In terms of presenting the visual, functional, and psychological effects of indoor plant design studies to the wider masses in society, the spaces on university campuses with diverse user profiles have special importance. In this study, a plant design project was carried out in the library building with multi-space usage in Osmaniye Korkut Ata University Karacaoğlan Campus. The study was carried out in 3 stages. In the first stage of the study, the areas where the plant design study will be carried out were determined. In the second stage of the study, the current situation of the space was analyzed and the problems that needed to be solved with plant design were determined. In the third stage of the study, AutoCAD, 3ds Max, and Lumion 10 computer software were used to visualize the proposed plant design studies.
