The invention relates to the industry of building materials, in particular to building blocks of layer-like structure.The multilayer building block (1) consists of a heat-insulating layer (3) of foam concrete and exterior layers (2) forming the stretching surfaces of the block, made of ultrastrong concrete with voids between the granules of the coarse aggregate. The exterior layers (2) of the block are made with prominences (4), directed inward the block, at the same time the prominences (4) of the layer of one of the stretching surfaces are placed between the prominences (4) of the opposite layer of another stretching surface.
