A rectangular cabin dwelling structure, comprising:
- a flat level foundation slab;
- a predefined bolt array including a plurality of spaced-apart vertically aligned threaded bolts having a diameter and which are embedded and secured in said foundation slab, said bolt array defining an exterior frame having a plurality of corners and an enclosed interior;
- a plurality of beam segments, each of said plurality of beam segments having an inner surface and a flat top surface and a parallel flat bottom surface adapted to abut flushly against a top and a bottom surface of vertically adjacent ones of said plurality of beam segments, each of the plurality of beam segments extending lengthwise between opposite beam ends, each of said plurality of beam segments further including spaced-apart bolt bores extending vertically therethrough, said bolt bores corresponding to spacing of said spaced-apart vertically aligned threaded bolts in said bolt array and which said bolt bores have a diameter exceeding a diameter of said threaded bolts, where the parallel flat top surfaces and flat bottom surfaces of the multiplicity of beam segments extend along an entire length of each of the plurality of beam segments between the beam ends, each beam end terminating at flat planar surfaces perpendicular to and extending between the flat top surfaces and the flat bottom surfaces;
- and
- securing nuts for mating with said vertically aligned threaded bolts and washers for said securing nuts;
- wherein
- said plurality of beam segments are vertically stacked in layers with corresponding ones of said vertical bolts extending through corresponding bolt bores in each said beam segment to form one or more vertical walls, each of the vertical walls including an uppermost beam segment of said plurality of beam segments having at least one vertically-oriented side and a top;
- said washers having a horizontal extent exceeding the diameters of said respective bolt bores such that when said securing nuts are tightened said washers apply pressure to force said layers together;
- and
- wherein multiple ones of said vertical walls meet to form one or more of said corners;
- wherein said layers of beam segments include alternating odd layers and even layers;
- said layers of beam segments include ones of said beam segments identified as cross beams and transverse beams, each of the beam segments having an end;
- at each of said one or more corners said bolt array includes one of said vertical bolts designated as a corner bolt;
- at a corner of each odd layer said cross beam extends across said corner, and said corner bolt extends through said cross beam, while the end of said transverse beam abuts flush against an inside of said cross beam;
- and
- at a corner of each even layer said transverse beam extends across said corner, and said corner bolt extends through said transverse beam while the end of said cross beam abuts flush against an inside of said transverse beam;
- wherein at each said layer in each said corner, each of said corner bolts passes alternately through one of said cross beams or one of said transverse beams.
