Rising on Eski Büyükdere Avenue with a direct connection to 4. Levent metro station, Istanbul Sapphire was designed as Turkey's first ecological skyscraper and remains the tallest tower in the Levent business district. The building's title deed is registered in Kağıthane's Emniyetevleri neighbourhood, while in the market it is positioned as a Levent address.

Developer and Architect
The developer is Kiler GYO and the main contractor is its group company Biskon Yapı. Biskon Yapı has served as the contractor for projects developed by Kiler GYO since 2004. The architectural design belongs to Tabanlıoğlu Architects. The double-skin façade, garden floors placed every three storeys and communal living floors placed every nine storeys are the defining elements of the design.

Completion Year
Construction began in 2006. The building was completed in 2011 and opened for use the same year.

Tower and Unit Mix
The project consists of a single tower. It has 64 floors in total (54 above ground and 10 below ground), 47 of which are residential. The tower contains 187 residential units. Unit types range from 1+1 to 5+1, with 12 different floor plans including intermediate types (1.5+1, 3.5+1, 4.5+1). The upper floors feature residences with private terraces and duplex units.

Unit Sizes (m²)
Residences start from 120 m². Standard 1+1 units range from 120 to 170 m², 3+1 units from 220 to 260 m², and 3.5+1 and 4+1 units from 340 to 360 m². Large duplex and terrace units on the upper floors range from 440 m² to 750 m². The wide spread of sizes even within the same room count reflects the project's variety of floor plans.

Amenities
Social facilities are distributed across different levels of the tower. The 5th floor houses an indoor swimming pool, jacuzzi, sauna, Pilates and yoga studios, a fitness centre and massage rooms. The 6th floor contains a library, games room, multimedia area, bar, lounge, children's play area, business centre and meeting rooms. The 39th floor is home to a 9-hole golf practice area and simulation rooms. The golf practice area covers 1,650 m² and the 140 m² swimming pool overlooks the Istanbul skyline.

Residences are equipped with a smart home system with touch panels controlling lighting, heating and cooling, as well as service requests. 24/7 concierge service, indoor parking and round-the-clock security are standard. The observation deck at the top of the tower offers a 360-degree panorama of the city and contributes to the building's recognition.

Since 2024, the commercial floors at the base of the tower have been converted to office use. Kanyon, Özdilek Park and MetroCity are within walking or short driving distance for daily shopping needs.

Current Price Range
As of September 2026, prices for residences for sale at Istanbul Sapphire range from TRY 230,000 to TRY 255,000 per m², with an average of around TRY 243,000 per m². This figure is well above the overall average for the Levent residence segment and reflects the project's premium position in the area.

Current ranges by unit type:

• 1+1 residences (130–140 m²): TRY 33–35 million
• 3+1 residences (270–300 m²): TRY 63–75 million
• Larger 3+1 and terrace units (over 350 m²): TRY 85 million and above

High floors, Bosphorus views and terraces are the main factors that push prices towards the top of the range. Furnished residences are also positioned in the upper part of the range. The figures reflect current asking prices in the market. Final transaction prices may vary depending on negotiation.

Transportation
The building is directly connected to 4. Levent station on the M2 metro line. The business districts of Levent, Maslak and Zincirlikuyu are a few minutes away via Eski Büyükdere Avenue and Büyükdere Avenue. Access roads to the Fatih Sultan Mehmet Bridge and the 15 July Martyrs Bridge are close by, shortening the journey to the Asian side. The metro line connects to Marmaray via Taksim, Şişhane and Yenikapı. For Istanbul Airport, passengers can transfer to the airport metro line at Kağıthane station.

Sapphire stands apart from other Levent residences through its direct metro connection and the generous starting size of its units. Floor plans starting from 120 m² clearly differ from the area's supply of 60–80 m² studio-heavy residences and appeal to buyers seeking a permanent home. With a limited stock of 187 units, common area density remains low compared with projects of similar scale offering a thousand or more units.

The ecological double-skin façade absorbs external noise and climatic effects within a buffer zone, reducing the wind and noise issues commonly found on the upper floors of high-rise towers. Garden floors placed every three storeys are a rare application that brings open-space living into a vertical structure.
