Claim 17:
18. A method for assembling a building, the method comprising:
providing a first building module, the first building module having:
a first lower horizontal support structure attached to a bottom of the first building module;
a first upper horizontal support structure attached to a top of the first building module; and
a vertical support connecting the first lower horizontal support structure to the first upper horizontal support structure;

connecting a first connecting nut to the first lower horizontal support structure;
attaching a support rod to a top side of the first connecting nut, the support rod being at least partially disposed within the vertical support;
connecting a second connecting nut to a top end of the support rod, the second connecting nut having a flange that interfaces with a top side of the first upper horizontal support structure;
connecting a spacer on top of the first upper horizontal support structure;
placing a second building module on top of the first building module such that a second lower horizontal support structure of the second building module rests on top of the spacer, wherein the spacer is sized and shaped to fit between the top of the first upper horizontal support structure and a bottom of the second lower horizontal support structure, and wherein the spacer rests on top of and interfaces with the flange of the second connecting nut as well as the top of the first upper horizontal support structure, thereby interlocking the second connecting nut between the first upper horizontal support structure and the spacer; and
wherein the support rod spans a distance between the first lower horizontal support structure and the second lower horizontal support structure.
