SPK head office is part of the new financial center that has come into prominence in Atasehir in Istanbul. It is composed of two elliptic towers that do not affect each other’s views. The character of the building is determined decisively by the geometric combination of the materials. The towers, which are 40 and 35 floors high, have a square structure in between them, serving as an entrance to a significant number of offices and businesses. These buildings are home to many private offices, two head offices, a bank and many social activity areas.
