Jean Prouv� and Pierre Jeanneret's BCC Demountable House is part of the series of projects initiated in 1939 that center on the construction principle of the axial portal frame, created by Prouv� in 1938. The several examples of this small wooden building that were produced between 1941 and 1943 (during extreme wartime conditions) emphasize the two men's rare ability to adapt to constrained circumstances.
