Considering the vast changes in different aspects of life and various ways of earning livelihood, flexibility in contemporary housing design can be regarded as an appropriate solution in order to prevent from discreteness in interactions within the society and environment and among people. That is because a residence must be designed according to the changing needs of modern human. Traditional houses in Iran have already contained this concept, in modern era however, such viewpoint towards housing cannot be seen so often. Flexibility refers to the idea of adaptation throughout the time. Therefore it can be said that a flexible settlement is a house that can be adapted with the needs of the users and will lead to understanding the users’ expected demands with their own cooperation. Peoples’ cooperation in this process will increase the possibility of adaptation of housing with their needs which will eventually increase the general satisfaction of the housing. This research discusses the issue of flexibility and the related concepts in the field of housing with emphasis on some residential projects. Every settlement is depended on its user and the ground for its adaptation. Therefore, in terms of general design, we can say that settlement is dependent on both the environment and the user. Since human beings normally demand variety and  monotonous environmental conditions make human beings unsatisfied and bored; they usually have a favorable and positive view towards changes in their living environment. These varieties can range from some minor changes up to basic ones such as a change in the residential house itself. Flexibility in architectural design indicates variety. Such variety includes the possibility of adjustment and compatibility of a residential unit throughout time. It will eventually lead the building to show new varieties of its own. In order to demonstrate flexibility, the architects have to put the probable needs of the users into consideration in the process of designing. In other words, a “long-term thought” is required in designing.Flexibility in housing can be investigated from two points of views: first, from users’ point of view and secondly the innovative construction. Designing consists of four main issues: (1) structural system; (2) servicing spaces; (3) architectural design; and (4) facilities for environmental flexibility. The present study tries to express the concept of flexibility as a “new form of challenging architecture”. This is done using some examples and instances. From such viewpoint, the goal this study tries to attain is to survey the limitations and boundaries of flexible designing. This is done by analyzing the selected items. This way, the architect can turn flexibility into an opportunity and produce creative options in his/her work and design. The present study was conducted using library-based method and case study with the aim of studying and discussing the conceptual and operational grounds of housing design in different countries. The structure and main framework of the present study stands on the idea that flexibility can be used for  housing development in all eras and periods as a general concept and includes different types itself.

Already in a variety of buildings with different uses, what would seem more architectural design, the changes after utilization by users that this change in terms of non-compliance with design requirements and not due to changes in other aspects, such as engineering and pre-operation. Sometimes encountered with a sudden change in the design process and according to the traditional structure of the design process, this change does not apply in other dimensions and design errors during the operation, to show the changes will be binding, it could be next a model to follow design changes and pre-operation would lead to elimination; as necessary. Building Information Modeling (BIM) by removing complexity in the design, manufacturing, integration of information with possible changes in the other components of the structure, anticipate and reduce errors after the operation and construction. With technology development, process improvement and change the industry has improved, but still compact construction industry based on the traditional process, with the architectural design or building design, constructed by contractors. This is while, the building of new systems and due to the changing demands of the employer, are very complex, so that we add to this complexity, architects, owners and contractors to align themselves with these developments, in the wake of Operation changes into the design drawn on the body, it's important to be consistent and comprehensiveness of information between other elements of building construction creates a problem, since more of the architect's plans need to be integrated and followed this interference with the program at all stages make a pre-operation. In fact, building information modeling, a new change in the design and construction industry is documenting, modeling, building information, information about the whole building gives us the full documentation and integration into a database gives us. All of these parameters are therefore connected to each other, any change in the model of an object, the entire project will affect all aspects, building information modeling, data includes actual building is only two-dimensional maps, which are common Maps drawn with CAD found not formed. Building Information Modeling, a common mistake is called as a digital model generated by CAD software in a process known as Building Information Modeling. Construction industry due to the large number of documents it is much more complicated than ever. BIM new promising tool in architecture, engineering and construction industry, which will build a virtual model before the actual construction of buildings on the main field allows information. In fact, this model designs because this method, using the building information and it is also the most important stage design. Building and weaknesses through analysis software is documented. In enhancing the effectiveness of the do the right thing, in this method, two-dimensional plan was rejected and assessments in specific applications with methods to identify the areas and their dimensions are considered qualities, at different times of exposure, etc. is checked.
In the construction of a project, including design partnership with the consultancy, construction and post-run (after the operation) is, in fact semantic knowledge building must be provided, building information model, common architecture Other aspects of the project such as building provides structural and semantic knowledge, based on continuous improvement approach, which supports the evolutionary changes simply and recovery. It improves with time-saving schematic design, design changes and development, creation and coordination between the various elements of project design and control documents in advance of the operation increases productivity. The main objective of this study was to develop methods to improve the architectural design stage before an exploit is in fact to determine the effectiveness promoter factors, using the building information model, the final design is done. The rise of the more complex, faster and build sustainable development in the form of improved technology makes BIM drawing because the traditional activities are not able to meet these pressures. It is hoped that with the widespread use of building information modeling in the field of construction, the cost of future performance and reduced use and improved performance of the operation to reduce errors. The Building Information Modeling as an innovative way to design, construction of process before and after the operation, implementation and management, compared with more traditional methods of design and attitude as human activities that model, instead of seeing it as an object-oriented approach or a special software. In fact, BIM improves the automation industry and process two-dimensional animation project, has been integrated into the workflow in the batch process, the ability of computing, networking and data information and knowledge society maximized and errors are reduced.

  The appearance of animal images on the archaeological remains is always considered as an evidence to determine their natural living and their role in human's cultural and ritual life. Animal imagery is found in every medium of art in the Proto Elamite period include stone statuette, pottery, metalwork and finally seal impressions. The glyptic art and pottery through their diversity and the nature of their symbols provide the researchers with the basic information with which to piece together the iconography and the social and economy history of the Proto Elamite period. This paper examines serpent, turtle and feline imageries and related pastiches on two media at Tepe Sofalin, including seal impressions and pottery fragments.

Archaeologists define the Proto-Elamite phenomenon by the appearance of Proto-Elamite writing, the first form of local writing in Iran on tablets in many cases together with specific types of other management tools and pottery, over a vast geographical territory across the Iranian plateau. Different explanations have been offered to account for this spread and the shift from a Mesopotamian-oriented culture during the earlier period (Late Uruk) to a predominantly Iranian-oriented culture during the late fourth and early third millennium BCE. However, up to now, most of these explanations have been concentrated on the recovered material culture from Fars in the southern part of the plateau and Khuzestan in the southwest. New discoveries from sites on the northern fringes of the plateau depict a fresh and more complete picture of this enigmatic phenomenon. The new excavations and surveys conducted in the settlements that contain the material culture of this horizon have significantly added to our knowledge about the formation and spreading processes of this horizon. Cultural material recently recovered from these sites have extended the Proto-Elamite territory even further, have changed our understanding of the relationships among them and the potential ways this cultural horizon was shaped and diffused. In this paper, we present some of the newly discovered evidence from these sites including but not limited to: Sofalin, Shoghali, Ozbaki, Gholi Darvish and compare them with our older understanding of the presence of this cultural horizon in the center and northern parts of the Iranian plateau.
