Brief presentation of the company 100 Detours, upcycling
The company 100 Détours specializes in the design and manufacture of furniture and architectural devices for interiors and exteriors in wood exclusively from old exterior joinery . Born from the meeting of Benjamin Verger, carpenter, and Jérémie Koempgen, architect-designer, it now integrates Pierrick Soulard, eternal jack of all trades in mechanical production training. The solutions offered range from interior and exterior furniture (constitution of a range of products), glued-laminated trays, acoustic panels, trellises and sunshades, to micro-architecture: garden sheds, bicycles, playground.
100 Détours responds to individuals, businesses, prescribers and public orders.
Our means, our ambition
We seek to find a second life for the wood of old exterior joinery (doors and windows) which, once deposited, are mostly incinerated or buried in France. These woods, with excellent qualities of durability, resistance and aesthetics, actually allow many reuses. We are the second link in a chain following ESIAM, an association for the purpose of employment, which deals with the collection and dismantling of windows in the agglomeration of Bocage Bressuirais in Deux-Sèvres and we offer an outlet for this resource. Our current mission is to invent qualitative works, aesthetically and technically, then our ambition is to participate in the spread of this practice in France by localities and deposits. Indeed, for this project to make sense, many production units of reasonable size must be created in France as close as possible to the deposit which is present throughout the territory.
Honors received :
- Regional award for wood construction 2021 - Pays de la Loire - outdoor development section.
- Regional favorite prize at the Canopée challenge 2022 Nouvelle-Aquitaine.
- Stars and Professions Prize, Responsible category, CMA des Deux Sèvres.
Architectural note
The bike shelter is designed as a space that rhymes with nature . Its frame is made of upcycled glued laminated. The perforated cladding, as well as the bike racks are also made of wood from old exterior carpentry. We worked on the framework as a 3D assembly of small section parts. The optimization of the sections of the pieces, with the help of Vivier Structure Bois, allowed us to obtain this light design, slightly reminiscent of art nouveau and the structures of Hector Guimard's canopies.
Environmental approach
What better program than a bike shelter, the frugal mode of travel par excellence, to push our intervention limits a little further. Reuse and re-use are starting to make headlines on clothing, cladding, decking or interior linings. We wanted to go further and get down to the manufacture of outdoor glued-laminated wooden beams, using our resource of wood from outdoor joinery, and constitute the frame of this bicycle shelter .
Technical description of the layout
It is a bicycle shelter 6.50 m long by 2.91 m wide by 2.54 m high, capable of accommodating 6 bicycle racks (12 bicycles). It is modular, extendable by modules of 3 m. It consists of three porticoes supporting the half cantilevered roof. The posts are made up of 4 pieces of 40x40 mm, the webs of the lattice girders have sections varying between 40x80 mm to 40x140 mm. The bike racks are 70x200 mm in section. Everything is placed on custom-made galvanized steel plates. The cover is made of alveolar polycarbonate and an overlay of wooden slats.
Building users opinion
Customers have repeatedly expressed their satisfaction with the bike shelter. Below is the comment sent by the president of the company:
Post Anne Brochard:
Beautiful as a bike shelter
Exactly a year after we moved in, we finally have our bike shelter. Well deserved and hard sourced. Really.
After having studied more than a dozen solutions (how many bicycles, supplied with electricity or not, metal, plastic or metal .. metal ????????, types of attachment, etc.),
Adjusted the budget twice by complaining about the (sometimes crazy) amounts announced,
I came across 100 Détours… which didn’t have a bike shelter.
100 Détours is co-directed by Benjamin Verger and Jérémie Koempgen
Their thing? Design and manufacture indoor and outdoor furniture in upcycled wood (understand "from the recovery of outdoor joinery"), manufactured in their workshop in Deux-Sèvres.
And therefore the possibility of designing a bike shelter entirely in wood made locally by such good people.
Our beautiful bike shelter is their first bike shelter.
The first shelter in a long series, I can feel it!
Yes really it is very integrated into the space. Can't wait to see it every morning!
If you had to do it again?
Following this first copy of the bicycle shelter, a report sheet was drawn up, among the points mentioned, to be improved later:
- The polycarbonate plates will be replaced by stadip glass plates. A search for partnership is being studied with Articonnex on this subject, in order to use reusable lenses. A second thin green roof alternative is also being studied.
- Subsequently, the entire structure as well as the laths will be prefabricated so that they can be shipped, then installed by a moderately competent team.

