Claim:
A modular building system comprising: a foundation; a plurality of elongate, generally horizontally arranged beams, each beam including an outer shell portion and a distinct thermal insulating substance contained within said shell portion, said beams being stacked in substantial alignment with one another and interlocked to define a wall, said beams being interlocked such that said beams are restricted in moving vertically, as well as horizontally in both longitudinal and lateral directions, relative to one another; and a vertical interlocking assembly including a plurality of elongate, generally vertically arranged rods, each rod disposed through a respective series of aligned holes in said stacked beams, each rod having a lower portion fixed to said foundation and an upper portion carrying a threaded connector that operably interengages an upper horizontal surface of said stacked beams, said threaded connector being selectively tightened to exert a laterally compressive and vertically interlocking force upon said stacked beams in said wall.
