Modular prefabricated building blocks

Abstract

A building block for a modular system for construction of a wall frame, the building block having a frame portion having: a rear exterior side; a front interior side; a top end; a bottom end; a left side; and a right side; a sheathing extending across the rear exterior side; at least a first dowel protrusion or at least a first dowel cutout; at least a first mortise; and at least a first tenon opposite to the at least a first mortise; such that the at a first mortise is capable of associating with a corresponding first tenon of a second building block to create a first mortise and tenon joint; and such that the at least a first tenon is capable of associating with a corresponding first mortise of a third building block to create a second mortise and tenon joint.

What is claimed is: 
     
         1 . A building block for a modular system for construction of a wall frame, the building block comprising:
 a frame portion having:
 a rear exterior side;
 a front interior side; 
 a top end; 
 a bottom end; 
 a left side; and 
 a right side; 
 
 a sheathing portion extending across the rear exterior side; 
   at least a first stud extending horizontally outwards from the frame portion on the front interior side, such that the first stud and the front interior side are perpendicular;   at least a first dowel protrusion or at least a first dowel cutout on the first stud on the top end;   at least a first mortise having a first mortise depth; and   at least a first tenon opposite to the first mortise;   such that the first mortise is capable of receiving a corresponding first tenon of a corresponding second building block to create a first mortise and tenon joint;   such that the first tenon is capable of being received into a corresponding first mortise of a third building block to create a second mortise and tenon joint; and   such that a first interior space is formed within the wall frame between the first stud and the front interior side.
