L'Orée 85 is a place of life and experimentation dedicated to the meeting between the public and to societal and environmental transitions, through a sustainable restaurant-café-bar, an educational garden and a cultural program.
Winner of a call for occupation of the fluvial area launched by Voies Naviguables de France (VNF), the project was born in the old lock house No. 85, along the Rhône-Rhine canal, on the initiative of three friends: Lola Bertrand, Manon Cordier and Maxime Billmann. From the first reflections, a point of honor was made to develop all aspects of the project with the greatest respect for the principle of sustainability , in accordance with the personal values of the three founding members and the logic of social economy. and solidarity in which the cultural third place, now constituted as a SCIC, is deeply inscribed.
From a planning and construction point of view, the in-house team has made second-hand and re-use automatic. As a private group, it is their convictions that have led them to use reuse as a priority as sources of materials: conservation of existing elements and reuse in situ. For the other elements, they have systematically chosen biosourced.
The house, whose atmosphere mixes Greece and holidays by the sea, is entirely furnished using second-hand furniture unearthed by browsing the classified ads, garage sales and consignment sales in the region: from the shell chandelier, to the amphora through the toilet paper dispenser with fish motifs. When the materials are not reused, they are almost all bio-sourced : tiles, fabrics, solid oak parquet, seagrass, wood wool, cob, or even lime.
Key local partners in sustainable housing and the circular economy were integrated into the project from the outset. Together with the BOMA Les BOnnes MAtières circular economy design office, a major regional player in reuse in the construction sector , a diagnosis of needs was first carried out and updated throughout the project, then a on the sourcing and on its routing on site of a maximum of materials coming from deconstruction sites was carried out: railings of stairs of wooden building reused in fence, bench and shelves; a reused metal staircase; cellar trellises reused as cleats; double-glazed window panes from a building reused as glazed veranda roofs or even office doors reused to make a chicken coop. As for the Atelier NA, a collective of architects working for inclusive construction , it fed the operational dimension of the reuse/reuse of the project while helping to make many aspects of this site participatory. The construction of a reused summer bar from the wire netting deposited in situ, the manufacture of wood and wicker structures with rounded shapes to receive the cob then the lime and the manufacture of a reused chicken coop from doors, have allowed the inhabitants of Strasbourg to appropriate the space by participating in its sustainable construction.
Several companies and craftsmen also participated in fully integrating the suggested principles into their approach, more or less present in their basic values: the carpentry and eco-construction company Hylê carried out the carpentry work on the terrace and the veranda with exclusively local wood (Douglas fir from the Vosges); the company Technopieux prepared the foundations of the aforementioned construction elements from piles screwed into the ground, thus avoiding concrete foundations; the locksmith-metalwork company La Forgerie built the frames to receive the reuse glazing; and the low-tech construction association Lowarchitech accompanied us on the implementation of the wickerwork, cob and lime work sites.
Building users opinion
At the opening night on Saturday, May 14th, descriptions of the place and the energy that emanates from it varied between vacation home, campsite, Woodstock. So many terms that suggest a feeling of well-being!
Below are some testimonials and comments from different people about the project:
“The worksites allow you to meet people and the atmosphere is really cool. There is a real collaboration behind it and they do this with everyone and for everyone. There's a satisfying side to seeing the place now and imagining the end result. I can't wait to come back to the opening and to be able to tell myself that I've put a little piece of land here." - Charlie, volunteer on the participatory sites
“Thank you for your admirable commitment to bringing this beautiful place back to life! » - Pierre Jakubowicz, city councilor, vice-president of the Tourist Office of Strasbourg and its Region
“This is the type of project where there is heart and investment. It is a human approach carried by a team with which one can easily identify. The out-of-town side of the site, this in-between, is quite atypical as a location. It really makes me want to visit him. - Aurélien, volunteer on the participatory worksites
“You feel like you've escaped the city even though you're 10 minutes from the centre. - Christiane, visiting cyclist
" Tremendous ! Delighted with the prospect of being able to bond with people as diverse as they are unknown in this magical place. I imagine - perhaps a little too quickly - bicycles, canoes and great games of tarot to change the world… And then the day when we can swim back… what a party! - Anonymous comment on a press article (Rue89 Strasbourg)
"The way you view people in this place does a lot of good." - Danny, volunteer in the garden via the La Cloche network which fights against the exclusion of homeless people
If you had to do it again?
- The square glazing which had to be reassembled on frames to become front windows of the veranda could not be reused. This implementation required the installation of non-conventional frames, which would have delayed the site by more than 6 months, which was impossible on a 4-month site. - Double PVC window door: was planned to become the main access door to Orée 85. The technical characteristics of the product did not allow PRM access to the site. Indeed, the entry threshold would have been greater than 2 cm. The window door could therefore not be used on the site. - Exterior galvanized staircase: during the implementation of the staircase, we realized that the 2 stringers were not the same size, and that the fixing bolts of the stringers provided were not suitable. We therefore had to make a wooden connection to make up for the too short stringer, and to buy threaded rods adapted to the staircase. This caused an additional installation delay, but the schedule was nevertheless respected, and the staircase could be installed according to the rules of the art. > make a more precise statement upstream of the elements to be reused, before transport to the site > be flexible on the site, and plan for contingencies in the schedule

Reasons for participating in the competition(s)
Without being motivated by evolving legislation in the circular economy sector, nor seeking to be part of a marketing trend in the era of the social and solidarity economy, the Orée 85 team and its partners feel deeply driven by the principles of sustainability. Ecology, social and economy converge in everyone's fields and have naturally intersected on the habitat side.
By being invested in all the multiple aspects of the project for this social and cultural third place and by wanting to consider sustainable construction as a normality, the internal team came to forget the efforts it was making in that Sens. It was the BOMA collective that invited us to become aware of the legitimacy that we would have to participate in this competition: the quantity of second-hand furniture and materials, the quantity of reused materials and the many innovations in terms of reuse (roofing windows, wooden fence and furniture, chicken coop, summer bar, etc. have earned us an environmental record that is sufficiently exemplary to compete for the Circular Buildings Trophies 2022.
