Further, as shown in FIG. 1, the dormer 14 is provided with a front wall 20 that continues from its side wall. A space 22 is formed between the front wall 20 and the roof 16. As will be described later, a window such as a sash window may be disposed in the space portion 22, or no space may be formed.
[0015]
In the present embodiment, as can be understood from FIG. 2, the front wall 20 is formed in the same plane as the front wall 21 of the main body of the log house 10. By adopting such a structure, the strength of the dormer can be increased. For example, it is also possible to arrange a reinforcing column that extends from the back of the front wall 21 of the main body through the roof 16 to the back of the front wall 20 of the dormer (or further to the lower surface or beam of the roof 16). The main body of the log house 10 in which the dormer 14 according to the present embodiment is formed will be briefly described. In the present embodiment, the log house 10 is formed with a first floor portion (see the reference symbol F1) and a second floor portion (see the reference symbol F2). The first floor portion has a height of approximately 2.5 m, and the second floor portion has a height of approximately 2 m up to the floor slab of the third floor portion described later. Accordingly, both the first floor part and the second floor part have a sufficient height for the residents to be active. Further, in the dormer 14, the space below the floor slab 24 of the third floor portion (see reference numeral 26) can be used as the second floor portion. Furthermore, in the present embodiment, a height of about 2 m is also secured for the space inside the dormer 14.

In 1st Embodiment, the bathtub is arrange | positioned in this domer so that it can utilize as an open-air bath. More specifically, as shown in FIG. 5, a bathroom 30 is made in the dormer 30, and the floor slab 24 is subjected to waterproofing treatment using, for example, a sheet and a bathtub 32 is arranged. Yes.
In the present embodiment, a sash window 22 is provided between the front wall 20 and the lower surface of the roof 14. A back wall 34 is formed on the back side of the dormer. Accordingly, the bathroom 30 is defined by the front wall 20, the side walls 18, 18 and the back wall 34.
[0018]
The height from the upper surface of the floor slab 24 to the upper end of the front wall 20 is set to about 80 cm. That is, the distance from the floor slab on the first floor to the upper end of the front wall is about 5.2 m. Therefore, when the resident is taking a bath, he / she was built at the same level even when approaching in a standing posture inside the front wall 20 to see the outside scenery through the sash window 22 Even if another person looks at the bathroom side of the log house 10 from the second floor of the log house or house, only the face of the resident can be seen. Therefore, the resident can enjoy bathing without worrying about other people's eyes. By keeping the above 80 cm, bathers can enjoy the outside scenery well in the state where they enter well. If the privacy on the bathroom side is more securely protected, the above-mentioned 120 cm may be used.
[0019]
Moreover, as can be understood from FIG. 5, the space 26 below the third floor portion (that is, the bathroom 30) secured by the dormer is an enlarged portion of the second floor portion. In the present embodiment, due to the large roof 12, the height from the floor to the ceiling becomes lower in the second floor portion as it approaches the front and rear edges. However, in the space 26 below the dormer, the height of the ceiling can be secured constant. This makes it possible to secure a wider living space on the second floor.
[0020]
In the first embodiment, the roof 14 is formed using a slate or the like in the same manner as the large roof 12, but in the second embodiment, partially openable and closable glass is used. . FIG. 6 is a perspective view of a log house including the dormer 100 according to the second embodiment. In the second embodiment, the same members as those in the first embodiment are denoted by the same reference numerals.
