This thesis discusses the following points in the process of reconsidering the old architecture that is becoming a major problem in recent years, as well as in finding ways to utilize it as a private place and public place in today’s architecture. First, through discussions on the thingness inherent in architecture as part of the process of separation from architecture, I have argued that a part of the architecture that already contains the value of things can have a lasting meaning, with Charles Jenkins and Nathan Silver’s aspect. Second, the capacity of these things has been discussed for a long time in art, and based on this, it is argued through Rafael Moneo’s view that such a discussion is necessary in architecture. The third also argues with Rafael Moneo’s view is that it is necessary to consider architecture as a thing together with its type and context.
