The goal of this invention is reducing the basic material needed without reducing the strength of the construction. It is reached by reducing the dimension and the thickness of the batako. This will be easier for the mason’s work. The design development of the batako’s shape was expected to increase the aesthetical value and to follow its function: decreasing the temperature of the walls, because the walls will have some gaps where the air can flow through them.
