Designing and building easily navigable and memorable environments is one of the main roles of interior designers. Wayfinding is defined as the ability to navigate through space without feeling lost. Interior designers are responsible for incorporating principles of wayfinding in the built environment to improve occupants' experience.  The main purpose of this paper is; 1) to write an overview of wayfinding implications related to interior design and architecture that improves building users' navigation in the built environment, 2) to employ the wayfinding elements to an institutional building. The aim of this project is to help new students and visitors reach their destinations easily without being lost. A qualitative research analysis, thematic approach, is used to review credible scholarly journal articles and books with the relation of occupants' behavior and wayfinding elements. Also, a case study is conducted in an institution-building to find out wayfinding issues and redesign the building through employing an evidence-based design approach. This paper explored a variety of techniques that interior designers and architects should use when designing new buildings.
