A multilevel spiral incremental structure and construction method for residential and/or commercial buildings is disclosed. The present structure is constructed using a plurality of prefabricated modular units or pods which are substantially similar in their size and configuration and assembled symmetrically about a central core designed to contain ductwork, conduit, vents, pipes and other utility apparatus. The pods are supported on stepped foundation piers at progressively higher elevations based upon a calculated vertical increment factor. In a preferred embodiment six pods are arranged about a central core to produce a hexagonal structure resulting in a vertical increase of about ten feet or one story in floor elevation per revolution about the core. The present construction may be cost effectively expanded into a multilevel building by adding new pods after the initial construction phase without digging a new foundation or demolishing portions of the original structure.
) A spiral incremental structure comprising:
) The spiral incremental construction of claim 1 wherein said vertical increment factor is calculated to produce a predetermined increase in vertical elevation per revolution about said core structure
) The spiral incremental structure of claim 2 wherein said vertical increment is in the range of 19.5 to 21.5 inches.
) The spiral incremental structure of claim 1 wherein said pod structures are prefabricated modules including a floor assembly, radial wall assemblies, an exterior wall assembly, and a roof assembly.
) The spiral incremental structure of claim 4 wherein said pod structures are generally diamond-shaped in configuration such that said radial wall assemblies within each pod structure define an included angle of 60 degrees.
) The spiral incremental structure of claim 5 wherein adjacent pod structures are interconnected by removable fastening means.
) The spiral incremental structure of claim 2 wherein the outer periphery of said structure is hexagonal in configuration.
) The spiral incremental structure of claim 7 wherein said core structure is hexagonal in configuration.
) The spiral incremental structure of claim I wherein said supporting means includes a stepped foundation wall disposed beneath and extending about the periphery of said spiral incremental structure to support said pod structures at said progressively higher elevations.
) The spiral incremental structure of claim 9 wherein said supporting means further includes plurality of support columns disposed at predetermined locations conforming to said radially symmetrical pattern and being constructed to said progressively higher elevations to provide support for said pod structures.
) A spiral incremental structure comprising:
) The spiral incremental construction of claim 11 wherein said vertical increment factor is calculated to produce a predetermined increase in vertical elevation per revolution about said core structure
) The spiral incremental structure of claim 12 wherein said vertical increment factor is in the range of 19.5 to 21.5 inches.
) The spiral incremental structure of claim 11 wherein said pod structures are prefabricated modules including a floor assembly, radial wall assemblies, an exterior wall assembly, and a roof assembly.
) The spiral incremental structure of claim 14 wherein said pod structures are generally diamond-shaped in configuration such that said radial wall assemblies within each pod structure define an included angle of 60 degrees.
) The spiral incremental structure of claim 15 wherein adjacent pod structures are interconnected by removable fastening means.
) The spiral incremental structure of claim 12 wherein the outer periphery of said structure is hexagonal in configuration.
) The spiral incremental structure of claim 17 wherein said core structure is hexagonal in configuration.
) A method of constructing a multilevel spiral incremental structure, said method comprising the steps of:
) The method of claim 19 further including the step of:
