Kagithane is simply adjacent to the Buyukdere axis, the main road of Istanbul on the ridge just separating the two parallel valleys, along which the major capital flows and investments of the metropolis in the 19th and 20th century occurred. The Buyukdere axis converted since late 80s into the Central Business Corridor of Istanbul, with a remarkable vertical skyline development, housing all major private banks of Turkiye.

From late 80s onwards, the first wave of transformation took place in Kagithane. As the metropolis grew on, the area no longer remained periphery, but was quiet centrally located. Relux KGT257 is a residential project locates on the center of transformation of Kagithane. A number of issues were at play in the organization of the site, especially the orientation and height  in a high-rise neighborhood. Long and narrow site are surrounded by high rise buildings. On the south face of the site there are two wide neighbor buildings which define the orientation of Relux KGT257 . The flats are oriented through the south-east and west facades. The circulation core and corridors are replaced to the north façade which is limited with an wide tall building. Besides the residences, Relux KGT257 has a wide program contains a social center, a roof terrace with a lounge bar, and offices which can be organize for mixed purposes.
