Making” marked a new step in this collective adventure: three days of discussions with international speakers from the Collège de France, the University of Cambridge, the University of Oxford, Mines Paris – PSL and other institutions. This edition gathered remarkable voices — Patrick Boucheron, Matthew Gandy, Maan Barua, Jonathan Rutherford, Victor Buchli… — all woven together by a common thread: approaching the city as a living milieu. On PCA-STREAM’s side, Pauline Detavernier, Director of Research and Innovation and lecturer at the École d’architecture Paris-Malaquais – PSL, spoke in the session “Mediations.” She presented her work on how to make moving bodies perceptible and meaningful in urban and architectural projects. Léone-Alix Mazaud, research and innovation officer at the agency, also shared her investigations into ways of quantifying, modelling and rendering biodiversity tangible within architectural design. These reflections directly nourish our THINK / BUILD approach at PCA-STREAM. The colloquium was a rich moment of exchange, reminding us of the importance of the Chair: creating a space where research, practice and design can truly speak to one another.
