PURPOSE: To construct a block structure with a stacked stone pattern by use of a plurality of standardized unit blocks, as if stones are stacked respectively, by providing rugged edges so that adjacent units coincide with each other at a part or the whole parts of butt-joints, in a true stone stacking unit or a pseudo-stone pattern stacking unit.

CONSTITUTION: A stone-stacked pattern 2 made of a plurality of pseudo-stone patterns and same rugged edges 3 at the right and left sides and the upper and lower sides, which coincide with each other at the butt-joints of the adjacent units 1 are provided in the stone-stacked pattern units. Adjacent single units 1 are butt-jointed with each other to arrange a plurality of units to form a plane or a curved face. In this time, since the boundaries formed by butt-joints of the rugged edges 3 show the same line with the boundary lines formed by other stone-stacked patterns 2, respective shapes of the block structure with stone-stacked patterns are almost indistinguishable. In this way, a stone-stacked pattern which seems to be apparently random, can be made on the construction surface.
