Kizilkaya Business Center Projects were created from the idea of building and selling business centers on three separate lands located on Çankaya, İzmir. After the construction of Kızilkaya 1 project, the rough construction and plastering were completed and the building was sold as a whole. The construction of the business center which was sold to another group was completed in line with the willingness of the investor group. The related building today serves as Levent Toptan. The construction and sale of Kızilkaya Business Center 2 project was carried out by Mahir Ekin Vural İnşaat. Today the business center serves as Turkay Plaza. Right after acquiring the license and starting the construction, the project has been sold to Turk Metal Union and still serves as Turk Metal Union building.
