Energy-intensive building

The objective is to build 1 Tiny house (small movable wooden house), with the participation of the future user of this house, and with a maximum of materials resulting from reuse, available on the Emmaüs de Norges la ville site and on other other sites.

It is jointly supported by the following two partners :

  • ADEFO, which is an association under the 1901 law working in the field of reception, accommodation and support for people in great social difficulty ;
  • the EMMAUS De Norges la Ville community, which welcomes 130 companions on its site.

 

The context


Since March 2021, following a call for expressions of interest from DIHAL, Interministerial Directorate for Housing and Access to Housing, ADEFO has opened a housing and support service called « Grands Précaires » .

Following the regular observations of the SIAO 115 21, the SIAO social monitoring committee identified around twenty people known to all the players in accommodation and housing, more particularly in Dijon Métropole, experiencing difficult life paths, interspersed with breakups and unable to settle permanently in housing or even accommodation. The issues identified are those related to child welfare pathways, addiction, behavioral problems and being on the street for several years, despite the various proposals / effective orientations. These are the people who are directed to the Grands Précaires service. Some of them with a long journey on the street and wandering cannot immediately imagine living in a traditional habitat.

The accommodation offered when the Grands Précaires service opened, here called Machureau, was organized from two townhouses close to each other, made available by Dijon Métropole. They both have a garden. Depending on their particularities, the people received can be installed inside one of the houses, alone or in pairs, also in diffused housing (elsewhere) but also today for two of them in caravans installed in the gardens .

 

The goal


Caravans are damaged, their need is still relevant and this type of habitat is still suitable for a few people. The tiny intended for Machureau is made without toilets, in order to create a progressive airlock between the street and more traditional accommodation for the people received who will have to use the toilets of the houses. It is built so that it can later be moved to another site (transport on a truck bed, then placed on simple studs on the host site). It is equipped with a simple electrical installation (light points, power outlet, 1 electric heater which are powered by a connection to the existing room).

Building users opinion

Benoit took ownership of his future home very quickly as he took part in its construction.

If you had to do it again?

A second tiny is already planned, this time for a companion from the Emmaus community of Norges la ville, and with his participation. ADEFO is considering with Greater Dijon the provision of other sites that would allow the installation of other tinys made according to the same principle for other people waiting for housing.

Urban environment

Benoit's Tiny is installed on the Machureau site, made available to ADEFO by Le grand Dijon Métropole. These are two houses with an interior courtyard and a large garden

Benoit's tiny will be placed in the courtyard, near one of the houses and facing the garden.

This site is the subject of an urban planning project on the horizon of 1 to 2 years. This will require it to be moved to another site, also offered by Greater Dijon, and will allow ADEFO to continue its housing action for people in great difficulty.

    Framework and low floor: timber frame from used pallets 11 m² of low floor and 17m² of framework.

    Coverage: 17.5 m² of recovered steel bins.

    Facades: 40m² made up of frame uprights from dismantled pallets and fir planks.

    Exterior woodwork: 1 door and 3 PVC windows recovered from the demolition of a low-rent housing building.

    Flooring: 11m² of parquet from end of stock.

    Locksmithing - metalwork: manufacture of a trailer with 2 caravan axles from a scrapyard and the frame structure with profiles from the dismantling of a metal frame.

    Facades with wooden frame, frame and low floor, exterior cladding : wood from the dismantling of pallets and packing crates, recovered and packaged by the companions of Emmaus.

    Exterior woodwork: salvaged from the Emmaus site and from a demolition company in Champagnole, following the deconstruction of an HLM building.

    Flooring: end of stock offered by a trader at Emmaus.

    Locksmith metalwork: IPN bars recovered from the dismantling of a metal shed by Emmaus and 2 caravan axles recovered from a car scrapyard.

Sustainable design

    Wooden structure: from dismantled pallets and packing crates, free of any spikes or screws ;

    • for the walls, fir or Douglas fir uprights with a 50 x 90 section
    • for the low floor and the frame, sections of 80 x 100

    Exterior joinery: in PVC from the deconstruction of an HLM.

    Trailer: resulting from the recovery of a metal hangar frame and scrapped caravan axles. For information, a new trailer would have cost around €7,000 including tax.

    The interior layout of the tiny was not made with fixed furniture. This can allow a flexible and modifiable arrangement, according to the desire of the occupant. The furniture comes from the recovery carried out by the Emmaus community.

    The insulation of the lower floors, the wooden frame walls and the frame was made of hemp panels, 80% offered by the company Biofib. In the case of a future deconstruction of the tiny, this insulation can also be recovered.

Reproductibility and Innovation

    The project

    The project was born from the exchange between the 2 structures working daily for the housing of people in precarious situations (ADEFO and Emmaus) and the volunteer wood construction expert who has already built a tiny house.

    The principle of this small tiny, which can be moved later according to needs, whose construction could also encourage the participation of the future user and suddenly its reactivation and above all facilitate its appropriation and a projection towards an enthusiastic personal project, has achieved consensus. .

     

    Reuse

    The choice of reusing materials was obvious, given the daily work carried out by the companions of the Emmaus community, and of course in the concern of limiting its cost of realization and limiting the carbon impact.

     

    Swarming

    FR3 Bourgogne having heard of this achievement, made a first info report at the beginning of April, then a second longer report on the notion of commitment and working together. Their dissemination makes it possible to make known this action and its spin-off.

    The 2 partners plan to produce a short film, which will help to continue this outreach to social actors in all regions.

Economic assessment

  • 3 400
  • 65 %

Social economy

    ADEFO Dijon and the Emmaus community of Norges, the city on the Côte d'Or. The participation of Benoit for the whole of the construction and of Aurélien (for the electricity) was a source of a first return to activity, which could subsequently promote a process of integration through work.

Reasons for participating in the competition(s)

When circular economy and social and solidarity economy go hand in hand, it's a Tiny house built from reused materials, collected by the companions of the Emmaüs community of Norges la ville.

This Tiny is built with and for people in great precariousness and without fixed accommodation, today hosted by the Association Dijonnaise ADEFO .

The strength of this type of housing: it can be moved to where the housing need is.
