The heritage value of the Voltaire electrical substation is clear and unique within the urban fabric of Avenue Parmentier. Its largely glazed industrial façade and riveted iron post-and-beam structure are the two defining markers of its historic character. In approaching this existing fabric, our respectful stance consists of intervening without impacting the structural grid or the historic façade, promoting 100% reversible interventions.

The image currently projected by the building is that of its industrial past; our intention is to adapt it to its cultural transformation.

Urban densification is one of the key challenges facing Paris, making the construction of an extension an obvious choice. It will embody the building’s new identity. An irregular volume inscribed within the existing proportions of the façade will float above like a landscape. Illuminated at night, it will serve as a cultural landmark for the neighborhood.

Infusing nature into the project is one of the defining aspects of our proposal, both by stimulating the imagination through a rock-like sculptural form and by creating a lush planted setting on the terrace, acting as a buffer between old and new. This creates a green interlude not only within the building itself, but also along the mineral streetscape of Avenue Parmentier.

The vegetated terrace forms part of a network of new, unconventional spaces punctuating the project. The generously open lobby takes on the unexpected status of a covered public space ideal for hosting events and activities. Meanwhile, the extension’s façade is woven with balconies and walkways, making use of every square meter to foster a vibrant hub of cultural and social life.

We were named winners of the Réinventer Paris competition in 2016.
