ABSTRACT:
An autofitting building block has two opposing side surfaces, two opposing end surfaces, a top surface and a bottom surface. The top surface has a plurality of dihedral projections which mate with a plurality of dihedral recessions on the bottom surface. The bottom surface has at least one more recession than does the top surface so that a channel is formed between two stacked bricks. Grooves are preferably placed in the end walls which form vertical channels which communicate with the hozizontal passages. A wall made of such bricks is also disclosed. The blocks can be either solid or hollow, and special blocks can be used for the corners and for the ends of the wall.
