A wall 21 is attached, and a second building unit 20 in which the other side surfaces on the long side are opposed to each other is disposed at the second rising portion 121 of the base 101. For example, as shown in FIG. 4, a ceiling 22 and a floor 23 are attached to the second building unit 20.
The lower ends of the second rising portions 121 are continuous with each other through the bottom portion 101 a of the base 101. It is preferable that the foundation 101 of the building is a solid foundation because the bottom portion 101a is continuous over all the rising portions (111, 121). Even if it is a cloth base, a concrete layer may be provided between the facing rising portions to be continuous.

As shown in FIG. 3 and FIG. 4, the wall 21 includes a panel plate 21 a, a longitudinal trunk edge 21 b, a gypsum board 21 c and the like, and has sound insulation. Moreover, the heat insulating material is provided between the panel board 21a and the gypsum board 21c.
The wall 21 is the same as the wall 11 of the first building unit 10, and the panel plate 21a is made of cellular concrete material such as PALC. Instead of the panel plate 21a made of PALC, the panel plate 21a made of ALC may be used, or a sound absorbing panel, a sound insulation panel or the like may be provided as the panel plate 21a to enhance the soundproofness.
Further, an opening (not shown) communicating the wall 21 and the wall 11 is provided as an entrance and exit of the soundproof room 1a, and a soundproof door or the like is provided at the opening.

It is intercepted by the air layer 130, and the sound can be prevented from leaking out.
Further, since the bottom portion 101a is provided between the opposing second rising portions 121, the sound passing through the floor 23 of the soundproof room 1a is blocked by the second rising portion 121 and the bottom portion 101a. , That sound can be prevented from leaking out.
Further, by interposing a joint material (backup material) having a large specific gravity, such as a D-type backer, between the second building unit 20 and the second rising portion 121, the airtight soundproofing can be improved.
Further, by filling the gap between the walls 21 of the second building unit 20 constituting the soundproof room 1a with the joint material having a large specific gravity, the air tightness can be further enhanced.

  In addition, a floor 41 having a flat material 41 b having sound insulation at a position facing the ceiling 12 of the first building unit 10 is attached to the upper floor unit 40 stacked on the first building unit 10 Therefore, the sound that has passed through the ceiling 22 of the soundproof room 1a is blocked by the floor 41 (planar material 41b), and the sound can be prevented from leaking out.

  Moreover, since the board | plate material 5 which has a sound insulation is provided in the ceiling 12 of the 1st building unit 10 along the position corresponding to the wall 21 of the 2nd building unit 20, the ceiling 22 of the soundproof room 1a The sound that has passed through is cut off by the plate 5 of the ceiling 12, and the sound can be prevented from leaking out.
