Kartal Office Project is located in Kartal District of Istanbul city. In the design process of the office, the priority was to be sustainable for improving working standards and at the same to be technological for adapting to the new world order. The two pieces are interwoven and created a corridor of human and nature circulation that connects the pieces together. In the form of mass, two slits were created to look at the road and the sea. In order to raise employee happiness and workplace standards, common areas are often featured on the floors of the project. In order to meet quick coffee breaks and to get together, it is desirable to design a building where the connection with the outside world is not interrupted.
