This volume delves into the collaborative project conceived for the Japanese Culture House of Paris by two practices based respectively in Tokyo and Paris. Developed as a site-specific habitat, its prefabricated and easily assembled structures open new possibilities for adaptation. The project explores the deconstruction of boundaries between home and social spaces, and how these concepts are in flux today. Both offices engage with the idea that architecture is a social, cultural, and experimental activity that explores the conditions of our lives in a changing world. A key aspect is the possibility of reviving the forest industry in Japan and Europe as a sustainable resource.
