Ephemeral House is a minimalist house located in Kyoto, Japan, designed by NAAD. Ephemeral House is a renovation project of a 100-year-old wooden building located in the center of Kyoto, Japan. The client, who is in his twenties and lives alone, asked for a temporary dwelling. The intent in this project is not only to generate an appropriate atmosphere for living, but also to avoid hierarchical dichotomy between past and present, through that creating a space that has a rich sense of transience and festivity.
