The site of the former Truffaut College was built between 1884 and 1887 under the direction of architect Prosper Perrin. A building with remarkable architecture, it has been entirely devoted to teaching since its opening in 1887. The establishment closed its doors in 2013 and has since been decommissioned. In this context, the Metropolis of Lyon, owner of the premises, wished to initiate the reconversion of this site, which should lead to the writing of a new page for this emblematic building, while extending its initial vocation in favour of the youth.
Linkcity Sud-Est, associated with SACVL as an investor, and its team of partners (Hirundi, Lyon BD, Les Petits Chaperons Rouges and AFEV), have won the call for tenders from the Metropolis of Lyon to transform the site, based on the designs of the architects BAMAA and ARCHIPAT who will bring this former school building back to life. The work will be carried out by teams from Bouygues Bâtiment Sud-Est. It's a real renaissance that was thought for the former Truffaut college, openning it up to the neighbourhood.
Several axes guided the creation of this project:
- A qualitative rehabilitation of a heritage building;
- A program aimed at young people to maintain the building's historical vocation;
- A place of life, open to the district.
The benefits of the project are varied:
- On the economic level: This will make it possible to generate economic activity on the site, while creating jobs, but also to increase the residential, commercial and tourist attractiveness.
- On the environmental level: The life of the building is extended and some of the materials already existing and still in good condition are valued.
- On the societal level: The project encourages the creation of a territorial identity around the place considered as a place of life and cultural activities. This requalification of common spaces makes it possible to respond to current aspirations and needs by promoting the creation of social ties.
The key figures of the project
In terms of accommodation
- A 100% social student residence: 65 studios and 4 flatshares;
- A hostel (youth hostel) with 45 rooms ranging from 2 to 18 beds for a total of 201 beds.
In terms of business premises
- A locavore bar-catering of 200 square meters offering seasonal products in a zero waste approach, proposed by Hirundi (creator of authentic hotels);
- Rooms intended for associative activities managed by the town hall of the 1ᵉʳ arrondissement of Lyon;
- A lively courtyard open to the public during the day;
- A private nursery with 20 cradles;
- A graphic college and the offices of the “Lyon BD organisation” association.
In terms of reuse
In situ:
- 15.3 tons of materials reused;
- 100% of the solid wood flooring was removed and reused;
- 30% of the period carpentry preserved.
Ex situ and reused by associations:
- 100% of the benches of the former chemistry laboratories;
- Electrical equipment (lights, panels, sockets);
- School development equipment (cabinets, pegs, blackboards...).
If you had to do it again?
Several brakes and difficulties encountered during the operation could be improved:
- Anticipation of deadlines: It took a little over a month to carry out the diagnosis, for the integration of the elements to be kept and reused in situ as well as for the identification of the buyers.
- Optimisation of the storage and logistics approach: The entrance porch to the site was tight and the storage area was limited.
- Optimisation of the process of finding buyers/depositors: The process of identifying buyers was long and the visit and recovery of materials took place at the same time as the preparations for the site.

On the site of the Truffaut secondary school, three modes of reuse have been identified:
About 40 types of materials were kept on site or taken up by reuse channels:
The buyers of the materials/equipment are:
All the materials that have been reused come from the Truffaut college, but have different final destinations, as can be seen in the table below:

Henri furniture:
Former school desks and an old chalk board were recovered during the clearing phase of the Truffaut college site by the Emmaüs workshops. This equipment was used in the manufacture, by apprentice craftsmen from Emmaüs, of a small modular storage unit called Henri. On February 1, 2022, Henri furniture entered the collections du mobilier national, an institution in charge of furnishing the high places of the French Republic.
Reconditioning actions for radiators and wooden floors:
The radiators have been cleaned (sludge removal) and repainted. As for the wooden floor, the hotel has kept it for decoration.

Reasons for participating in the competition(s)
Linkcity and its partners have been able to bring life back into the Truffaut secondary school in another form, while preserving the existing building belonging to Lyon's heritage. A strong approach has been taken on the project to promote the reuse of construction materials. An approach that is perfectly in line with the perspective of the Trophées Bâtiments Circulaires.
