For this project to renovate a slab pagoda of the "Olympiades" and its transformation into a district management and Brico-theque, the circular economy and the reuse of physical and spatial resources were at the heart of our architectural approach.
First of all, the simple rehabilitation of old buildings by definition questions the ability of existing structures and spaces to reinvent themselves in order to accommodate new uses. This building, originally built by the architect Michel Holley, has been in turn a restaurant, a tea room, and today a bricothèque (collaborative manufacturing workshop), ERP and a room for diverse associations. Thanks to the support of the RIVP, the Javelin project has also made it possible to put into practice the transitional programming of changing spaces, a real challenge for contemporary cities. Indeed, in the summer interstice between the end of studies and the start of construction work, the pagoda has been transformed into an ephemeral cultural space by hosting the works of two painters and sculptors.
Finally, the reuse of materials was at the center of architectural thinking from the first design phases. This reuse is deployed on site along three lines:
- Ex-situ reuse: a metal staircase was disassembled, packaged and reassembled on another site.
- In-situ reuse: the existing glazing of the building has become interior glass partitions.
- Out-sourced reuse: the cladding of the project is made with parquet slats from another site under deconstruction.

Urban environment
The project is located in the Olympiades district, Paris 13th, built in the mid-1970s by architect Michel Holley. It represents a rare example in Paris of Dalle town planning, driven by modern thinking. The "rue du Javelot", which gives its name to the project, is in fact never visible, located under the project and disappears into the slab. The district is also very particular within the capital in terms of its architectural diversity and the many modernist achievements it presents.
Despite their historical quality, large housing estates are often decried, in particular by the omnipresence of concrete and the loss of the human scale. The "rue du Javelot" renovation project thus seeks to contrast with this mineral urban context through the use of a visible bio-sourced material and the detail of a non-standard slatted cladding.

Reproductibility and Innovation
- Ephemeral and transitional programming:
In the interstice between the end of studies and the start of construction, the project site has become an ephemeral exhibition space. To do so, a temporary occupancy agreement was developed with the lawyers of the RIVP and signed with the two artists. In the context of dense cities such as Paris, we believe that this question of transitional programming should be generalized to renovation projects. - Facade insulating glass frames
The difficulty in using insulating glazing indoors was to know their structural performance and their rebate dimension. The control office required the presentation of a technical sheet to accept this reuse. Fortunately, by studying the glazing precisely and deciphering the glazing insert, we were able to identify the original supplier (RIOU GLASS) and obtain from them a composition document giving a technical sheet.
- Softwood parquet:
In the current normative context, it is often complex to implement reused materials without being able to qualify their technical performance. This is all the more true for the structural elements and those participating in the enclosure of the building. As part of the Javelin project, a long discussion took place with the Technical Controller to allow the use of an old parquet floor (without technical data sheet) as cladding for the openwork facade. Its use was made possible thanks to three arguments: it does not participate in the sealing of the building (and a UV-resistant rain barrier is put in place); its thickness is more than 20mm; it is largely protected (ratio greater than 1/2.5) thanks to roof overhangs. - Metal staircase:
The implementation of circular dynamics requires studying the regulatory, legal and administrative constraints. Thus, with the participation of RIVP lawyers, a donation agreement was drawn up so that the metal staircase could be transferred to individuals for EX Situ reassembly.
