An architectural and structural manifestation of three successes, this project demonstrates the strength of a collective, the strengths of the circular economy and a practical application of the international Fab City movement. It was created thanks to the support of Icade Promotion, REI Habitat, Quartus and SUEZ. Following a call for projects published by the association Les Canaux: La Maison des Économies Solidaires et Innovantes, the Re-Store collective was selected to create this shade house in reused materials. The team had two months to complete the project, which aimed to animate the wharf during the summer months before being dismantled in September. The structure was delivered on time, 5 minutes before its inauguration, and remained intact until its dismantling. It was a real challenge against the clock.
With around 8.4 tonnes of recovered and reused wood, constituting 90% of the Ombrière, the project was a real success in terms of the use of recovered materials.
Sustainable development approach of the project owner
The challenge offered by the constraint of the Canals goes beyond the simple architectural project of a terrace.
This is a challenge for all those involved in construction, whether they are architects, engineers, companies or project managers: reducing the use of new materials and thus of our limited resources, and increase the reuse of what is considered waste.
The shade house commissioned by Les Canaux was intended to protect the organisation's activities from the summer sun, with notable requirements: the materials used had to be almost exclusively reused or recycled, and the project, from supply to design through manufacturing had 2 months to be set up.
The Re-Store collective took up these challenges by channeling the various expertise of its members, from design with WAO Architecture (coordination), R-Use, Studio Pourquoi Pas and EMA architecture, to production with Super Cube (lead company) and Remake. The project was therefore designed, produced and supplied by different actors. The collective was able to build the structure thanks to the generous space offered by the Orfèvrerie de Saint-Denis, where it was also able to store its materials, prototype and experiment with solutions. This third space was created by three partners: the real estate developer Quartus housed the collective; REI Habitat / REMAKE set up a carpentry workshop there, with machines and tools for traditional crafts, and WoMa managed the space while providing its community and digital skills.
The shape of the structure reflects the undulating movements of the canal with pieces of wood in sinuous shapes. Its roof, designed in reference to the hull of a boat, compliments these movements, and rises in its center to mark the entrance to the house of the Canals. This roof was designed as a wooden plank storage rack with wooden elements cut in the shape of a comb. This makes it possible to vary the inclination of the skylights which will land there, and to adapt to the dimensional heterogeneity of the sun screens. Indeed, the solar study and the parameterization of the model enabled the design of louvers whose orientation takes into account the course of the sun to maximize the shadows cast. The tubs play a double role: that of vegetating the terrace and of ballasting the structure. They were designed from reclaimed wood from the Arts Reserve and the Re-store stock. They were carried out by the collective with the help of Urban Vergers who carried out its revegetation.

Reasons for participating in the competition(s)
The project being ephemeral, it was completely dismantled.
Some of the elements are used for other projects such as certain bins which are now on the kiosks set up by the canals. The elements of Re-Store were returned to replenish the stocks of the collective at the Orfevrerie. The other roofing elements will be used for another project that Réavie will implement, thus offering a third life to these materials.
The structure is to be reassembled in the spring for a REI Habitat project to serve as the project house for the renovation of the Freedom Museum. None of the elements of the project were discarded.
