A stackable building wall (10) adapted to be stacked with a plurality of identical building wall units (12, 14, 16) in a plane to form a wall comprising three rectangular panels each including inner and outer faces, a pair of spaced apart long edges (20 and 22), and a pair of spaced apart shor t edges (24 and 26) joined to the short edges of the other two panels to form a triangle, stackable building wall units (12, 14, 16) which can be stacked wi th the exterior surfaces of the panels in a abutting relation. The exterior fac e of at least one of the panels includes a female recess (46) therein for receiving a complementally formed key to facilitate alignment and preclude relative shifting of the stacked units in a direction extending between said long edges.
