We built this shop (for drink and eat) with reuse of a secondhand container of ISO Standard. The cost of the store is very low, but the necessary specification is satisfied. The exterior of the container is re-paint by special epoxy corrosion prevention paint and completed with paint of a urethane system. The interior of the building are insulated by an insulator of the plastic. The floor is completed by the coloring concrete on a underlay insulator. The height of the ceiling was restricted by the standard of the container.
But, in that condition, rather than, it was the space which calmed down.
