In prestigious locations on the Istanbul Bosphorus such as Bebek, Arnavutköy, Kuruçeşme and Ortaköy, the supply of new buildings is extremely limited.
For this reason, new or comprehensively renovated buildings on the Bosphorus line trade at a significant price premium compared with older buildings of similar location and view.
Depending on the district, view quality and construction standards, the new-build premium generally ranges between 20% and 50%, while in some ultra-luxury projects this rate can reach higher levels.
Compliance with earthquake regulations, parking, security, technical infrastructure and modern living amenities directly influence investor preferences.
Demand for new construction in Bosphorus-view yalı apartments and prestige residences in particular is strongly supported by international investors as well as domestic buyers.
The limited scope for new project development on the Bosphorus line, where the historic building stock is dense, further increases the value of existing new construction.
Family office structures and ultra-high-net-worth investors regard new-generation Bosphorus properties as an important part of their long-term wealth-protection strategies.
The new-build premium therefore reflects not only construction quality but also limited supply, global demand and future value-protection potential.
