In the study, research is conducted to read the phenomenon of place attachment, which is defined in the literature on permanence, through transformation and flexibility. Through theoretical research, it can be read that flexibility works in parallel with time, mobility, transformation and the adaptation of space to transformations. The view of flexibility in the article is also in this orbit. The researched case is how the concept of flexibility, which is the adaptation of the space to the individual, is integrated with the concept of place attachment, which is the adaptation of the individual to the space. Therefore, the purpose of the study is; is to make a reading of place attachment in the axis of transformation by revealing the cross sections of flexibility and belonging concepts through residential applications.The concept of place attachment arising from the interaction of the subject and the object is regarded as relationality. It is the most basic trigger intervention in the establishment of the subject-object relationship. The intervention brings the personalization of the space and the production of meaning. At the same time, the continuity of the intervention brings with it spatial transformation, and it is immanent with flexibility.This situation is discussed through 1 + 1 and 1 + 0 housing practices in Cihangir district of Istanbul. The fact that the selected houses have different forms of flexibility expands the scope of the debate and strengthens the ground. Thus, the cases mentioned in the theoretical background; read through interview and observation methods. Spatial traces, actions and discourses in different flexibility typologies have been revealed. It is disclosed that the transformative and flexible trigger the place attachment phenomenon rather than the static one. The phenomenon of place attachment is fed by the transformational, the transformative, and even the transformation itself.
