Bozanoglu Stables, in Çatalca / İstanbul, was designed by an uncredited studio. It is one of the wider set of Turkish architecture projects we have been cataloguing for what they reveal about real-world stone specification. To be clear: this is not a DIJA project, and we did not supply the material — it is included here purely as a documented reference.
The archive credits the architect and the build, but stops short of naming the specific stones used — not unusual for a project this size.
With no documented stone type to go on, a few general suggestions from our own range that would suit a project of this kind: Calacatta Oro.
The architect's own account, and the photography that goes with it, is one click away at the source link.
