In Istanbul, some buildings carry more than just the sum of the lives they house; they narrate how the city built itself, and with what taste and anxiety it grew. Rising on Teşvikiye Avenue, diagonally across from the mosque, Güneş Apartment is exactly such a building—perhaps not the most photographed in Nişantaşı, but certainly one of the most frequently passed by. Bearing the signature of Vedat Tek, considered Turkey's first formally educated Turkish architect, belonging to the neighborhood's first generation of apartment development, and uniting the traces of two different eras separated by sixty years on the same facade, makes it extraordinary in terms of architectural history. Güneş Apartment is located in the Şişli district of Istanbul, in the Teşvikiye Neighborhood, on Teşvikiye Avenue, diagonally across from the Teşvikiye Mosque, and directly opposite the Hüsrev Gerede monument.

The History of Güneş Apartment: From Target Stones to a New Neighborhood

The land upon which Güneş Apartment rises belongs to one of Istanbul's latest areas to be opened for settlement. At the end of the eighteenth century, this was neither a district nor a neighborhood; it was a largely wooded ridge used by sultans for archery practice and hunting.

According to rumor, Selim III erected the first target stone (nişan taşı) in the area in 1790-1791, and built a small masjid around this stone in 1794-1795. Sources agree that this early dating is based largely on oral transmission rather than definitive documents; therefore, it should be read with caution. What is certain is that two target stones, one dating to the reign of Selim III and the other to Mahmud II, still stand in the courtyard of the Teşvikiye Mosque today. The term "Nişantaşı," which gives the district its name, derives directly from these stones.

The main intervention that changed the region's fate occurred during the reign of Sultan Abdülmecid. In 1853-1854, the current Teşvikiye Mosque was built to replace the ruined masjid, and during the same period, the establishment of a new neighborhood here was personally encouraged. The phrase "Eser-i Avâtıf-ı Mecidiye Mahalle-i Cedîde-i Teşvikiye" (A Monument of Mecid's Benevolence, the New Neighborhood of Teşvikiye) inscribed on two monument stones in the district is the embodiment of this will set in stone. The name "Teşvikiye" (Encouragement) originates exactly from here: people were encouraged to settle on these empty ridges.

Thus, the plot of Güneş Apartment belongs not to one of Istanbul's spontaneously growing neighborhoods, but to a state-planned settlement project. It is no coincidence that the building is located on the most prestigious axis of the avenue right from its foundation.

The Vedat Tek Signature and an Unsolved Question of Date

Sources agree on the architect of Güneş Apartment: Mehmet Vedat Tek. Born in Istanbul in 1873, the son of Vizier Giritli Sırrı Pasha and poet/composer Leyla Saz, Vedat Bey returned to Istanbul after his education in Paris; he served as Chief Court Architect during the reign of Sultan Mehmed Reşad, and as chief architect of the Ministry of War during World War I. The Grand Post Office in Sirkeci, the Haydarpaşa and Moda ferry terminals, and the building used as the second Parliament in Ankara are his works. Along with Mimar Kemaleddin, he is considered one of the two foundational figures of the First National Architectural Movement. During his years of independent architectural practice, he focused heavily on Nişantaşı, designing numerous apartments in the district, including his own residence. Güneş Apartment is part of this output.

However, the building's construction date remains unresolved today. Common sources like the Cultural Inventory date the structure to 1913-1914. Yet, a photographic record in the SALT Research archives bears the date 1926, and the note on the photograph directly identifies the structure as "Güneş Apartment, built by Vedat Bey on Teşvikiye Avenue in Maçka." M. Burak Çetintaş's work, From Dolmabahçe to Nişantaşı, also dates the row apartments facing Atiye Street to the late 1920s and places Güneş Apartment in 1926.

The ten-year difference between the two dates is not insignificant; researchers examining the district's apartment development timeline, Vedat Tek's stylistic evolution, and the building's facade language—which approaches Art Deco—find 1926 more consistent. As for who commissioned the building, this has yet to be documented. Based on the emphasis "commissioned by Architect Vedat" in Çetintaş's statement, it is occasionally suggested that the building might have been the architect's own investment; however, this remains at the level of rumor and is not based on a definitive record.

The Name "Güneş" and a Namesake Not to be Confused With

Most of Istanbul's historical apartments have borne more than one name; Güneş Apartment, however, has always been referred to by the same name in known records. There is no documented story regarding the origin of the name. Considering the apartment naming traditions of the era, it is known that bright and optimistic names like "Güneş" (Sun) were frequently preferred in the 1920s; however, a specific narrative for this building has not been verified in any source to date.

A warning is necessary here. There is a second building bearing the same name in Istanbul: Güneş Apartment located near Taksim Square, close to the Talimhane entrance. Also known as Namar Apartment, this building dates to the late 1930s, is currently derelict, and has no relation to the building in Nişantaşı. The two buildings are frequently confused on the internet. The one signed by Vedat Tek, located on Teşvikiye Avenue, is the one still used as a residence today.

In the building itself, there is a small surprise for those who know how to read it: on the upper right part of the subsequently added section, the phrase "Yâ Hâfız" (يا حافظ - O Protector) is inscribed in Ottoman Turkish. This expression, calling upon the one who protects, watches over, and spares, is etched onto the facade like a kind of evil eye talisman and remains one of the building's most elegant details.

