Description

  The present invention relates to a structure under a staircase for effectively using a lower space of a straight staircase disposed in a room of a house.

  2. Description of the Related Art Conventionally, a proposal has been made that a lower space of a straight staircase arranged in a room of a house is covered with a wall or joinery and used as a storage space (see, for example, Patent Document 1). However, in a particularly small room, when the lower space of the straight staircase is used as a storage space, there is a problem that the living space in the room is reduced by that amount, giving a tight feeling and a feeling of pressure.

  On the other hand, the space below the straight staircase placed in the interior of the house is opened without being covered by walls and fittings, and is used as part of the living space by being integrated with the living space in the room. Things are also done on a daily basis. However, the small space located below the straight staircase in the lower half of the straight staircase is particularly difficult to use as a living space due to its low height and narrowness. Since it is easy to hit, there is a problem that it is not suitable for use as a storage space and easily becomes a dead space.
