Hacettepe University Museum and Center for Biodiversity, in Ankara, is a cultural project credited to Erkal Mimarlık (2013-2014). 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.
The architects credited these specific applications: facade: limra stone, quarry: yozgat, şefaatli̇.
For limra stone, quarry: yozgat, şefaatli̇, the specified stone is one we stock directly: Limra Limestone.
The original project write-up, with full photography and credits, is linked below — we do not reproduce it here, only the facts.
