A building block (10) of the type which can be used to construct a structure made up of a number of identical such blocks disposed side to side. The blocks are usually square although triangular blocks may be used in conjunction therewith. The preferred form of the square block is provided with four flat sides including parallel first (14) and second (18) sides and parallel third (16) and fourth (12) sides. Two flanges (42, 40) extend along the respective first and third sides, projecting outwardly therefrom. Two recesses (60, 49) shaped complementarily to the flanges extend along the respective second and fourth sides, projecting inwardly therefrom. The first flange intersects the second flange adjacent the junction between the first side and the third side. At their opposite ends the flanges comprise triangular portions (54, 66) which span the respective recesses and are provided with indentations in their outer faces which are aligned with the recesses. Adjacent the junction (20) between the second side and the fourth side, the recesses intersect and comprise a common indentation (70) which receives the indented triangular portions of the flanges of adjacent blocks in the structure. The form of the blocks ensures that all interfaces between blocks laid adjacent one another in a structure are covered by the flanges. For a wall structure, the blocks are preferably laid with the sides at 45.degree. to the horizontal. Blocks of polygonal shapes are also envisaged.
