Özer\Ürger Architecture's Kocaeli Walking Path Urban Design Project in Kocaeli (2022) is a public realm or urban design project. Squares, parks, and walking paths are where a stone's real-world weather resistance gets tested, not just its polish. 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 published record specifies the following material use: flooring: nero nebiyan granite / samsun; flooring: fossil rustic green marble / safranbolu.
For nero nebiyan granite / samsun, the closest match in our own catalogue is Black Galaxy Granite. For fossil rustic green marble / safranbolu, the specified stone is one we stock directly: Onyx Green.
The original project write-up, with full photography and credits, is linked below — we do not reproduce it here, only the facts.
