Architecture of Turkey or Turkish Architecture in the Republican Period refers to the architecture practised in the territory of present-day Turkey since the foundation of the republic in 1923. In the first years of the republic, Turkish architecture was influenced by Seljuk and Ottoman architecture, in particular during the First National Architectural Movement (also called the Turkish Neoclassical architecture movement.) However, starting from the 1930s, architectural styles began to differ from traditional architecture, also as a result of an increasing number of foreign architects being invited to work in the country, mostly from Germany and Austria. The Second World War was a period of isolation, during which the Second National Architectural Movement emerged. Similar to Fascist architecture, the movement aimed to create a modern but nationalistic architecture.
Starting from the 1950s, isolation from the rest of the world began to diminish, which enabled the Turkish architects to experiment with new styles and become increasingly inspired by their counterparts in the rest of the world. However, they were largely constrained by the lack of technological infrastructure or insufficient financial resources until the 1980s. Thereafter, the liberalization of the economy and the shift towards export-led growth paved the way for the private sector to become the leading influence on architecture in Turkey.
For pre-1923 Turkish architecture, see Ottoman architecture.
Main article: First national architectural movement
The First National Architectural Movement (Turkish: Birinci Ulusal Mimarlık Akımı) was an architectural movement led by Turkish architects Vedat Tek (1873–1942) and Mimar Kemaleddin Bey (1870–1927). Followers of the movement wanted to create a new and "national" architecture, which was based on motifs from Seljuk and Ottoman architecture. The movement was also labelled Turkish Neoclassical architecture, or the National Architectural Renaissance. Other prominent followers of this movement were Arif Hikmet Koyunoğlu (1888–1982) and Giulio Mongeri (1873–1953). Notable buildings from this era are the Istanbul Main Post Office (1905–1909), Tayyare Apartments (1919–1922), Istanbul 4th Vakıf Han (1911–1926), State Art and Sculpture Museum (1927–1930), Ethnography Museum of Ankara (1925–1928), Bebek Mosque, and Kamer Hatun Mosque.
The Bauhaus style Florya Atatürk Marine Mansion (1935) and the Art Deco style Ankara Central Station (1937) are among the notable examples of this era. As there were not enough architects in Turkey until the 1950s, various architects were invited by the government from Germany, Austria, Switzerland and France, in order to manage the rapid construction of the new capital Ankara. About 40 architects and urban planners designed and oversaw various projects (mostly in Ankara, and to a lesser extent in Istanbul and Izmir) between 1924 and 1942. Among them were Gudrun Baudisch, Rudolf Belling, Paul Bonatz, Ernst Arnold Egli, Martin Elsaesser, Anton Hanak, Franz Hillinger, Clemens Holzmeister, Henri Prost, Paolo Vietti-Violi, Werner Issel, Hermann Jansen, Theodor Jost, Heinrich Krippel, Carl Christoph Lörcher, Robert Oerley, Bernhard Pfau, Bruno Taut and Josef Thorak.
Selected examples of buildings from this era are the Bauhaus style Florya Atatürk Marine Mansion (1935) designed by Seyfi Arkan; the Art Deco style Ankara railway station (1937) designed by Şekip Akalın; the Court of Cassation building (1933–35) designed by Clemens Holzmeister; the Faculty of Languages, History and Geography building (1937) of Ankara University designed by Bruno Taut; and the Grand National Assembly of Turkey building (1938–63) designed by Clemens Holzmeister.

The Stripped Classicism movement of the late 1930s and early 1940s in Europe and North America sought a modern interpretation of Neoclassical architecture. The movement had a particularly notable impact on Fascist architecture in Italy and Nazi architecture in Germany, which aimed to develop the modern versions of the architecture of the Roman (Italy) and Holy Roman (Germany) empires, according to their ideologies. In the same period, there was a trend towards creating a new national architecture in Turkey, which was called the Second National Architectural Movement (Turkish: İkinci Ulusal Mimarlık Akımı). The foreign architects employed in Turkey in this period (especially from Germany and Austria) played an important role in the introduction of this architectural movement and its stylistical characteristics. The pioneers of the movement in Turkey were Sedad Hakkı Eldem, Ekrem Hakkı Ayverdi and Emin Halid Onat. In order to lead this movement, Sedad Hakkı Eldem, who was a professor, held National Architecture seminars at the Mimar Sinan University of Fine Arts, focusing on the traditional Turkish house styles.
Similar to their contemporary equivalents in Europe and North America, the government buildings of this style in Ankara and Istanbul had typically large proportions (high ceilings, high windows, etc.) in order to give the impression of a strong state authority. Some of them also had monumental facade designs reminiscent of Neoclassical architecture; but with more modern and plain rectangular shapes, symmetry, simplicity, and a general lack of ornateness.
Some of the buildings related to this style are the Ankara Opera House designed by Şevki Balmumcu (1933–34) and renovated by Paul Bonatz (1946–47); the TCDD General Headquarters Building designed by Bedri Uçar in 1938; Istanbul University Faculty of Science and Faculty of Literature buildings (1944–52); Anıtkabir (1944–53); Istanbul Radio Headquarters (1945–49); Şişli Mosque (1945–49); and the Çanakkale Martyrs' Memorial (1954–60). The movement was particularly influential between 1935 and 1950. From the 1950s, the influence of this style started to diminish due to the next wave of influences, especially International Style and Rationalism.
