Incorporated in April 2011. Business registration no. 142-81-36228. We own and run our factory and stone yard at 196-4 Maejari-gil, Gwangju-si.
We hold a specialty construction license for stonework, so we take responsibility from supplying the stone to installing it.

Our yard is full of slabs and tiles. You can see the actual slab before it is cut, and we check your drawings before we quote.
