Fabrique de l'Art

In a context of changing cultural practices that question the future of museums, the Centre Pompidou launched a competition for the creation of a new conservation center. This competition was won by the architectural firm PCA-STREAM under “La Fabrique de l'Art” (The Art Factory) project submission. Housing the collections of the Centre Pompidou and the Picasso Museum, it will offer a comprehensive collection and conservation facility leveraging an innovative approach whereby, under one building, there will be both a facility for cutting-edge research/conservation and a public engagement space. The project, which is set within a delightful park, will become a new central location for residents of the Île-de-France region.

La Source Vive

La Source Vive is a new concert hall dedicated to chamber music located in Évian. The result of a collaboration between architects Patrick Bouchain and Philippe Chiambaretta. Its conch-like form is the outcome of sensory experimentation and scientific analysis aimed at achieving exceptional acoustics while blending seamlessly into its scenic surroundings. The project is housed by the Évian Resort and embodies Aline Foriel-Destezet’s commitment to promoting music. Born of her desire to support the creation of an architectural complex featuring a unique concert hall in service of a major music project, La Source Vive will be located at the Mélèzes site, in the close vicinity of La Grange au Lac, another iconic music venue designed thirty years ago by Patrick Bouchain. Together, they will form an exceptional architectural complex dedicated to music—two complementary facilities within the same institution working together to provide a complete, open, and supportive musical experience.

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.

360

360 is part of the dynamic revitalization of the Plateau district and the future prospect of a pacification of the ring road. The project rehabilitates three office buildings from the 1980s that no longer meet current needs and expectations. Its remarkable location and accessibility, at the head of the ring road, at the border of Vanves and Paris, invited an ambitious rehabilitation to develop comfortable, efficient and innovative spaces, while adapting the building to contemporary environmental issues.