At the beginning of the 1950s, a new generation of architects such as Nevzat Erol, Turgut Cansever, Abdurrahman Hancı, Cengiz Bektaş, Hayati Tabanlıoğlu, Enver Tokay, İlhan Tayman and Yılmaz Sanlı became more influential in the architectural arena. These were architects who either studied in Europe or had information of the modernist architecture of the time. Their quest for modernist architecture was in line with the International Style and Rationalism. However, the development of the Turkish economy was an important factor as well. Even though Turkish architects were able to follow up on the modern design of important architects of the time, they were constrained by the lack of technological infrastructure or insufficient financial resources.
Selected examples of buildings from this era are the Anadolu Club Hotel (1951–1957) in Büyükada designed by Turgut Cansever and Abdurrahman Hancı; Hilton Istanbul Bosphorus (1952–1955) designed by Skidmore, Owings & Merrill and Sedad Hakkı Eldem; Istanbul Municipality Headquarters (1953–1960) designed by Nevzat Erol; Emek Business Center (1959–1965) in Ankara designed by Enver Tokay and İlhan Tayman; and Tekel Headquarters (1958–1960) in Istanbul designed by Yılmaz Sanlı and İlhan Tayman.
One of the most important developments of this period was the establishment of the Chamber of Architects of Turkey in 1954. Various professional organizations for architects had existed beforehand, but there were no laws for the architectural profession until 1954. Brutalist architecture become popular during 1950s, the work of Behruz Çinici in Middle East Technical University is the best example of this era.
Following the 1960 coup d'état, Turkey endured various kinds of political and economic crises which affected the construction industry as well as the architectural sector. Despite these hardships, architects were able to design some important buildings. Abandoning Rationalism, Turkish architects tried to design their buildings in more flexible and fragmented forms. Important works from this period are the Vakıflar Hotel in Istanbul (1968, today the Ceylan Intercontinental Hotel), Middle East Technical University Campuses (1961) in Ankara, Istanbul Manufacturers' Market (1959), Turkish Historical Society Building (1967), Grand Ankara Hotel (1960, today the Rixos Grand Ankara Hotel) and Atatürk Cultural Center (1969) in Istanbul.
As a result of economic and social turbulence, architecture in Turkey suffered also in the 1970s. There were no significant breakthroughs during this period. Some important designs from the 1970s are the Turkish Language Association Building (1972), Atatürk Library (1973) and Abdi İpekçi Arena (1979).
In January 1980, the government of Prime Minister Süleyman Demirel began implementing a far-reaching reform program designed by then Undersecretary of the Prime Ministry Turgut Özal to shift Turkey's economy toward export-led growth. These reforms had a positive effect on the construction industry and architecture. New methods such as prefabrication and curtain wall systems were introduced to Turkish architects and contractors in the 1980s. In addition, steel, aluminum, plastic and glass production increased, which allowed architects to free themselves from rigid forms.
Until the 1980s, the government sector was the leading client when it came to architecture and construction. However, the liberalization of the economy paved the way for the private sector to become the leading influence. Notable architects from this period include Behruz Çinici, Merih Karaaslan, Sevinç Hadi, Şandor Hadi, Ersen Gürsel, Mehmet Çubuk, Doğan Tekeli, Sami Sisa, Emre Arolat, Murat Tabanlıoğlu, Melkan Tabanlıoğlu, Hüsrev Tayla, Doğan Hasol, Atilla Yücel, Sema Soygeniş, Murat Soygeniş and Kaya Arıkoğlu, among others.
Buildings are the largest energy consumers, and there are substantial opportunities for energy savings in both new build and renovations. The Organisation for Economic Co-operation and Development (OECD) has said that more could be done to improve the energy efficiency of buildings, and that tax incentives offered for this would create jobs.: 62 Turkey was a co-leader of the group discussing zero-carbon buildings at the 2019 UN Climate Action Summit, and the city of Eskişehir has pledged to convert all existing buildings to zero emissions by 2050. Such energy efficiency improvements can be made in the same programme as increasing resilience to earthquakes in Turkey. However, in 2020 gas was subsidized.: 18 Increasing the proportion of passive houses has been suggested.
In rural areas without a piped gas supply, heat pumps could be an alternative to wood, coal and bottled gas: but buying a heat pump is rare as it is very expensive for householders as there is no subsidy.: 29 However, owners of larger properties such as shopping centres, schools and government buildings have shown more interest.
Direct geothermal heating (not to be confused with heat pumps) installed capacity totaled 3.5 GW thermal (GWt) in 2020, with the potential for 60 GWt, but it is unclear how much is low-carbon. According to a 2020 report commissioned by the environment ministry and the EBRD further research on Turkish geothermal is needed: specifically how to limit carbon dioxide venting to the atmosphere.: 283, 284
There is no data on the carbon intensity of cement.: 13 Emissions from cement production could be lessened by reducing its clinker content—for example, by making Limestone Calcined Clay Cement, which is only half clinker. The second-largest reduction could be made by switching half the fuel from hard coal and petroleum coke (petcoke) to a mixture of rubber from waste tires, refuse-derived fuel and biomass. Although the country has enough of these materials, most cement kilns use coal, petcoke or lignite as their primary energy source.: 166 More cross-laminated timber could be used for building, instead of concrete.Further decarbonisation of cement production would depend heavily on carbon capture and storage (CCS).: 109 Despite Turkey's earthquake risk, CCS may be technically feasible in a salt dome near Lake Tuz or in Diyarbakır Province.
