Çankaya Mansion

The Çankaya estate occupies a large, wooded and secured grounds containing several distinct buildings grouped around gardens and service areas. Estimates of its extent range from about 195 hectares (480 acres) to roughly 1.77 square kilometres (438 acres), and the layout reflects successive phases of construction from the original vineyard house through mid‑20th century additions and late‑20th century service complexes.

The Museum Mansion, the estate’s oldest standing house, retains the bones of the original family dwelling while showing clear early Republican alterations. In 1924 the building gained a second floor for sleeping rooms, a framed windowed entrance at the front, a pantry and kitchen at the rear, and a small side tower; central heating was added in 1926. The interior preserves original fittings and furniture, the house opened as a museum in 1950, and a comprehensive restoration was completed in 1986, followed by ongoing conservation to protect its historic furnishings.

The main Çankaya Mansion completed in 1932 sits as a two‑storey residence over a basement. The ground level serves for offices and formal reception while the upper floor contains private living quarters. Structural components and part of the interior work were brought from Austria during construction. The façades on three sides are faced with Ankara stone, and terraces and a formal garden area including a rose garden and flagpole define the immediate exterior. The mansion remains the focal architectural element of the campus.

The Glass Mansion is a single‑storey, high‑quality residence finished in 1936 and later adapted for official hospitality. It underwent restoration in the 1990s and was enlarged with an approximate 300 square metre bedroom unit before reopening for state guests in early 1996.

A small stone masonry building that served the aide‑de‑camp functions sits on the grounds; it is a single‑storey structure whose chronology is uncertain in published records, with a stone‑paved rear courtyard showing the date 1928. The building has seen several restorations and later additions as the campus needs evolved.

About fifty metres behind the main mansion lies the underground shelter constructed in the 1940s as a protected presidential working space intended for use in the event of a nuclear attack. The shelter includes a reinforced steel door and internal fittings provided to support continued operations under emergency conditions.

Gate No. 1 marks the formal approach and was rebuilt in 1999 with a bronze gate and andesite stone cladding to harmonize with the estate’s architecture; the rebuilt entrance incorporates landscaping, a main gate building of roughly 230 square metres and an adjoining military unit building of about 140 square metres.

The Administrative Building, completed in 1985, rises two storeys above a basement on a footprint of approximately 3,546 square metres and houses the Preservation Directorate together with administrative and financial units. The New Service Building, begun in 1983 and opened on 29 October 1993, contains meeting and reception rooms and the official office and study used by the President in its period of operation.

Social and support facilities added in the 1990s include a three‑storey complex of about 2,000 square metres containing a shooting range, sports hall and cafeteria, with on‑site health centre upgrades carried out in 1996 and 1999. The reception and press facilities built at the turn of the century include a reception hall and foyer totalling roughly 2,650 square metres opened on 29 October 1998, and a press conference hall of about 1,250 square metres opened on 29 October 1999; the press hall was constructed underground in order to preserve the grove of trees above. A new General Secretariat and State Supervisory Board complex replaced an older service block with six interconnected building blocks, and a two‑storey greenhouse and Parks and Gardens Directorate building of about 1,590 square metres was completed around 1999.

Across the estate most historic houses and later additions have undergone restoration or enlargement at different moments in the 20th century, and many buildings remain in use after conservation or adaptation for official and service functions.