Architectural Features: Two Eras on One Facade

From Three Floors to Six: The 1968 Intervention

Güneş Apartment's current silhouette is not the direct result of its original design. When first built, the structure was three stories high and looked more like a detached house than an apartment block. In 1968, taking advantage of the municipality's grant for additional floors to the apartments lining Teşvikiye Avenue, three more floors were added to the building. The same application was made to the neighboring Hacı Bekirzâde and Dilek apartments in the same row; thus, this is the transformation story not of a single building, but of an entire avenue.

It is unknown who designed the addition. The possibility that Vedat Tek's son, Nihat Tek, might have had a hand in it has been voiced among researchers, but this thesis has also not been supported by documents. Nevertheless, it is a common consensus that the added floors remain harmonious with the original body in terms of proportion and language, and are considered among the most successful of such interventions in Istanbul.

The Facade: From National Architecture to the Threshold of Art Deco

 Although the building came from the hands of an architect trained in the First National Architecture tradition, it avoids heavy references such as domes and wide eaves. The facade establishes a simple yet measured order that emphasizes vertical rhythm; the control of proportions and the restrained use of ornamentation bring the building closer to the Art Deco trend of the 1920s. It can be said that Vedat Tek scaled down his monumental language in public buildings to a residential scale here, carrying over the attitude rather than the exact style.

Urban Context: Part of a Row

Güneş Apartment cannot be evaluated in isolation. It is a link in the row of apartments extending toward Atiye Street, and right next to it stands the Hacı Bekirzâde Muhiddin Bey Apartment, known today as Lotüs. This row is one of the rare urban fragments that make the transition from mansion to apartment in Teşvikiye legible facade by facade. The building's number of flats, floor plans, and square meter distribution are not available in public sources.

First Residents and the Neighborhood's Social Portrait

There is no record at the name level regarding the first residents of Güneş Apartment available in accessible sources today. However, what can be said about the Teşvikiye of the years the building was constructed offers a solid framework regarding who walked in and out of that door.

The Teşvikiye of the 1920s was one of the most visible stages of the transition from the Ottoman Empire to the Republic. Civil servants and bureaucrat families leaving mansion life behind, physicians, jurists, bank and company managers, and the cadres of the newly established state moved into apartment flats on this avenue. For Istanbul's wealthy classes, the apartment was not a necessity but a choice; it was even a declaration of being modern. It is reasonable to assume that a building located opposite the Teşvikiye Mosque, on the most bustling axis of the avenue, was of interest to this demographic. Any claim going beyond this would be speculation today.

Cultural Memory and Where the Building Stands Today

There is no verified record of Güneş Apartment hosting films, series, or music videos; nor is there reliable information about famous residents documented to have lived here. This does not mean the building's cultural memory is weak; it merely shows that this memory is built through architecture rather than tabloids.

The structure appears in the SALT Research archive with its 1926 photograph; it is registered in the Cultural Inventory under the theme of Vedat Tek buildings; in recent years, it has become one of the stops for independent archives and architectural walks documenting Istanbul's apartment heritage. Within Nişantaşı's dense cultural image stretching from literature to fashion, Güneş Apartment is one of those buildings that doesn't raise its voice but gives the avenue its character. It is a building seen by millions passing through Teşvikiye Avenue, whose name is known by very few; making it one of the few Nişantaşı buildings waiting to be discovered.

Living in Güneş Apartment

Housing in Teşvikiye constitutes one of Istanbul's most supply-constrained and price-protected segments. According to 2026 real estate platform data, the average square meter price for flats for sale in the Teşvikiye Neighborhood hovers around the 160,000 TL band, and the average sales value is at the 24-25 million TL level; on the rental side, there is a band around an average of 90,000 TL. These figures are the average for the entire neighborhood, and flats in registered historical buildings can trade significantly above this average due to the premium of authenticity and location.

Three factors stand out in determining valuation in buildings like Güneş Apartment:

1. Floor Difference: Flats on the original three floors and those in the 1968 addition bear different characters in terms of ceiling height, joinery detail, and view.

2. Restoration Status: Serious price differences can arise between flats that preserve their original details and renovated ones.

3. Conservation Legislation: In structures with historical texture, renovation processes are subject to the approval of relevant conservation boards, and this is an item the buyer must account for from the start.

Conversely, the advantage offered by the location is rare. Teşvikiye Mosque, Maçka Park, the luxury retail axis of Abdi İpekçi Avenue, Istanbul's leading private schools and health institutions, contemporary art galleries, and the avenue's boutique gastronomy ecosystem are within walking distance. Access to the metro and main transportation axes is strong. This profile appeals not to those seeking short-term returns, but to the long-term investor who wishes to hold an asset with limited production, documented cultural value, and a supply that will under no circumstances increase.

Güneş Apartment is a silent summary of Istanbul's relationship with its own past. The story, which began on an empty ridge where a sultan shot arrows, continued with the will to establish a neighborhood, turned into stone through the pen of Turkey's first Turkish architect, and was then rewritten by the 1968 decision to add floors. The "Yâ Hâfız" inscription on its facade still stands there as if wanting to take all these layers under protection. Today, this building, seen by everyone passing through Teşvikiye Avenue, continues to remind us that stone can carry not only space but also memory.

Today, this axis, prominent in "Nişantaşı flat for sale," "Teşvikiye flat for sale," and "Nişantaşı flat for rent" searches, diverges from the standardized residence concept to offer a measured, sheltered lifestyle with cultural depth in the center of the city. While the historical apartments of Teşvikiye Avenue provide the opportunity to establish direct contact with Istanbul's layered past in daily life, it is situated in a location where everything from galleries to boutique restaurants, private schools to health institutions is within walking distance. These structures are the most tangible equivalent of timeless city living.
