PURPOSE: A block for construction is provided to improve an exterior by forming desired patterns or drawings on the surface of the block. CONSTITUTION: A block(1) for construction is composed as follows. Irregularities(1a) are formed on the desired pattern parts or the opposite parts to the desired pattern parts on the top surface of the block to divide the top surface of the block into pattern parts and blank parts. The block is processed to have a rough surface. The rough surface of the block prevents slipping on a road.
