De Opkamer has sourced 400 m2 of old 'Doornikse schorren', old Belgian blue stone floors. In Belgium these antique floors are often called old blue stone floors or old bluestone slabs. The old blue stone floors are characterized by their beautiful subtle color and the worn surface with countless imperfections. The original old floors can be recognized by the thickness and edges. The original thicknesses of these tiles are about 10 cm to 15 cm thick, but we can cut them back to 3 cm.
