The General Staff Building (Turkish: Genelkurmay Başkanlığı Karargâh Binası), opened in 1929, the design is owned by Clemens Holzmeister, the administrative building of the Turkish Armed Forces in Çankaya, Ankara.

The Chief of Staff, operating in Ankara Ziraat Mektebi, sought to donate one Turkish farmer's field upon the search for a new headquarters building.

However, with the order of the Chief of General Staff Marshal Fevzi Çakmak, the field was purchased at a rate of 5 kuruşs per square meter.

One of the first state constructions in the State District, the pavilions of the building offer a massive and plain appearance with square windows equally spaced on all surfaces.

Half-cylinder spaces that are not present at the ends of the wings extending forward on both sides of the entrance and forming the arms of the "H" are included in the design for the same purpose.
