Abstract: A transportable prefabricated container house includes a main body and a house forming body, configured to be housed in the main body and drawn out of the main body at the installation site to be expanded/assembled into a house threefold the size of the main body. Assembly of the pre-assembled square “U”-shape walls sandwiched between the floor and ceiling boards includes tightly tying the ceiling supporting beams and the floor supporting beams together with shackles, and passing steel rods or pipes between the walls to render the house immune from earthquakes and hurricanes. A foundation of steel pipe bodies assists earthquake- and hurricane-resistance. Mega structures housing multitudes of container houses can be used when stacking two or more container houses is insufficient and large scale urban development is necessary, and are capable of resisting earthquakes and hurricanes due to a system of wire mesh covering.

Abstract: Portable turntables or rotation platforms built by assembly enable rotation of vehicles and/or loads of significant size and/or weight. The portable turntables or rotation platforms are highly effective and efficient with respect to materials, construction and environmental impact.

Abstract: Building by assembly structures and paths enable protection from and withstand time, natural and man-made damage. The structures and paths are highly effective and efficient with respect to materials, construction and environmental impact.

Abstract: A prefabricated container house includes a container type main frame member when on a chassis capable of being pulled by a trailer truck; and dwelling forming members which can be housed in the main frame member, and which can be drawn out of the main frame member at an installation site, and assembled into a house.
