[Action]
Next, operation of the first embodiment will be described.

In the unit building 10 shown in FIG. 4(A), an opening 38 is formed in the wall member 36 . In addition, the third indoor space 35 is not provided with an article that completely blocks the line of sight of the occupant. Thereby, in the unit building 10, the second indoor space 33 can be visually recognized from the first indoor space 26 through the third indoor space 35. As shown in FIG. In other words, the situation inside the first shed unit 32 can be grasped from the building unit 24 .

For example, by looking up at the mother PM in the first indoor space 26 , it is possible to grasp the state of the child PC in the vicinity of the opening 38 . Alternatively, after an earthquake occurs, the mother PM in the first indoor space 26 can check whether articles such as bookshelves have fallen down in the second indoor space 33 by looking up.

Further, as shown in FIG. 4B, in the unit building 10, the second indoor space 33 and the fourth indoor space 31 are connected. Therefore, for example, even if the child PC cannot speak, the father PF in the fourth indoor space 31 looks at the second indoor space 33 and speaks out, so that the child PC is in the first indoor space 26. The mother PM can grasp the state of the child PC.

When the child PC grows up and becomes difficult to live in the first shed unit 32, the first shed unit 32 is used, for example, as a storage room for articles. In this case, by visually recognizing a part of the articles stored in the first shed unit 32 from the first indoor space 26, the state of the articles can be grasped.

In the unit building 10 shown in FIGS. 4A and 4B, the first shed unit 32 and the second shed unit 34 are constructed as different units. For this reason, if only the first shed unit 32 and the second shed unit 34 do not fall under the oblique line restrictions of the Building Standards Law, only the first shed unit 32 is set to a height that satisfies the oblique line restrictions. units. In other words, it is possible to configure the second shed unit 34 with another unit higher in height than the first shed unit 32 . As a result, it is possible to prevent the height of the second shed unit 34 from being lowered unnecessarily.

In addition, in the unit building 10 shown in FIG. 4(B), the second indoor space 33 is brightened by daylighting because the outer opening 32E is formed in the first shed unit 32 . In addition, since the outer opening 34E is formed in the second shed unit 34, the third indoor space 35 is brightened by daylighting. This makes it easier to grasp the situation inside the first shed unit 32 from the building unit 24 . Furthermore, there is a case where the light received by either the outer opening portion 32E or the outer opening portion 34E is incident on the other side through the opening portion 38 . Therefore, even if trees (not shown) grow outside the first shed unit 32 or the second shed unit 34, the second indoor space 33 or the third indoor space 35 can be brightened.
