Flexibility is a design approach that enables you to meet these changes in the face of changes and developments depending on space, user and function in the process. Today, technological developments, rapid changes in education systems, etc. have made it necessary for the education systems and their learning environments to be changeable and adaptable to the changes that may be experienced. This situation made the concept of flexibility even more important in the organization of educational buildings Prof. Dr. Herman Hertzberger, who has made important studies on educational matters, has been proposing to withdraw from the relation between space and the user by bringing the user to the fore in the school and housing projects he has produced since the 1960's. Hertzberger adopted a design approach that centered on open-ended solutions and user-centered projects in his school projects, allowing architects and users to interact and communicate with each other and produced flexible solutions on this count. In this study, the design approach of Herman Hertzberger 's school buildings was examined in the context of the flexibility strategies revealed as a result of the literature review, and the analysis of the schools which are formed in accordance with the flexible design concept and the inferences that will shed light on the new designs have been made.
