The demountable house, designed by Jean Prouvé after the second world war as a quick and cheap prefab to house citizens of Lorraine, France, is an architectural icon. However the needs of people today are different from 1944 when they really needed a roof over their heads; the original did not have internal kitchens or bathrooms.
According to a book on Jean Prouvé by Benedikt Huber from 1971:
At the liberation in 1944, the Minister of Reconstruction ordered eight hundred houses for the homeless in Lorraine and the Vosges.... Each assembly team, comprising four specialists, left the factory each morning with a truck loaded with all the components of one house and returned that night with the work complete and the house occupied.
Now architect Richard Rogers is bringing the design into the 21st century, to be used as a holiday home. According to Dezeen, Rogers had taken the original plans and added the modern conveniences to the outside, leaving the 6m x 6m (20' x 20') basic box pretty much the way it was originally designed. Here's what it looked like inside:
Rogers aimed to "preserve the integrity of the original as a single living space," so the new additions are housed in satellite structures and a series of "service trolleys". These modules can be added in various arrangements around the central structure.
The update includes removable insulating panels inside, air conditioning, a kitchen pod and an interesting bathroom pod where the three main fixtures are distributed around a central column. It has a composting toilet and a grey water management system. Big tanks and service modules are rolled under the floor.
