PROBLEM TO BE SOLVED: To make it possible to easily execute the maintenance of wiring and piping provided to the under-floor section and ceiling plenum inside a building in a unit building, or to enable the use of the under-floor section and ceiling plenum as a storage space, etc. SOLUTION: Building units 11 and 12 are so constituted that floor beams 116 and 126, columns 111 and 121 and ceiling beams 116 and 126 are used as a frame. In that, case the lower end of the column 121 is projected downward by a fixed length from the lower surface level of the floor beam 126, or the upper end of the column 111 is projected upward by a fixed length from the upper surface level of the ceiling beam 115. The building unit 12 projecting the lower end of the column downward by a fixed length from the lower surface level of the floor beam 126 is laminated on the building unit 11 projecting the upper end of the column upward by a fixed length from the upper surface level of the ceiling beam 115 to construct a unit building. |
