Urban environment :

The container house is the first stone of the Elisa eco-village, a sustainable neighborhood project located on the outskirts of the city of Sainte-Marie on Reunion Island. The district is in a rather rural environment, in the heights of the city.

Two pillars guide the design of this eco-village: circular economy and short circuit. The goal is to create a neighborhood of container houses for disadvantaged people (the houses will be less sophisticated than the one presented in this case study). Local craftsmen will be mobilized on the site. The "village" will also include an organic farming farm, an eco-market and various shops built in huts made of bamboo threads. Finally, a solar farm should cover all the consumption of the district, thus making it an autonomous site.

The project is ongoing, construction has started recently.

Construction and exploitation costs

• Renewable energy systems cost : 7 000,00 €
• Cost of studies : 1 500 €
• Total cost of the building : 97 500 €
Additional information on costs :

7000 corresponds to the installation of solar elements for swimming pool heating, gate and surveillance cameras.

Reuse : same function or different function

Batches concerned by reuse :
• Structural works

For each batch : Reused Materials / Products / Equipments :

Use of recycled containers for the structural work: structure of the house and swimming pool.

4 containers of 12 meters for the construction of the house and 1 container of 6 meters for the swimming pool.

Field of use and material origin :

These containers come from the Port of La Réunion and were used for the transport of goods. They are therefore reused.

Sustainable design

Reusable materials :

The container for the house

The containers used for the house (4 units) are placed on 12 concrete and iron piles of 1m20 (80cm buried and 40cm outside) connected by IPEs. A crane truck was used to transport the containers from the Port of Réunion to the site. The containers were then welded to these pilings to ensure their maintenance, even in the event of major climatic events.

The pool container

A smaller container is used as a swimming pool. For this, the earth was dug in the dimensions of the container which was then inserted. Concrete elements support it from below. It is then necessary to reinforce the whole, otherwise the container risks deforming and yielding under the pressure of the water.

Reversibility / Adaptibility :

The day side of the house was left without a roof, in order to be able to enlarge the house in the future by adding other containers. This would also make it possible to build a terrace with a patio above.

Environmental assessment

Impacts avoided : water, waste, CO2 :

Water savings compared to concrete, less waste in terms of scrap metal, bag of cement and transportation of materials.

Reproductibility and Innovation

The containers were installed and supplied, and the house was designed, by a company specializing in the reuse of containers in swimming pools. This company had just expanded their activity to the reuse of containers in houses when the owners passed by and talked about their housing project. This project is therefore one of the first customers.

The owners then sent the plan of the land, the company made a 3D plan and then visited the land to see if it was suitable. A crane truck then delivers the containers.

The process is therefore quite simple and replicable, provided that the terrain is suitable.

Economic assessment

• Total cost of reuse : 9 000 €
