TEĞET designed Türkiye İş Bankası Painting and Sculpture Museum, a museum or cultural venue. These projects tend to specify stone the way archives specify paper — for permanence, not trend. 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.
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, Travertine Classic Beige, Nero Marquina.
The original project write-up, with full photography and credits, is linked below — we do not reproduce it here, only the facts.
