Abstract

(57) [Abstract] [Problem] Although the floor area is not included in the calculation of the floor area ratio, by obtaining an area that can be practically used for living for the occupants, it is possible to obtain an atrium structure while effectively utilizing the floor area ratio. It is assumed that. SOLUTION: In a maisonette type apartment house, a part of a ceiling of a lower floor 1 is made into an atrium 2, and the atrium 2 is closed at an appropriate height position of an upper floor 4 to form a loft 9. The ceiling height of the loft 9 is preferably a ceiling height that is not included in the floor area in the calculation of the floor area ratio.

Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 This invention relates to a stairwell structure in a maisonette-type apartment house.

[0002]

[Prior art]

 In recent years, condominiums have also been required to have spacious living spaces with atrium structures. A maisonette-type dwelling unit can easily have a stairwell structure, but if it is a stairwell structure, the floor area of the upper floor will be narrow only in the stairwell. In the design of a multi-family house, it is required to obtain a floor area as large as possible, and the atrium structure conflicts with such a demand.

In the design of an apartment house, it is required to effectively utilize the floor area ratio and increase the number of dwelling units within a limited floor area ratio. In order to effectively use the floor area ratio, the design should incorporate a structure that is a space that can be used for daily life but is not included in the floor area, thereby obtaining the largest possible floor area within the limited floor area ratio. Can be.

[0004]

[Problems to be solved by the invention]

 This device is not included in the floor area when calculating the floor area ratio, but seeks to obtain an area that can be practically used for daily living by occupants, thereby achieving an atrium structure while effectively using the floor area ratio. It is.

[0005]

[Means for Solving the Problems]

 The open-well structure of the condominium according to the present invention is a maisonette-type condominium, in which a part of the ceiling of the lower floor is used as an atrium, and the atrium is closed at an appropriate height on the upper floor to form a loft. Things. According to a second aspect of the present invention, two rooms are provided on the upper floor with a stairwell interposed therebetween, and a partition wall is provided at an intermediate portion of the loft. The third aspect of the present invention opens the loft into an outer corridor. A door is provided. The invention according to claim 4 is that the ceiling height of the loft is a ceiling height that is not included in the floor area in the calculation of the floor area ratio.

[Embodiment of the invention]

 The figure shows a maisonette-type dwelling unit in an apartment house. Fig. 1 is a longitudinal section, Fig. 2 Floor plan of the lower floor (for example, the first floor), and Fig. 3 is floor plan of the upper floor (for example, the second floor). FIG. 4 is a floor plan of the loft portion.

An atrium 2 is formed at the entrance and the entrance hall of the lower floor 1, and an atrium 3 is formed at the living room. The atrium 3 of the living room is a continuous space to the ceiling of the upper floor 4. On the upper floor 4, two living rooms 5 and 6 are arranged with the stairwell 2 of the entrance hall portion interposed therebetween, and the stairwell 2 is located 1.4 meters below the ceiling surface of the upper floor 4. It is closed by a closing plate 7 that covers the upper portion of the blow-through portion 2 and a closing plate 8 that covers the side portion.

The upper part of the closing plate 7 covering the upper part constitutes a loft 9. The loft 9 is provided with a partition wall 10 extending to the ceiling at an intermediate portion, and the loft 9 is divided into two parts. Partition walls 11 and 12 are provided on both sides of the living rooms 5 and 6 to the ceiling. One partition wall 11 has an opening 13 to the living room 5, and the other partition wall 12 has an opening 13 to the living room 6. Parts 14 are provided respectively.

In this embodiment, since the partition wall 10 is provided in the middle of the loft 9, the two living rooms 5 and 6 can be used as independent storages. Since the ceiling height is 1.4 meters, it is not treated as a living room and is not counted in the floor area when calculating the floor area ratio. Although the loft 9 having the vertically long partition wall 10 is divided in the horizontal direction in FIG. 4, the loft 9 may be divided in the vertical direction.

The present invention can be implemented as the following structure in addition to the above embodiment. In the above embodiment, the loft 9 is divided by providing the partition wall 10, but the division is not essential. In the above embodiment, the partition walls 11 and 12 are provided on the living room side of the loft 9 to be used as a storage, but it is not essential to provide these partition walls. The loft 9 can be used as a bed. In the above embodiment, two rooms are provided with the loft 9 interposed therebetween, but the number of rooms adjacent to the loft may be one, or three or more. In the above-described embodiment, the partition walls 11 and 12 of the loft 9 are provided with openings 13 and 14 to the living room, respectively, so that the loft 9 can be used from each living room. It can also be used from. In the above embodiment, the loft is provided only in the atrium 2 in the entrance hall, but the loft can also be provided in the atrium 3 in the living room in a similar configuration.

[Effect of the invention]

According to this invention, in a maisonette type dwelling unit, the upper part of the atrium is closed to form a loft on the upper floor, so that the space available to the occupants is not reduced while the space is expanded by the atrium structure. However, the problem of area reduction due to the structure of the atrium is solved. Further, by making the ceiling height of the loft portion a height that is not included in the floor area in calculating the floor area ratio, it is possible to obtain a dwelling unit having a substantially large area within the range of the floor area ratio.
