A floor assembly of a modular home includes a frame including a plurality of floor joists, at least one upper plate coupled to a top of the frame, a skid plate coupled to a bottom of the frame, the skid plate including a circular opening, and a pin socket including a cylindrical pipe section positioned around the circular opening. The pin socket is configured to receive a rotation pin and configured to cause the rotation of the floor assembly about the rotation pin when a force is applied to the floor assembly.

A modular home includes a space inside the modular home. The modular home includes a floor assembly including a frame comprising a plurality of floor joists, at least one upper plate coupled to a top of the frame; and at least one lower plate coupled to a bottom of the frame. The modular home includes a bladder tank support assembly coupled to the floor assembly. The bladder tank support assembly includes a support platform configured to be lowered from an upper position in which the support platform is received within the opening to a lower position below the floor assembly. The modular home includes an inflatable bladder tank positioned on the support platform, the inflatable bladder tank structured to fit between the support platform and the floor of the space when the inflatable bladder tank is deflated and the support platform is in the upper position.

A floor assembly of a modular home includes a frame including a plurality of floor joists, at least one upper plate coupled to a top of the frame, a skid plate coupled to a bottom of the frame, the skid plate including a circular opening, and a pin socket including a cylindrical pipe section positioned around the circular opening. The pin socket is configured to receive a rotation pin and configured to cause the rotation of the floor assembly about the rotation pin when a force is applied to the floor assembly.

A trailer configured to transport a load includes a bed including an upper surface configured to support the load, a slot positioned in the bed and extending from a front portion of the bed to a rear portion of the bed, and a first rotation pin configured to translate within the slot and extending from within the slot to above the upper surface of the bed.

A method of unloading a modular home from a trailer includes extending a plurality of linear actuators coupled to overhanging portions of a modular home positioned on a bed of a trailer until the linear actuators lift the modular home off of the trailer, sending instructions to one or more crawlers to move under the modular home, retracting the linear actuators to lower the modular home such that a lower surface of the modular home rests on a platform positioned on each of the crawlers, sending instructions to the crawlers to move the modular home to an installation location, extending the linear actuators until the linear actuators lift the modular home off of the crawlers, sending instructions to the crawlers to move out from under the modular home, and retracting the linear actuators to lower the modular home to an installed height.

A method of constructing a building is disclosed, including selecting a standard dimension less than a wide-load trucking permit limit and designing a building on a grid defined by the selected standard dimension. The building includes a plurality of prefabricated elements, wherein each prefabricated element has a width correspond to the selected standard dimension. The plurality of prefabricated elements includes a wall panel, a roof panel, a laterally resistive frame, and a rebar cage. The method includes fabricating each of the plurality of prefabricated elements at a manufacturing plant and transporting the elements by truck to a building site. The method includes constructing intersecting grade beam footings at the building site and pouring a slab between the intersecting grade beam footings. The grade beam footings include the rebar cage and have a uniform width and depth, the grade beam footings and the slab having contiguous upper surfaces.

A method of unloading a modular home from a trailer includes positioning a modular home on a trailer bed. The modular home includes a first housing portion having a first vertical edge coupled to a second vertical edge of a second housing portion by a hinge, and the first and second housing portions are arranged longitudinally on the trailer. The method further includes rotating the first and second housing portions about the hinge such that the first and second housing portions overhang from the sides of the bed, forming first and second overhanging portions. The method further includes coupling at least one of (1) a first horizontal edge of the first housing portion to a second horizontal edge of the second housing portion, or (2) a third vertical edge of the first housing portion to a fourth vertical edge of the second housing portion upon completion of the rotating.
