New uses

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 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.

At emlyon’s upcoming Gerland campus, which welcomed its inaugural students in September 2024, we’ve arranged the buildings around a spacious interior street and a spectacular central hub—Cœur Battant, the “beating heart” of the campus—where daily activities and key school events will converge. Every element is designed to foster interaction, serendipity, and collective intelligence. The campus opens itself up to the city, as well as to businesses and events. It is fully aligned with the environmental dynamics of the Gerland District as well, with its extensive garden and commonsense approach to sustainability, exemplified by its uncomplicated and efficient facades adorned with terraces and inviting outdoor walkways.

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.

At the heart of the Stream Building, PCA-STREAM's flagship project, the agency's interior architecture department has created the Stream Café, a reception area with hybrid uses that symbolizes the involvement of the Stream research program in the design of this unique complex, winner of the first Réinventer Paris call for innovative urban projects.

ShAKe offers the Euralille district an atypical and convivial silhouette, with a spiraling planted promenade topped by a belvedere. PCA-STREAM is rethinking the office building, opening it up to the city and its residents, to adapt to the changing face of an increasingly open-plan working world. The form of the building-promenade is an invitation to live and share.

In the heart of the revitalized Porte Maillot district, PCA-STREAM revisits the Parisian modernist heritage and extends the city-nature dialogue. The agency’s intervention respects and enhances the architectural qualities of the original structure. On the north side, the façade grid is reinterpreted in a contemporary style inspired by its original rigorous layout. Designed as a balcony overlooking the Bois de Boulogne, it highlights the exceptional linear nature of the building with unobstructed views of the greater Parisian panorama.The new headquarters of Murex, the world leader in software for the financial markets, was designed above all to maximize interaction and collective intelligence, an essential function of a head office that has been reinforced by the health crisis. Spaces are streamlined and legible, and fluid circulation is ensured by a core of elevators and Chambord staircases on the first day. Employees meet and exchange ideas in a place conducive to informal dialogue.

#cloud.paris stems from PCA-STREAM’s research and Société Foncière Lyonnaise’s ambitions. In the time and age of the intangible economy, its inner city location and its versatility coincides with the aspirations of the creative classes and the employees of high value-added industries, which are turning away from the single-use business centers of the periphery. Following heavy restructuring, this urban campus was designed as a relational ecosystem where the collective experience stimulates innovation and productivity.

PCA-STREAM has designed an energy-positive office building in Issy-les-Moulineaux, a service sector cluster that is undergoing major transformation. We were driven to revisit the form of a tripod by the specific nature of the plot and our ambition for environmental excellence. This bold morphology opens the building on the city by freeing up green areas, and it optimizes the energy footprint whilst providing a functional work environment that is focused on improving the well-being of its users.

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.

PCA-STREAM's interior design department completed the architectural restructuring of a 1960s-era office complex with a tailor-made layout of offices and common areas for the lessee, a major luxury brand. Comfortable and functional, the project develops a high-end image through the quality of the materials, which are handcrafted.

True to its urban vision of a sustainable, desirable, and inclusive city, PCA-STREAM is involved in Café Joyeux’s vocational center for the rehabilitation of people with mental and cognitive disabilities on the Champs-Élysées. As part of this solidarity-based partnership, the studio has designed a pop-up venue on the “world’s most beautiful avenue”, showcasing its staff’s capacity to provide quality service. The interior space, which is adapted to the special needs of its staff, has a welcoming and colorful atmosphere, providing a warm and friendly venue. On the walls, Café Joyeux’s adventure is displayed, while the prep space is open to the public in order for all the staff to be made visible, as this is not just a place of meeting and interaction, but also an awareness-raising project.

As part of the Eurodisney development zone, PCA-STREAM is designing a mixed-use, open-plan tertiary campus, co-designed with its user, Crédit Agricole Brie-Picardie. It embodies the traditional values of this bank, its environmental, social and cultural commitments, but also its commitment to the uses of tomorrow.

PCA-STREAM designed and completed a commercial and leisure center destined to become a new urban centrality in the Roissy-Charles de Gaulle airport area. Aéroville is inspired by the travel imaginary and diverts the codes of the international flagship store. It is a public space that hybridizes the codes of the airport with those of mixed-use activities of an urban center. Built in less than four years of studies and construction, it was delivered to the client, Unibail-Rodamco, in October 2013.
