An underground construction has: a circumference wall forming therein a cone shaped space; plural support members located at the circumference of the cone shaped space at vertically the same height; floor construction bodies each having plural bed beams and a floor portion, the ends of the bed beams being supported by the support members, and the floor portions being disposed in the middle of the cone shaped space at a fixed interval from the circumference wall.
No pillars for supporting the floors are needed, thereby leaving a maximum clear space on the floors for use.
