PROBLEM TO BE SOLVED: To enhance degree of freedom of an earthen floor layout, even in an area projecting over a part where a column cannot be installed, by improving stability of the area.SOLUTION: An earthen floor structure has an earthen floor (vestibule earthen floor 308) formed after removing a part of floor beams (longer-side floor beams 301a, 301b) of a pair of adjacent building units 300A, 300B, over the pair of adjacent building units 300A, 300B at the removed part. A projected area 310 is formed at one of the pair of building units 300a, 300B, the projected area projecting inward of the partially removed floor beam (longer-side floor beam 301a) and along a contour of the earthen floor. A peripheral edge of the projected area 310 is supported from below by an earth retaining wall 360 surrounding the earthen floor.SELECTED DRAWING: Figure 2 |
