Four Elemennts (Water, Earth, Air and Fire), an Iranian Pattern for Urban Park Deign

Emptiness is a concept that appears in form and content. Beyond the meaning of being and not being .On the other hand Existential Identity depends on the dialectical relationship of that thing with its opposites. This study seeks to clarify the role of this concept in the vernacular architecture of Iran By understanding the concept of emptiness.

The research, by explaining the principles of empty concept, has investigated the quality of the realization of this concept in the form of fabric dimensions of Yazd's houses. The three pillars obtained from theoretical foundations were tested in five vernacular houses in Yazd. The research was conducted with qualitative study, and data collection tools: field observations, and the study of written resources.

The emergence of empty concept coincides with two elements or opposite qualities in such a way that the two opposites are interconnected without diminishing one another. Based on theoretical findings, the expression of the empty concept is conditional on the existence of three pillars: The first: the contradiction, the second: interaction, the third: balance and unity.

Based on research emptiness as a sublime concept is the result of the existence of opposing elements, their interaction and their unity. Vernacular architects with the perception of the necessity of the conjunction of the opposing couples and by recognizing the elements such as geometry, color, light, have caused the interaction of the opposites and their balance and they have come up with an empty concept in the form and fabric of these houses.
