Energy-intensive building

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.

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.
