SUPERSTOCK – The Ephemeral City 2016 : Report.

SUPERSTOCK – The Ephemeral City 2016 : Report.
Building the city made to measure
For its 10th experimental architecture festival, Bellastock propose a great conception-construction site in the aim to prototype/foreshadow the public space of a mutating territory : the “De la Bergère” departmental park and the banks of the “Canal de l’Ourcq” in Bobigny. After a 15 collectives/groups residency coming from all over France, 220 participants have realized temporary installation that integrates the current territorial programming study. The festival was draw on a year of occupation of the Miko wasteland as a new experimental workshop/Laboratory for reusing materials and citizen/civic participation/involvement.
Territorial explorative research and diagnostic

Thematic roundtables

Every two weeks from november 2015 to june 2016, Bellastock has organized roundtables, fostering 30 people for the festival organization. Gathered around specific topics, the association volunteers contribute to implement this great collaborative project. That is how are organized working groups relying to : the wasteland layout and design, audience and public mobilization, material resource territorial diagnostic, energy self-sufficiency. This group of volunteers forms the core of the management team during the festival.

Lecture series

In march 2016, a lecture series leads to the intervention of many territorial stakeholders and specialist of themes that feed the project. The series fostered 9 speakers throughout 3 debate-lectures:

– Round #1: “Co-Evaluation” – reinventing the diagnostic to provide a made to measure city. With Séquano aménagement (Urban developer), Amélior (Ragman association), De l’Aire (Urbanist collective)

– Round #2: “Co-Conception” – Experimenting to generate identity. With Paysan urbain (urban farmers), Collectif ETC (Architect collective), Le 6B / Julien Beller – Artist residency.

– Round #3: “Co-Construction” – Horizontal governance and circular economy. With Patrick Bouchain (architect), TerritoriZ (Collaborative urban transitions advisor) and UTB

More than 500 people have taken part of this lecture series

Territorial exploration

Parallel to this, exploration walks and educational tours are organized to meet the territorial actors. It contributes to constitute a territory shared-diagnostic through several complementary methods : visiting social solidarity economy stakeholders in order to understand their good practice and upcoming challenge, participative promenade looking for edible plants, participative walks where the inhabitants are able to express freely their proposal and suggestion for the urban development and the public space design, or to play with “serious games” especially conceived to decrypt the current uses of the public space.

Miko wasteland construction site quarters

Ephemeral occupation of a wasteland

In autumn 2015, Bellastock is laureate of the call for expression of interest named “ephemeral occupation of wasteland” launched by the urban community of “Est-Ensemble” and the urban developer “Séquano aménagement” whose purpose is to boost the lands waiting for urban design along the Ourcq canal. Bellastock proposal is to experiment the construction and the animation of a building site camp, the construction site quarters dedicated to reusing material practice and audience participation, involvement and empowerment into the upcoming urban development project. Since march 2016, Bellastock has the key set of Miko wasteland in Bobigny. It is a former industrial land owned by the famous ice cream producer Miko who is nowadays waiting for the construction of a residential buiding in the frame of the joint development zone named “Ecocité”.

Manifesto building

To establish itself on the wasteland, Bellastock build the construction site quarter as a temporary manifesto building. From one hand, it is the result of collaborative design lead by the volunteers team during the roundtables with the methods developed by Bellastock. On the other hand the building is mostly made of reused material or by diverted components: downgraded maritime containers, industrial storage racks, concrete blocks drying boards and agricultural greenhouse as its roof. This building quickly became a iconic figure for the project and its territory.

Reused material storage

A large part of the wasteland layout is design to receive and store local salvaged material. Three types of deposit are identify : local industrial waste, materials gleaned in a rubbish dump due to a pilot operation led in partnership with Véolia, and finally materials coming from the demolition operations relying to the current urban development along the canal. This salvaged materials are stored into racks build by reusing materials, they support solar panels, making the demonstration of the energetic potential of a storage zone.

This materials are the main resources provided to Superville residency and Superstock collective construction site.

Superville meeting #2 – Architect collectives network

Superville meeting #2

 2013, under the impulse of Collectif ETC, Superville network is gathered for the first time, it brings together the main french collectives of architecture. In 2016, Bellastock offers to organise and foster the second edition of this network meeting. In addition to it, residencies has been settled for the collectives to make them conceive and build temporary installations in the surrounding public spaces. Indeed a first weekend dedicated to thematic roundtables, talks and debate co-organised with Collectif ETC and esPASces possibles has been followed by a week of residency to build together and provide performative actions.


The 2nd and 3rd of july, 45 european and french collectives are gathered at Miko wasteland to share their experiences about emerging good practices combining experimentation and citizen involvement strategy in the urban and architecture fields. 8 topics are discussed with more than 150 peoples splited into talks group :

“What legal framework for architect collectives?”; “Collectives and popular education : what convergence to empower the inhabitants ?” ; “Governance and project economy : how to sustain a collective structure ?” ; “Insurance and technical evaluation of our pratices” ; “Training and multidisciplinarity : which place for us into pedagogy ? » « Professional posture and activism : issues and friction » ; « how to invent new common framework ? »


From the 4th till the 10th of july, 15 collectives stayed at Miko wasteland in order to conceive and build public installations. It brings a first draft of solution for the inhabitant territorial expectations. This 15 collectives had receive specifications as well as a design brief drawn up in advance by Bellastock from the shared-diagnostic produced with the local audience. Salvaged materials and tools where available for all of them.

This residency program is the first work of its kind in France, it clearly contributes to write a new urban & architectural culture.


Superstock festival – Collective building site into public space

SUPERSTOCK – Collective building site

Following Superville residencies, the great Superstock building site started, gathering 220 participant from the 13th till the 17th of july. The main given objectives are the same than during the beforehand residencies : to conceive and build temporary urban furniture and instalations in the public space in order to experiment new uses along the canal and foreshadow the future urban design. This ephemeral city format is part of Bellastock research about the collaborative construction of our environment. The idea is to make new project methodologies emerge but also a new aesthetic as well as a better conception of our environment.

Pedagogic building site

The building site is organized as a pedagogic workshop where the participants are supervised professionals coming from the Superville network collectives as well as by Bellastock architects. The workshop contents brings the students to become designers, builders and mediator of their project. Within 5 days, about 30 installations have been created to stay all along the summertime and serve the inhabitant and users of the park and the canal banks. It is an outside school pedagogic format that allows participants to take part in a real territorial context during its mutation.

Cultural program

At the same time, Hydropathes collective ensured various and rich cultural programing that allow to attract larger audience and bring the public to discover this emerging spaces as well as the project created by the participants that reveal an identity and make them adopt the new uses. Movie-ball, concerts, performances, and DJ sets added to many activities linked with numerous artists, including local artists, Hydropathes have realized a cultural residency that serve the territorial urban development. More than 7000 people had the chance to appreciate this cultural scene during the 3 first weekend of july.
