Abstract
A modular building block characterized by a male-female fastener arrangement between successive layers of blocks, i.e. the blocks are positively positioned by a pattern of locking tabs cooperating with slots. Each modular building block is compartmentalized for receiving insulative material and space for utility passage. Provision is made for readily securing the modular blocks onto a conventional footing and/or foundation. Corners and block staggering between successive layers are effectively achieved through choosing the appropriate pattern presented by the aforesaid male-female fastener arrangement. The modular building blocks are rigid, yet light in weight, due to fabrication material selection.
