Architect：Palissad Architectures

Location：34-40 Boulevard de Port-Royal, Paris, France

Project Year：2021

Category：Offices

This building from the early 20th century is a structuring element of the Gobelins district and is distingued by its height, its concrete structure and its classic brick façade. As building has undergone multiple technical additions, its heritage and architectural quality has faded. If the exterior envelope that rises on Boulevard Port Royal remains unchanged, it is in the heart of the plot that the project is carried out.

In order to give back all the nobility to the preserved volumes of the two monumental staircases, the existing elevators are removed.

The presence of a telephone exchange still in operation on the second floor and in the basement excludes any possibility of new crossings in the levels. From this constraint emerges the idea of creating new vertical and horizontal circulations necessary for the proper functioning of the building. New glass volumes connect the building on the courtyard to the building on the street, and serve each of the floors. Conceived as "transparent boxes", the glass elevators offer a panoramic journey through the project, with the impressive view of the Paris skyline as a final step. By taking birth in a patio in the ground, these volumes become the support of a climbing vegetation.
