Us Embassy Building in Ankara is a civic building in Ankara, from 2023, credited to Ennead Architects. Institutional buildings like this one tend to specify stone conservatively, favoring longevity and a certain formality over anything experimental. 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 architects credited these specific applications: exterior walls: travertine classic / deni̇zli̇; exterior walls: travertine silver / deni̇zli̇; interior floor and walls: dark olive marble / si̇vas.
For travertine classic / deni̇zli̇, the specified stone is one we stock directly: Travertine Classic Beige. For travertine silver / deni̇zli̇, this is a straightforward match — we sell the same material: Travertine Silver Veincut. For dark olive marble / si̇vas, the specified stone is one we stock directly: Sivas White.
