Hangar 0 - read "zero", for zero waste, zero embodied energy, zero carbon, zero exclusion - is a project to convert a wasteland port in Le Havre into a citizen laboratory for ecological transition.
This project, winner of Réinventer la Seine, consists of the redevelopment of a former coffee dock, on the edge of a river basin to accommodate activities centered on the circular economy and urban agriculture. A shop, a restaurant and two workshops and offices have already been delivered. Eventually, this third place will also include an aquaponic greenhouse, shared workshops, a Fablab , coworking spaces, shared vegetable gardens and a permaculture garden.
Its primary purpose is to mobilize innovative solutions to improve the resilience of the territory of the city of Le Havre . These solutions make it possible to raise residents' awareness of responsible consumption by bringing them closer to circular economy players who experiment, produce and transmit within the very heart of Hangar 0.
This third place revolves around several pillars of the circular economy, mainly reuse, eco-design, extending the duration of use and the management of waste as resources. Hangar Zéro has therefore set itself the objective of reusing 90% of the construction materials used for the development of the 2500m² site .
Building users opinion
The occupants participate in the design and construction of the place. Their opinion can vary greatly depending on their degree of involvement.
What emerges most often is the feeling of tremendous civic energy, but also that everything takes too long! Former future occupants, less involved in the realization of the project, have given up to join faster projects!
If you had to do it again?
Based on our experience, we would move towards a higher re-employment rate. We have a feeling of failure when, lacking reused wood resources, or steel, we were forced to buy a new part, so as not to delay the work.

- First of all, the earth which, in addition to being biosourced and local, comes from an excavation on another site in Le Havre. It is used in both body render and finish render, the only difference is that it is sieved for finish render.
- Coffee parchment (which is the husk of a coffee bean) is used in the body filler. We find a lot of them in Le Havre because it is the first coffee importing port in France.
- Sawdust, waste from sawmills, is also used in the body coating.
- Marble powder is used in the finishing coat.
- Hair, a rot-proof and renewable material in large quantities (every week a hairdresser produces about 50 L of hair), is used in the coating, they make it possible to fiber it. It is a local resource from the hairdressing salon “#Le Salon” located a few hundred meters from Hangar Zero.
- The crushed cardboard comes from packaging cardboard (waste from Hangar 0), it is used in the finishing coating.
- Burlap coffee sacks that were used to carry coffee on boats were also used as a carrier for the body filler. These bags recall the history of the place because the Hangar was used to store coffee.

Reproductibility and Innovation
- Our storage capacity is exceeded! We are now sometimes forced to drop off materials at a Recycling Center, which is a failure for us! This stems from the initial desire to save everything from the dump, and the attraction for an integral approach, pushing us to store everything. Now our principle is to keep only what we have an immediate or planned need for.
- Taken by time, we do not write the processes enough to transmit them. We sometimes do it a posteriori, when it really seems necessary to us. A more systematic procedure should be required, leaving nothing in the dark. This may be done later, when the volume and urgency of the work will be less restrictive.
Reasons for participating in the competition(s)
Hangar Zero is a place dedicated to the circular economy. The work is carried out as much as possible with reused materials to serve as a pilot project. To reuse materials, we combine recycled materials (corks, paper, cardboard, plastic, etc.) and locally sourced and minimally processed organic/geo materials such as wood, straw and raw earth. We seek innovation in the use of these materials, in order to disseminate new low-tech practices.
Today, Hangar Zero opened a first phase of work, which will be followed by other phases, which will be delivered at the end of 2022 and all at the end of 2023.
