In addition, in FIG. 3, the dwelling unit boundary line of each second-floor dwelling unit 16A, 16B is shown with the dashed-two dotted line.

  Each of the second-floor dwelling units 16A and 16B has a layout that is symmetrical with respect to the dwelling unit boundary line. Specifically, in each of the second-floor dwelling units 16A and 16B, in addition to the entrances 61A and 61B described above, LDKs 62A and 62B, Western rooms 63A and 63B, children's rooms 64A and 64B, bathrooms 65A and 65B, and toilets 66A 66B, washrooms 67A and 67B, storage rooms 68A and 68B, balconies 69A and 69B, and the like. In this case, the LDKs 62A and 62B, the Western rooms 63A and 63B, and the child rooms 64A and 64B correspond to the living room space, and the bathrooms 65A and 65B, the toilets 66A and 66B, the washrooms 67A and 67B, and the storage rooms 68A and 68B are the non-residential space. Equivalent to.

  The LDKs 62A and 62B and the Western rooms 63A and 63B are provided adjacent to the south outer wall portion 17c. Accordingly, each of the second-floor dwelling units 16A and 16B is provided with two rooms 62A and 63A (62B and 63B) facing south. Among these, LDK62A and 62B are adjacent to the east side outer wall part 17b besides the south side outer wall part 17c, and are suitable for both the south side and the east side. Further, the LDKs 62A and 62B are adjacent to the balconies 69A and 69B with the south outer wall 17c interposed therebetween, and windows 74A and 74B (for example, sweeping out) for entering and exiting the balconies 69A and 69B from the LDKs 62A and 62B to the south outer wall 17c. Window). The window portions 74A and 74B are provided with glass doors 75A and 75B for opening and closing the window portions 74A and 74B. In this case, the LDKs 62A and 62B are opened to the outdoors via the window portions 74A and 74B, and external light can be taken into the LDKs 62A and 62B through the window portions 74A and 74B.

  The Western rooms 63A and 63B are adjacent to each other with the second-floor wall 70 therebetween. The Western-style rooms 63A and 63B communicate with the outdoors through window portions 77A and 77B provided on the south-side outer wall portion 17c. In this case, external light can be taken into the Western rooms 63A and 63B through the window portions 77A and 77B.

That is, in the second-floor dwelling units 16A and 16B, these non-residential spaces 66A to 68A (66B to 68B) are arranged adjacent to the staircase 46, so that the living room spaces (LDK 62A, 62B, etc.) are separated from the staircase 46. It is arranged at a remote location, specifically at a location separated from the staircase 46 by another indoor space. The storage rooms 68A and 68B are disposed between the western rooms 63A and 63B and the staircase 46, and are separated from each other by the second-floor wall 70.

  In addition, the entrances 61A and 61B and the child rooms 64A and 64B are adjacent to the north side outer wall portion 17a, and the toilets 66A and 66B are adjacent to the lower part of the second floor corridor 22 with the partition walls 36 and 37 therebetween.

  As mentioned above, according to the structure of this embodiment explained in full detail, the following outstanding effects are acquired.

  The common passage portion 20 of the apartment 10 is provided between the adjacent dwelling units 15A and 15B (16A, 16B) in the first floor portion 11 and the second floor portion 12, respectively, and the adjacent first floor dwelling unit in the common passage portion 20 The first floor corridor lower part 21 leading to 15A, 15B and the second floor corridor lower part 22 leading to the adjacent second-floor dwelling units 16A, 16B are connected by a staircase portion 25 comprising a straight staircase. Then, in the plan view of the common passage portion 20, the first floor corridor lower portion 21 and the second floor corridor lower portion 22 are arranged on both sides of the lift passage portion 23 (step portion 25) in the ascending / descending direction of the staircase portion 25, and the first floor corridor The common entrance / exit 18 is disposed on the opposite side of the lifting / lowering passage portion 23 with the portion 21 interposed therebetween. In this case, since the first floor corridor lower part 21, the elevating passage part 23, and the second floor corridor lower part 22 are arranged in a straight line, the size of the passage width of the common passage part 20 is adjusted to the width of the stair part 25 composed of a straight staircase. As a result, the passage width of the shared passage portion 20 can be made smaller than the width of the staircase in which the folded staircase is installed. Thereby, since the ratio which the shared passage part 20 occupies with respect to the entrance of the apartment house 10 can be made small in the house front side in which the common entrance 18 is provided in the apartment house 10, the shared passage part on the house front side A wide space in the dwelling unit can be secured on both sides of the 20. As a result, it is possible to obtain the dwelling units 15 and 16 that are easy to ensure daylighting. Further, in the above-described configuration in which the space in the dwelling unit is widely secured on the front side of the house by reducing the passage width of the common passage part 20, the entrance of the apartment house 10 is suppressed from increasing, that is, the apartment house. It becomes possible to obtain the dwelling units 15 and 16 in which it is easy to ensure the daylighting performance while suppressing the reduction of the ten site capacity.

