Mustafa Kemal Atatürk Cultural Center | not Mimarlık, in Dikili, İzmir, Turkey, is a cultural project credited to Not Mimarlık (2023). It is exactly the kind of building where a stone choice is meant to still look correct in fifty years, which makes the specification worth studying. 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.
Public documentation for this particular project does not break down the stone specification by room or surface — which happens more often than you would think, even for well-photographed buildings.
For sivrihisar, eskişehir, turkey, we cannot verify the exact material from the public record, so as a general reference point we would point to Breccia Oniciata.
We are not the right place to see this project's photography — that credit belongs at the source link below.
