PROBLEM TO BE SOLVED: To promote communication within a building by effectively utilizing a staircase part.SOLUTION: A building includes: a staircase part 7 that has a staircase 7a communicating with upper and lower floors; a passage part 8 that adjoins the staircase part 7 in the state of spatially continuing into the staircase part; a habitable room part 2 that adjoins both or either of the staircase part 7 and the passage part 8; a fireproof cutoff part S that isolates the staircase part 7 and the passage part 8 from a space around them in the state of surrounding them in case of fire; and a pressurization mechanism that applies pressure to an internal space of the fireproof cutoff part S so that the internal space becomes higher in pressure than a space around it in case of fire.SELECTED DRAWING: Figure 1 |
