In 1948, our company is established in Ankara as Garanti İnşaat Ltd. First contracted work is the Carpentry Works of the National Assembly Building, on 8th November 1948. Headquarters moved to İstanbul in 1952. Garanti İnşaat concentrated on government investment projects, public works and industrial facilities.

In 1976, Koç Holding acquired a 62% stake in Garanti Bankası. As Koç Holding acquired an 80% interest in Garanti İnşaat, it became a part of the Koç Group in 1982.

The name of the company was then changed to Garanti Koza.
