During World War II, the lack of material, particularly steel, became more and more prominent. Pierre Jeanneret and Jean Prouvé stretched their imaginations in search of a solution to limit the use of this material. Finally, a version made almost entirely of wood allowed for the creation of quality homes that were temporary and comfortable. The use of the axial portal frame offered great freedom to organize the 64 m2 interior space that was intended for a family of five people. Pierre Jeanneret designed a fluid, familial way of life around a fireplace generated by the visible central portal frame. Sliding doors separated the interior that stretched to a covered terrace outside.
For Pierre Jeanneret, as for Jean Prouvé, the obligation to adapt to extreme conditions was the opportunity to experiment with different resources and optimize the potential of a particular material. The aesthetically satisfying final product illustrates how the two creators responded perfectly to their circumstances in their incessant quests for authenticity and modernity.
