A lightweight, hollow building block is disclosed. The building block preferably has a rectangular base and an open pentagonal top. Two adjacent sides of the block form right angles with the base and the top. The three remaining adjacent sides are inclined outwardly from the base at an angle which permits the blocks to be stacked one inside another. When four such blocks are arranged in a double-wide and double-long pattern, they form a rectangular, vertical sided building unit. A building is constructed from the blocks by laying a course at the time and preferably filling the open, upturned blocks in each course with some locally available filler material to lend weight and stability to the structure.

A hollow stackable building block having side walls with parallel spaced-apart top and bottom edges which respectively define the perimeters of a base plane and a top plane of the block, wherein the base plane of the block is rectangular and the top plane of the block is pentagonal, the side walls of the block comprising: a trapezoidal side wall which is perpendicular to the base plane of the block, having a square end and an opposite end which is inclined away from the square end at an obtuse angle with respect to the bottom edge of said side wall; a trapezoidal end wall which is perpendicular to the base plane and continuous on one end with the square end of the trapezoidal side walls, an opposite end being inclined away from the one end at an obtuse angle with respect to the bottom edge of the end wall; a rectangular side wall which is continuous with the inclined end of the trapezoidal side wall and thereby inclined at an angle with respect to the base plane of the block; a rectangular end wall which is continuous with the inclined end of the trapezoidal side wall and thereby inclined at an angle with respect tot he base plane of the block; and a triangular side wall disposed between and respectively continuous with the adjacent ends of the rectangular side wall and the rectangular end wall.
