Re-functioning is one of the most important fields of study for architects, interior architects, and designers to have an awareness of the protection of existing cultural buildings. It is possible for historical buildings of cultural importance that have lost their function to come to life in the city through re-functioning. In this direction, to protect cultural assets and transfer them to future generations, the subject of Biruni University Interior Architecture and Environmental Design, 2021-2022 Spring Semester, Interior Architecture Project IV course was determined as temporary accommodation design and Üsküdar Paşalimanı Flour Factory which is located in Istanbul/Turkey was given as the project area. Within the scope of the study, the students were expected to design the building, which is idle in the city, with a temporary accommodation function, taking into account the cultural and social needs of the region. Out of 21 student projects that were successful in the project studio, 10 projects were selected to form the non-random analog sample of the study. In the study, a biaxial methodology was used and the extent to which the student projects approached the evaluation criteria determined by using the “causal comparison model”, one of the quantitative research methods, was presented in a table. As a result, when the student works are evaluated, it is seen that different design approaches that both consider the integrity of the building and bring contemporary suggestions have been developed and the importance of the concept of conservation has been adopted to a great extent.
