Abstarct: The Beginning of any design process requires a main factor that has the ability to guide the process in the right direction. The theorists of the “field of design” refers to this driving factor, which helps the designer to advanced his strategies at the beginning of the design process, as the initial generator or design concept. Designers have the ability to take advantage of several factors to choose a design concept among which factors related to the design site, factors related to the design topic, and factors related to the designer and his personal experience of design can be mentioned. The main topic of the current research is to understand the concept in architecture and how it relates to nature and used the results of those topics to design an educational-cultural center for children. In this regard, initially by conducting studies on the design process, the exact position of the concept in this path has been identified and how it is formed and its types have been investigated. In the following, by examining numerous examples of architectures forms in connection with the nature and their structural analysis, a comprehensive classification of all types of concepts that can be adapted from nature is presented. Finally by examining the characteristics of the child, the effect of the natural environment on him and the architectural components effective in improving the quality of the child’s space, the best and the most appropriate type of concept baxsed on nature has been selected. baxsed on the result of this research, the concept creates an integrated architecture that is harmonious in all areas. Also nature, due to having many positive features, is a very suitable source for adapting the desired concept. On the other hand, these characteristics of nature have positive effects on the child physically an psychologically and also his growth in various cognitive, emotional, social and value aspects. For this reason, in this research, an attempt has been made to design a coherent architecture in the heart of the natural space for children by using the concept adapted from nature.
