We came across Vi̇lla p | Ofis mpu in Kayseri while going through an independently compiled archive of Turkish architecture. The project is credited to Ofis MPU, and dates to 2019. 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 beige slate | i̇zmi̇r, bayindir, we cannot verify the exact material from the public record, so as a general reference point we would point to Calacatta Oro.
The original project write-up, with full photography and credits, is linked below — we do not reproduce it here, only the facts.
