The method of linking the institutional identity, the visual identity and the interior design of administrative buildings has been studied through several models, which are a step that leads us to solve the design problems resulting from the loss of a unified philosophy in interior design between the different spheres within The administrative institution as well as the lack of interest of some institutions in designing an integrated corporate identity, which led to problems For multiple users of a void, one designer's role should not start from the end of the other. The study followed the descriptive and analytical approach and emphasized the importance of accessing the designer's intellectual capabilities and experiences to a design that achieves visual integration within the internal space with a unified identity, and the study ended with the most important findings and recommendations.
