Think Build

Nestled in the heart of the Bièvre Valley, the HEC campus embodies the living archive of modern tensions between nature and knowledge, heritage and forward-thinking. In a world undergoing transition, the school chooses to revisit this exceptional environment and integrate it into a sustainable, inclusive, and ambitious strategy. PCA-STREAM proposes a project that is both contextual and transformative: restoring coherence to a fragmented domain, reactivating landscape and social continuities, and creating a new embodied centrality : the Campus Heart, to give form to the HEC of the 21st century. A place of learning in and with the landscape. A campus aligned with its time.

In the heart of Les Batignolles, PCA-STREAM is restructuring a former parking lot into a mixed-use complex of hotels, restaurants and offices. Based on the atypical and industrial dimension of the existing building, but also on the cultural and artisanal heritage of the neighborhood, the agency has chosen to infuse it with a spirit that emphasizes innovation and creativity. An emblematic central space physically and symbolically articulates the programs by offering cultural and event-based activities.

The renovation of this emblematic building in Nantes, the Tour Bretagne, is an opportunity to transform an obsolete symbol of the Trente Glorieuse era by adapting it to the contemporary challenges. PCA-STREAM and MAGNUM reinforce its elegance and slenderness by adding a mixed-use housing program, becoming the precursor of a new era for the city and metropolis.

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 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.

PCA-STREAM has won the competition for the extension of the Bobigny courthouse by designing a building with a balanced monumentality, reaffirming without excessive theatricality the sacredness of justice. The new courthouse will offer a functional and exemplary building, embodying the idea of a justice of care.

At the initiative of the Comité Grande-Armée, PCA-STREAM delivers "Grande-Armée 2030", a strategic vision for reintegrating the Avenue de la Grande-Armée into the urban dynamic of Paris's historic thoroughfare and adapting it to the challenges of the 21st century city.

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.

The Champs‑Élysées, History & Perspectives exhibition presents the study conducted between 2018 and 2020 at the behest of the Comité Champs‑Élysées by PCA-STREAM in collaboration with some fifty researchers, historians, scientists, engineers, artists, and economic and cultural actors from France and abroad. It traces the development of “the most beautiful avenue in the world,” analyzes its current usages, and proposes a vision of its potential evolutions in response to the challenges this area of the city faces in the present day. The Champs-Élysées is becoming a collective space to experiment with the development of a sustainable, desirable and inclusive city by 2030 through focusing on four main strategic priorities: reducing the impact of urban mobilities, rethinking nature as an ecosystem, seeking new uses, and the use of data for measurement and regulation.

The restructuring of the 175 boulevard Haussmann is the opportunity to become part of a resilient and innovative city, capable of renewing itself. PCA-STREAM is bringing together two separate buildings to create a coherent office complex, focused on well-being and collaborative working. A contemporary and emblematic elevation, in glass scales, practically and symbolically links the buildings and eras. The complex has been chosen as the headquarters of the Lazard bank.

Covivio, Hines France, and PCA-STREAM have come together to create the Stream Building, a manifesto building located at the heart of the new Clichy-Batignolles district that integrates almost fifteen years of research by Stream Lab into innovations addressing the key challenges facing the cities of tomorrow. Circular by design, the Stream Building is a relational and productive hub that will energize this new urban center within the Greater Paris area by concentrating all the activities associated with a vibrant urban life.

In collaboration with the Taller de Arquitectura, PCA-STREAM is rehabilitating Marché Saint-Honoré, Ricardo Boffil’s contemporary masterpiece, in order to adapt it to today’s new uses and environmental challenges, while staying true to its original avant-garde design.
