PROBLEM TO BE SOLVED: To provide a tent house that can expose and make visible ground surface in a usually closed and dead space area in the tent house by making skeleton frames for the tent house movable. SOLUTION: This tent house 10 comprises a pair of rail parts 11, a plurality of skeleton frames 12 that rise up from the rail parts 11 and stand astride between them, casters (sliding members) set to both ends of these skeleton frames 12 (on the rail parts) and a covering material 15 that covers the outside of the individual skeleton frames 12 and can form a closed and dead space S. Each caster 14 is arranged so that it may be movable along the rail part 11 for each skeleton frame 12. Individual skeleton frames 12 can vary the size of the closed and dead space area S by adjusting mutual intervals between them.
