It is project that participated as an artist in the ‘public design festival’ held in 2022. There was a request from curator “Everyday Practice (graphic design studio)” to design a structure symbolizing sustainable publicity. We proposed three ways for everyone to rise equally to a certain level. It is a work that creates a situation in which everyone can reach a specific height under fair conditions by using stairs and ramps. For example, the 1:12 ramp is designed for the elderly or disabled, and the 1:8 is designed for the other maybe with their dogs. Although each person has different physical conditions, we would like to talk about that the public design should respects differences and should propose appropriate resolution without excessive conviction.
