The ceiling and walls are made of mortar finished with a metal trowel just like the exterior walls. A large steel door in matte black made with industrial parts divides this minimal space into halves.

Overall, the gallery has a plain yet contemporary atmosphere created by a simple combination of such characteristic materials as steel, mortar, and black mortar, mixed with the modern material of epoxy resin.
