Abstract Nowadays, man is the medium of great issues, thus it's necessary to study private relationships that could be found in the environment created by architects and how they fit man and his needs to create more suitable architectural spaces. Architectural researches rarely spoke about void directly; their theories focused on the physical elements and structural motives of buildings regardless of the preexistence of void in architecture. An architect should design in such a way to create the void surrounding him in the first place, not the physical formulas that would hold formal meaning. Few information were dedicated to study architectural voids and their specifications in particular, wherein it is so wide and comprehensive field, especially when we take its gradual consequent scales in consideration. City voids are formed to fit city scale (level), residential voids are formed to fit neighborhood scale and private voids are formed to fit home scale. Thus, it's necessary to clear the importance of void and analyze it in order to conceive it fully as a fundamental base in architectural design process.
