“ Restoring a building does not mean maintaining, repairing or remaking it, it means restoring it to a complete state that may never have existed at any given time, according to Viollet-Le-Duc. ”


Viollet-le-Duc, an inspired vision of restoration

Viollet-le-Duc is famous for restoring the spire of Notre-Dame, which had been knocked down in 1792. In the course of this construction project, he reinvented the statues of the portals and the Kings’ Gallery, which had been decimated during the Revolution, because, in his words: “Restoring an edifice does not mean maintaining, repairing or remaking it, it means re-establishing it in a complete state that may never have existed at a given moment.” Bérénice Gaussuin, PhD in architecture, whose book Viollet-le-Duc : La forge d’une théorie de la restauration par la pratique (Viollet-le-Duc: Forging a theory of restoration through practice) has just been published (CNRS Éditions), takes a look at the approach of this extraordinary restorer.

15-25 Amiral Bruix

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.

BERGÈRE X PARIS

PCA-STREAM lends new impetus to a banking complex from the late nineteenth century, remarkable by its heritage value but closed on itself and poorly adapted to today’s modern requirements. Through a subdued intervention following a circular approach, the studio has augmented the building with new outdoor spaces, as well as programs and services that are largely porous to the vibrant city life within the district.

40 Legendre

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 "makers" spirit that emphasizes innovation and creativity. An emblematic central space physically and symbolically articulates the programs by offering cultural and event-based activities.
