Within the Ivry Confluence development zone (ZAC), the rehabilitation of the former BHV Halls is a project that integrates the different histories and timeframes of the site. The agency is supporting the transformation of this former industrial building—an emblem of the past—into a lively and attractive third place. The project’s environmental ambitions, combined with the structural flexibility of the architecture, make it possible to anticipate future programmatic changes and evolving uses.
Initially intended for demolition, the former storage facility of the Parisian Bazar de l’Hôtel de Ville has ultimately been preserved. A witness to a certain industrial activity, this third place will reflect the programmatic and environmental ambitions of the Ivry-Port district. The heritage character of the hall is enhanced while developing a climate strategy that serves as a reference for the neighborhood. The ribbed reinforced-concrete vaults and trusses are therefore preserved and highlighted, while thermal insulation is provided by a secondary outer skin. Bio-based materials are used and material reuse is encouraged.
The program, both dense and open, fits within the structural envelope of the building while taking the existing grid into account. This meticulous technical analysis allows for significant flexibility for the current and future programming of the third place: from community spaces to individual or shared workspaces, from a multipurpose hall to business incubators, from shared kitchens to laboratories, and from technical rooms to service and storage areas.
The backbone of the project is a gallery street system—an arrangement favored by the agency—that connects the various programs, ensures their potential evolution, and accommodates all the ventilation networks of the third place. Beyond being a circulation space, the cross-building street, topped with a glass roof along its entire length, becomes a place for encounters. It extends the activity spaces and storefronts that line it, where the café counter is also located. The exhibition space is integrated into this lively and naturally lit gallery.
