The design concept for this project is inspired by stratigraphy, an archaeological branch that examines the arrangement and succession of layers to determine the timeline of remains. This concept aligns with the historical layers of Haydarpaşa Train Station. A key element is the use of iconic interior arches, which, after numerous iterations, were incorporated as exhibition features. These arches were used repetitively and rotated in different directions to create a three-dimensional effect and a sense of delineated spaces. Openings in the arches allow viewers to see through to other layers, enhancing the layered effect. The layering concept is also applied on a larger scale, with different spaces located on various levels. This design allows visitors to view the exterior of the Haydarpaşa building from different heights and see archaeological remains from various angles.

Materials and colors were chosen to blend cohesively with the building’s existing elements. Fabrics were predominantly used in the library, study, and seminar spaces to support acoustics. In the courtyard, warm and earth-toned colors were selected to blend with and contrast the existing green beams. Greenery and transition areas were intentionally aligned with these beams to create meaningful relationships within the space. Additionally, accessible and universal design principles were prioritized to ensure inclusivity and navigability for all visitors.
