A building block may be designed to hold utilities, including but not limited to, electricity and plumbing. Such a building block can resist compression forces and moment and can connect to other building blocks to form a modular wall system with the ability to distribute the forces in a way that reduces the stresses on each individual block. The building block may include a body with an upper end and a lower end, one or more main compartments, and one or more inner pass-through openings, wherein the upper end includes one or more protrusions, and the lower end comprises one or more intrusions and one or more slots. A building system may include more than one such building blocks and a base.

A insulated masonry wall system having insulation blocks between structural and face blocks to provide structures that are strong, inexpensive, avoid thermal bridges, and resist transmission of heat. The walls are attractive and versatile, and an enormous variety of decorative face members may be utilized. The face blocks are attached to the structural blocks to prevent facing materials from falling even if fire destroys the insulation blocks between the structural blocks and the facing. The system resists water penetration and effectively drains water that does penetrate any portion of the system.

A modular block with four walls, a top face and two internal cavities, where both the locking and the centralization between the blocks are prominently made by male and female wedge-like couplings.
