Explaining the components affecting the flexibility of open residential spaces in Arak case study

The need for flexibility can be demonstrated from two dimensions, one in theory and the other in the many experiences that have existed throughout the history of architecture. Flexibility requires organization and without it it can lead to confusion and chaos. However, complete flexibility is not possible, because there are boundaries that must preserve the entire system and the main structure. One of the preconditions for flexibility is the separate function of the retaining and separating elements of the building, therefore, the history of flexibility is closely related to the developments and flourishing of skeletal buildings in the new era. Theoretically, there are continuous changes that occur daily, monthly and even annually in environmental and human factors that these changes are generally in the form of three categories: changes in population structure (individuals), changes in rules and standards and Changes in values, architecture in order to adapt to these changes and maintain the quality of space, change is necessary, a change that according to the definitions, is considered flexible. In residential spaces, the ability to adapt the space to the personal needs and tastes of users is essential to maintain the desirability of the space. Factors such as increasing the number of children, change of residents and independence of children from the family, create the need for separation or integration in the housing unit or units. Also, the growth of people's age and change of their tastes is one of the factors that cause physical changes in the residential space.
