Abstract
The idea of nature is one of the main debates in social sciences since ecological problems are firstly discussed. Recently, theoricians in several majors claim a new geographical era named Anthropocene. It means there is no autonomous natural system left on Earth. In that perspective, the main idea behind sustainable architecture needs to be re-discussed. The aim of this article is to clarify the idea of nature in architecture before and after the new description of Anthropocene. To maintain this purpose, article uses modern avant-garde roots of architecture in the idea of nature with discussing the theoretical debates of Frank Lloyd Wright and Buckminster Fuller. The relationship between avant-garde architects' theories and designs could clarify the architectural point of view in the new possible Anthropocenic situation.