Urban environment
The bike shelter, overlooking a landscaped parking space of the Etincelle RH company, is also located on the edge of a tree-lined green corridor.
The proximity of the shelter to these walking spaces requires the construction to use natural materials. The mixed wood cladding, in openwork facades but also in the over-roof establish a dialogue, a link, with the adjoining park.
The frame also participates in the play of shadows and light, from morning to evening.
Finally, an association: "les amis du Bois-Jo", educate children and adults about the local nature, just behind in St Herblain.
It is interesting that Paul Corbineau, who is the French expert in the recognition of wood species, who from time to time gives us advice on the recognition of wood species, is a facilitator.

Sustainable design
- Beyond reuse, the process seeks to keep the most massive pieces of wood possible. The design of the book is therefore partly dictated by the formats encountered. This approach aims to facilitate reuse or future reuse of wood elements or material.
- Galvanized steel plates can be sent for conventional recycling at the end of their life.
- Polycarbonate, although it does not seem optimal to us in the project, offers good recyclability, since it can be recycled several times.
- All assemblies are designed to be removable (unscrewable), the "torx" screw heads will allow a good grip of the tip at the end of its life.
- The constructive mode is modular: the gantries are of the same geometry, and it suffices to adjust complementary modules to enlarge the bicycle shelter, so as to be able to save an end gantry during the extension.
- Particular attention has been paid to protection against rain and water. Use classes 3 and 4 ensure good durability of the shelter, without the need for maintenance and treatment of the wood. The significant offsets of the roof, as well as the legs, complete its protection.

Reproductibility and Innovation
- The company L'étincelle RH discovers us on a press article and calls us to design and build a bicycle shelter with exemplary value.
- 100 Détours draws a sketch of the shelter and its frame.
- The contract is awarded, for a delivery at the end of 2021.
- 100 Détours teams up with Maxime Vivier (Vivier structure bois), in order to set up a simulation of glued laminated beams from overcycling and to produce a calculation.
- The wood being of excellent choice (in the log), we are then aware that it would be advantageous to make physical tests on the LMC beams. We then contacted HD wood, in the premises of the Ecole spéciale du Bois in Nantes, to make quotations for mechanical resistance tests of the beams.
- A default value, unfavorable (for maritime pine LMC), is taken for our calculation.
- The work of drawing the frame, taking into account the dimensional constraints of the calculation, and the resource of reuse, is refined by 100 Detours.
- Delivery of the bicycle shelter in Saint-Herblain.
- Anne Brochard (l'Etincelle RH) becomes president of the design school of Nantes.
- Visit of HD wood of the manufacturing workshops of 100 Détours, meeting with Sana Baklouti, Teacher-researcher in productive engineering.
- Presentation to Fibois Pays de la Loire of the approach 100 Détours, during a meeting around the layout and the reuse. The shelter is very well received by the industry and project managers.
- The bicycle shelter is a candidate for the National Wood Construction Award 2022 in the Outdoor Design category.
- 100 Détours wins the "coup de cœur" prize at the Canopée Challenge in the New Aquitaine region, which grants us a free membership to Xylofutur (to initiate, accompany, set up and coordinate innovative collective projects), which will accompany us for 1 year for our R&D procedures. We are thinking of using this collaboration to move forward on the issue of testing LMC beams, serving the bike shelter.
- We receive a request for a shelter and bike racks from a Breton company with a strong ecological commitment, a second one from a Parisian co-ownership. A company specializing in soft modes of transportation is prospecting us to see if we can produce 20 / 100 / 200 units.
- At the same time, we are making progress on the design of a machine (4 sides customized) allowing us to accelerate our first steps of transformation. The region seems capable of accompanying us on this necessary investment.

Reasons for participating in the competition(s)
What better program than a bike shelter, the frugal mode of travel par excellence, to push our intervention limits a little further. Reuse and re-use are starting to make headlines on clothing, cladding, decking or interior linings. We wanted to go further and tackle the manufacture of outdoor glued-laminated wooden beams, using our resource of wood from outdoor joinery, and constitute the frame of this bicycle shelter.
The candidacy for the Circular Buildings Trophies 2022 is an opportunity for us to highlight the interest of reusing wood from exterior joinery, in terms of carbon footprint, but also to show the mixed aesthetics as well as the quality of the atmosphere. and use, which is induced by the specific constraints of the material.
Finally, the shelter is designed in a modular way, in sections of 3 m, it can be duplicated industrially.
