Nature, has always been a refuge for human beings and is considered as one of the basic pillars of human life.Since architecture also meets one of the most important human needs, namely habitation and home, it is considered as one of the basic human concerns since ancient times.The questions raised are what is the relationship between architecture and nature and to what extent has the relationship between these two main elements been effective in human life?Now that humanity is facing fundamental challenges in the field of natural resources, over-consumption, environmental pollution, destruction and waste of natural resources; To what extent can understanding therelationship between these two important principles help today's human beings to meet these challenges?Architecture with a naturalistic approach can be studied not only in terms of form and function, but also from the perspective of interaction with nature and learning the concept of sustainability.One of the most important and specific approaches in architecture is related to organic architecture, and therefore in this article we have tried to first analyze the concept of nature and architecture and their relationship to the principles and arguments of organic architecture.
