The transformation of the Caserne de Reuilly, supported by Paris Habitat, stems from the desire to rehabilitate and densify this site, by responding to the need to change an existing heritage, to seize its intrinsic qualities and to open up this place to residents of the neighborhood. Nearly 600 rental units (social, intermediate and undecided) as well as a nursery, artists' studios and shops are organized around a public garden open to the district.
By taking advantage of the main characteristics of this military architecture, a new urban form has emerged. The mineral square has become both a public garden and a place of passage, facilitating access between rue de Reuilly and boulevard Diderot, between housing and business premises. The transformation of the site, driven by re-use objectives, is accompanied by an imperative to preserve and rehabilitate the existing ones, instilling new uses within a reprogrammed military complex.
This project is the result of a long collaborative effort between Paris Habitat, h2o architectes (for the coordination and project management of public spaces), and 6 international teams of architects: Lin-A and Camille Salomon (lot A ), Anyoji-Beltrando (lot B), Charles-Henri Tachon (lot B1), NP2F – OFFICE (lot C), Mir (lots D and F) and Lacroix-Chessex (lot F).
Lot A (Lin-A and Camille Salomon) includes the rehabilitation of the left wing of the barracks and the construction of three new buildings for the creation of 91 social housing units, the Paris Habitat guards' lodge, a residence of 129 student housing units managed by the CROUS, accommodation for the CROUS caretaker, 1,230 m² of shops and local services, with the installation of roofs accessible and operated by the Quartier maraîcher association.
This lot, particularly dense and representative of the specificities specific to the overall operation carried out on the site of the Reuilly barracks, is used as a reference for this case study to deal with energy, environment and circular economy issues in housing spaces. Public spaces are also treated to show the possibilities of resorting to the reuse of materials in different contexts and at different scales.

The development of a public garden within the Reuilly barracks is part of the larger project to transform and densify the site. This new public space participates in the opening of the former military site towards the district, stretching to the feet of the housing in a continuity between landscape and architecture. By opening up the former 'place d'armes' to its environment, the urban and landscaping allows to regain permeability with the city, but also to revitalize the ground floors on the street, occupied by shops or business premises. The barracks becomes a place open to the neighborhood, visited and crossed by a large public. The mineral plots created on the three lanes bordering the plot open access to the central garden. Their mineral treatment in reused pavers incorporates grassed joints and planted or existing trees. Very wooded, the public garden continues this pavement to promote crossing routes. Its undulations on the ground create a shifting topography that multiplies the uses and puts the accommodation on the ground floor, equipped with planted valleys, at a distance. A continuum of grass, flowers and scents accommodates a diversity of uses and audiences. The programming of the garden has been refined with local residents and future residents, with tailor-made seats, games for children and vegetable garden areas.
Reuse : same function or different function
- Indoor joineries
- Lot inventory: 360 cast iron radiators (U)
- Reuse objective: 183 cast iron radiators (U)

Reproductibility and Innovation
- the question of durability arises in particular for the re-used radiators (although we took care to select, from the set of radiators deposited, those which did not present any significant pathologies);
- the reuse of lighting fixtures may be limited by their inadequacy to current electrical standards;
- remediation (asbestos and lead) can be costly (parquet strips, slates, gates, etc.)
- the transport and storage of materials require a specific organisation to avoid impacting on the different phases of the site. Some elements had to be moved according to the progress of the work, or others, such as the paving stones, were transported to the City of Paris' maintenance and supply centre in Bonneuil-sur-Marne.
- By batch sheets of reused materials allowing the monitoring and traceability of materials.
- Monitoring of project management and project management.
- On-site storage and flow management by companies responsible for reconditioning (workshop storage).

Reasons for participating in the competition(s)
All of the operations carried out for the rehabilitation of the former Reuilly barracks – creation of housing, business premises and development of public spaces – respond to the desire to offer a second life to the existing. By fitting into the plan drawn by the buildings erected in 1847, our project makes it possible to preserve a trace of successive urban developments, but also to reintegrate certain elements, materials and plants present on site - punctually adapted or transformed to serve new uses. Before reusing, we seek to preserve, to show, expose and keep the essence of a context invested with new meaning through reprogramming.
