THREE-DIMENSIONAL STRUCTURE

PROBLEM TO BE SOLVED: To provide a three-dimensional structure for reducing construction cost, and advantageous to effectively using a space. SOLUTION: This three-dimensional structure 12 has seven stories and a vehicle traveling passage 14. The vehicle traveling passage 14 is arranged so as to connect a floor 20 of the respective stories to an external road. Two of an upward traveling passage 16 and a downward traveling passage 18 are arranged as the vehicle traveling passage 14. The vehicle traveling passage 14 spirally extends along a part positioned on the outermost side among the contours of the three-dimensional structure 12 in a plan view. The floor 20 extends up to the inside of the vehicle traveling passage 14 in a place for connecting the vehicle traveling passage 14 to the floor 20 in a plan view, and extends over the substantially whole area of a part except for the vehicle traveling passage 14, by extending up to the most outside of the contours of the three-dimensional structure 12 in a plan view, in a place for not positioning the vehicle traveling passage 14.
