The project ‘Floating Structure’ deals with various tangible and intangible structures like environment, philosophy and politics of our society. Our goal is to re-think about these ‘structures’ which include not only infrastructure which is a prerequisite to urbanism but also the systems that have appeared after the modernist era and various structural elements that lie within our society. In this project, by re-thinking about these ‘structures’, we imagine a new type of structures that would appear in the near future. We focus on the substructure of cities which continue to expand vertically and how it would change our everyday life, landscape and senses. We also think about physical structures evolving from two dimensions into three dimensions as well as fluid structures, new connections and changes in bases in relation to invisible dimensions, the relativity to substructure and temporality.
