TURKCELL Headquarters Kucukyali

Turkcell’s 37,500 m², LEED Platinum–certified headquarters in Küçükyalı/Maltepe was conceived with a single, human-focused lighting language across public areas, open offices, meeting rooms, and circulation. Custom micro-prismatic luminaires integrated into the circular ceiling system—supported by daylight sensing and DALI control—deliver balanced 4000K illumination (300–500 lx on work surfaces) while subtly highlighting key social zones and terraces with low-glare accents.
