This structure which is used as Head Office by Axa Insurance neighbors to İstanbul Fındıklı, Galata Port Project. The structure has been subjected to partial revisions in line with the needs emerged during the design period, however, because of the day light problem due to attached buildings and low floor heights has necessitated a more substantial solution. In consideration with this fact, the vertical circulation of the building has been shifted to the center of the structure and an atrium space has been formed. This aims the homogeneous distribution of day light within the building. Besides, in order to eliminate the lower elevation of the entrance area of the building, the floorings were repaired and a second atrium has been planned inside the facade. In this way the used depth of the building has been decreased and the illumination means have been improved. Within the inner space, the elevator wall which faces to the atrium has been planned as vertical green garden.
