a plurality of support walls, wherein the plurality of support walls are attached to the core wall structure and cantilever from the core wall structure; a plurality of floor structures arranged vertically and attached to the core wall structure, wherein each floor structure is supported from below by a first set of the plurality of support walls and from above by a second set of the plurality of support walls, a position of the second set of the plurality of support walls being radially offset from a position of the first set of the plurality of support walls; and a plurality of openings in the core wall, wherein at least one opening is provided between any two successive floor structures of the plurality of floor structures, and wherein alternating openings in a vertical direction are arranged to align along an angle of vertical offset. ### Claim 2 (depends on 1) The structure according to claim 1, wherein adjacent openings in a vertical direction are circumferentially offset approximately equally to the offset between the positions of the first set and the second set of the plurality of support walls. ### Claim 3 (depends on 1) The structure according to claim 1, wherein one or more of the plurality of support walls are of a differing length. ### Claim 4 (depends on 1) The structure according to claim 1, further comprising: linking beams used to join a radial perimeter portion of successive floor structures of the plurality of floor structures. ### Claim 5 (depends on 1) The structure according to claim 1, each of the plurality of floor structures having a long span, further comprising: an edge beam, wherein the edge beam provides additional support to the long span of at least one of the plurality of floor structures. ### Claim 6 (depends on 1) The structure according to claim 1, wherein each successive floor structure of the plurality of floor structures in the vertical direction is radially offset from the preceding one of the plurality of floor structures. ### Claim 7 (depends on 1) The structure according to claim 1, wherein each floor structure of the plurality of floor structures is configured to be in the shape of a tear-drop. ### Claim 8 (depends on 1) The structure according to claim 1, wherein each floor structure of the plurality of floor structures is configured to be in the shape of a pentagon. ### Claim 9 (depends on 1) The structure according to claim 1, wherein each floor structure of the plurality of floor structures is configured to be in the shape of an almond. ### Claim 10 (depends on 1) The structure according to claim 1, wherein the central core is circular in dimension. ### Claim 11 (depends on 10) The structure according to claim 10, wherein an elevator is provided to move within an interior portion of the central core. ### Claim 12 A method of building a twisting structure, comprising: constructing a central core; building a plurality of cantilever walls connected to the central core; constructing a plurality of floor structures arranged concentrically in a vertical fashion about the central core, wherein each floor structure of the plurality of floor structures is supported from above by a first set of the plurality of cantilever walls and is supported from below by a second set of the plurality of cantilever walls, wherein the first set of the plurality of cantilever walls attach to the floor structure at a position radially offset from a position where the second set of the plurality of cantilever walls attach to the floor structure; and providing a plurality of openings in the core wall, wherein at least one opening is provided between any two successive floor structures of the plurality of floor structures, and wherein alternating openings in a vertical direction are arranged to align along an angle of vertical offset. ### Claim 13 (depends on 12) The method of building a twisting structure of claim 12, wherein adjacent openings in a vertical direction are circumferentially offset approximately equally to the offset between the positions of the first set and the second set of the plurality of cantilever walls. ### Claim 14 (depends on 12) The method of building a twisting structure of claim 12, wherein one or more of the plurality of cantilever walls are constructed to be of a different length. ### Claim 15 (depends on 12) The method of building a twisting structure of claim 12, wherein each successive floor structure of the plurality of floor structures in the vertical direction is constructed to be radially offset from the preceding floor structure of the plurality of floor structures below. ### Claim at position 16 16-18.
