This paper aims to clarify the trajectory of the exploration of folk objects by the 20th century French architect and decorator Charlotte Perriand, and to identify the evolution of the subject found in her work. In Perriand’s case, from the 1930s to the 1960s, she studied farmhouses in the West and in Japan to study the scales and gestures of human space. What Perriand found there was not something universal, but rather the very possibility of a variety of gestures. In particular, her theme of mountain dwellings was a representative of this research.
