The structure in which the underside surface 5A of the overhang 5, the ceiling 9 of the first room 8, and the upper end 31B of the first opening 31 are located at the same height is referred to as a flat-ceiling structure. In the flat-ceiling structure, the ceiling 9 of the first room 8 is connected to the underside surface 5A of the overhang 5 in a continuous manner, so that the first room 8 seems to extend to the exterior. When the window 18 of the first opening 31 is open, the ceiling 9 of the first room 8 is continuous with the underside surface 5A of the overhang 5.

The operation of the present embodiment will now be described.

Utilization of a space near the window side is limited. In an example, a house plant is arranged near the window side. In an example, a table is arranged near the window side, and an object is arranged on the table. The space near the window side is less likely to be used directly by a person. In an example, a person may lean on the window 18 and read a book. A person does not often actively use the space near the window.

In the present embodiment, the height of the second floor portion 22 is set to allow a person to sit facing the interior and to sit facing the exterior. This facilitates the use of the space near the first opening 31. A person may sit or lie down on the second floor portion 22. The second floor portion 22 also serves as a place on which an animal lies. A person may place an object on the second floor portion 22 and temporarily place laundry or purchased food. A person may place a house plant, an ornament, and a lifestyle item on the second floor portion 22. The person may sit on the second floor portion 22 facing the exterior to relax while viewing the garden or scenery. Without arranging a chair or the like on the third floor portion 23, the person may casually relax while viewing outside. When a table is placed on the third floor portion 23, the person may sit on the second floor portion 22 and have a meal or read a book. The second floor portion 22 may serve as a chair placed on the third floor portion 23. Thus, the area of the third floor portion 23 is utilized effectively. The second floor portion 22 allows the space near the window to be used for various purposes.

The present embodiment has the following advantages.
