The concept which might have been unseen in many cases of today world’s architecture, but this carelessness has been developed until we can see its impact on conversion of the word “UNSEEN” to the word “LOST”. Space…? Lost…? First it is better to perceive the meaning of space and after that it is more interesting to know what the “Lost Space” means. One and maybe the most essential duty of any architect is the creation of space. But, what is the definition of “SPACE”? Assuming architecture presents the issue of space, having in mind the present time’s notions as well as being responsible for the projects prospective and demands, taking into account what the space accepts and how it happens, will bring us to more qualitative aspects of space. The essential elements of architectural design consist of two factors “Mass and Space”. The essence of design is the interaction between these two factors. The awareness of space is much more than a mental activity. This awareness occupies all domains of our senses and feelings, which needs a vast presence of essence to find a perfect response. In fact, any surrounded space, or better said, a building as a small member of the city, has to be in total harmony and solidarity with the whole city and the adjacent areas. Lack of attention to these criterions, qualitative policies and aesthetic parameters had led to our characterless current urban images. The space which is the basics for nowadays cities and urban architecture had lost its inner spirit; chiefly, it is a blind and decayed space without any organic communication with important capabilities of human being. Lack of various qualitative surfaces and volumes in space is simply the reduction of space to the quantitative aspect of humans. This happened while the current human being had broken down the priority of tradition due to its limitations and managed to get into the pathway of the modern world with a joyous approach. Another important issue in creating space is memory which is used as an essential factor in space formation and is dependent on the political, social and economic fluctuations further than functional operations. With growth of urbanism and the massive movement of the city toward modernism, an avoidable discussion, is the creation of space as well as its influence on the creation of place. In other words, what we understand from our environment and our recognition and perception of that space, is quite a different category of the massive shape through the surrounding walls. The important issue that emerges is the spatial experience and the massive function of space which makes its identity. In this research by utilizing both field research and library researches, the above discussion is complied and studied. We try to work with creating dynamics and shaping spaces with modern architecture through identifying the relation between architecture and urbanism in the middle of our cities. Also, this is actually an effort through identifying dynamic spaces in the middle of unidentified ones, and at the end donates them once again to the cities. On the procedure of this study, classified lost spaces are obtained and finally tried to design a space with the capability of responding to the primary demands of the contemporary society and also the future demands which are hardly to foresee;, a space for an interactive sensibility and responsibility not dictating an idea or a Manuscript Received on June 2014.

INTRODUCTION Definition of the word “Progektum” in Latin is to control rigidly, or conversion of a material from its initial shape to another which contains the concept of innovation and creation. In fact, the human being is to respond to his demands in any project. Therefore, despite of having a mental environment he creates another environment which contains architecture and is his own creation. Manmade environments have got different surfaces and the culture of any society is a function of manmade environments. Preserving and upgrading a society and responsibility for its demands such as subsistence, comfort, health… is a variable level of culture from manmade phenomena’s during the history. Therefore, quality of life in a civilization is the function of its cultural level [1]. Using different variable surfaces as a positive point in creating an art piece, has to be shown obviously with emphasis on the process of heightening and landing from a surface to another. This matters not only in planning, but ornamentally has to be seen with proportions to have a building which is acceptable both from the urban and psychological view [2]. In fact, any surrounded space or in other words, the building as a small member of the city, has to be in a total harmony and solidarity with the whole city and the adjacent areas. Lack of attention to these criterions, qualitative policies and aesthetic parameters had led to our characterless current urban images [3]. The space which is the pattern for nowadays cities and urban architecture had lost its inner spirit; chiefly, it is a blind and decayed space without any organic communication with important capabilities of human being. Lack of various qualitative surfaces and volumes in space is simply the reduction of space to quantitative aspect of humans [4]. This happened while the current human being had broken down the priority of tradition due to its limitations as well as managed to get into the pathway of today’s world with a joyous approach [5].
