The Çankaya Campus is home to several buildings, including the mansion and stretches over 195 hectares (480 acres) of land with its unique place in the history of the Turkish Republic.

In 2014, the president moved to the newly built Cumhurbaşkanlığı Külliyesi, with Çankaya Mansion becoming the official residence of the Prime Minister.

[4] When Mustafa Kemal Atatürk, who would go to serve as the first president of Turkey, saw the building in 1921, he took a strong liking to the property and purchased it from Bulgurluzâde Tevfik Efendi for 4500 liras.

[citation needed] In 1924, architect Mehmet Vedat Bey undertook some renovations on the Kasabian Mansion, including adding a second floor for new bedrooms, a framed window entrance at the front, a pantry and kitchen at the rear, and a tower onto the side.

Having witnessed to a number of defining moments at a time when the War of Independence was fought and the Republic was founded, today, it is carefully preserved as a tribute to Atatürk's memory.

Despite the fact that expansion and renovation activities were made twice at the Museum Mansion, when it remained inadequate to meet the gradually increasing needs, it was decided in 1930 to have a new building constructed.

Holzmeister, who started the construction of the Çankaya Mansion at the beginning of 1931, completed it in a short period of time, such as 1.5 years, and delivered it in June 1932.

The Çankaya Mansion, which reflects the combination of the traditional Turkish house style with the ease of life of the West, besides being the residence and working areas of Atatürk from 1932 until his death, since it was designed by taking his requests and warnings into account, it is also of value and importance from the aspect of showing his taste and the lifestyle he envisaged.

After Atatürk, the Çankaya Mansion gave services, both as a residence and as an office building to İsmet İnönü, Celal Bayar, Cemal Gürsel, Cevdet Sunay, Fahri Korutürk, Kenan Evren, Turgut Özal and Süleyman Demirel, who assumed the duty of President.

The Glass Mansion, which changed considerably with the repairs made in various periods, was restored in 1994 and a 300 meters square bedroom unit was added and it started to be used again at the beginning of 1996 as a place where foreign heads of state could stay as guests.

The project, which was prepared by architects Mustafa Aytöre and Orhan Genç, is used as a workplace of the units of the Presidency and the New Service Building has meeting and reception rooms and the official office and study of the President.The social facilities are composed of a shooting polygon, a sports hall and cafeteria and has a construction area of approximately 2,000 meters square.

The Press Conference Hall, which was designed by being connected to the New Service Building, was built underground in order not to spoil the structure of the tree grove within the Campus.

The greenhouse and the Parks and Gardens Directorate building, which is composed of two stories on a total area of 1,590 meters square, was completed in 1999 and started services.

Even during coups the Çankaya Mansion played its part with generals Evren and Gürsel becoming president and Celal Bayar holding a pistol at coupists in an attempt to save himself.