  In particular, in the apartment house 10 in which the common entrance 18 is provided on the south side of the apartment house 10, the front side of the house faces the south side with good lighting conditions. Can be obtained while suppressing the decline in site response.

  Moreover, since the width of the common entrance 18 for entering / exiting the common passage part 20 can be reduced by reducing the passage width of the common passage part 20, the front side of the apartment house 10 is made to have a clean appearance. You can also.

  In the first-floor portion 11, the first-floor dwelling units 15 </ b> A and 15 </ b> B that are adjacent to each other with the first-floor lower portion 21 interposed therebetween are partitioned by a first-floor boundary wall 60 provided below the second-floor lower portion 22. The second-floor dwelling units 16A and 16B adjacent to each other with the part 22 interposed therebetween are partitioned by a second-floor boundary wall 70 provided above the lower part of the first-floor corridor 21. In this case, the common passage portion 20 is provided between the adjacent dwelling units 15 and 16, and the upper space of the first floor corridor lower portion 21 and the lower space of the second floor corridor lower portion 22 are respectively connected to the dwelling units 15 and 16. It can be used as a dwelling unit space, and a wide dwelling unit space can be secured.

  Since the first-level boundary wall 60 and the second-level boundary wall 70 are arranged in a line along the central portion of the common passage portion 20 in a plan view, the floor plan of each adjacent dwelling unit 15A, 15B (16A, 16B) is It becomes possible to make it symmetrical with respect to the wall 60 (70). Thereby, it is possible to obtain advantages such as common use of building members and reduction of design load.

  Since the window portion 40 that allows the second floor corridor lower portion 22 to communicate with the outside is provided on the north side outer wall portion 17 a, external light can be introduced into the second floor corridor lower portion 22 through the window portion 40. As a result, the second floor corridor lower portion 22 that is difficult to reach outside light taken in through the entrance / exit 18 is darkened because it is provided on the opposite side of the common entrance / exit 18 in the linear common passage portion 20. Can be suppressed.

  The window part 40 was formed in the north side outer wall part 17a located in the end of the shared channel | path part 20, and was opposingly arranged on both sides of the shared entrance / exit 18 and the shared channel | path part 20 in planar view. As a result, when moving to the entrances 51A, 51B, 61A, 61B of the respective dwelling units 15A, 15B, 16A, 16B through the common passage section 20, while looking at the window section 40 in the front, the outdoor section through the window section 40 You can move while watching. Thereby, it can suppress feeling a blockage in moving the common passage part 20 used as a dead end in the north side outer wall part 17a.

  In the dwelling units 15A, 15B, 16A, and 16B, the indoor spaces adjacent to the elevating passage section 23 (the staircase 46) are used as water surrounding spaces such as washrooms 57A and 57B and bathrooms 55A and 55B. The living room space such as 53B can be arranged at a position away from the lift passage 23. Thereby, since it can suppress that the noise and vibration which arise with the up-and-down of the staircase part 25 are transmitted to living room space, giving a discomfort to a resident by this noise and vibration can be suppressed.

  In each first-floor dwelling unit 15A, 15B, the entrances 51A, 51B and the child rooms 54A, 54B are arranged adjacent to the first-floor lower part 21 with partition walls 26, 27, respectively, and the entrances 51A, 51B are placed in the child rooms 54A, It arrange | positioned near the staircase part 25 (elevating passage part 23) rather than 54B. In this case, the child rooms 54A and 54B as living rooms are arranged adjacent to the lower floor 21 of the first floor, and the child rooms 54A and 54B can be arranged on the front side of the apartment house 10. . For this reason, it can be said that it is a preferable configuration for securing a large room space on the front side of the house.

  In the apartment house 10, two south facing rooms are provided in each of the adjacent dwelling units 15 </ b> A, 15 </ b> B, 16 </ b> A, 16 </ b> B across the common passage 20. Specifically, the first floor dwelling units 15A and 15B are provided with LDKs 52A and 52B and child rooms 54A and 54B, and the second floor dwelling units 16A and 16B are provided with LDKs 62A and 62B and Western rooms 63A and 63B. Therefore, the dwelling units 15 and 16 preferable in terms of daylighting can be obtained. In addition, even in the configuration in which two rooms facing south are provided in this way, it is possible to suppress the frontage of the apartment 10 from becoming large. Excellent dwelling units 15 and 16 can be obtained.

  In each first-floor dwelling unit 15A, 15B, the indoor space adjacent to the first-floor boundary wall 60 is only the bathrooms 35A, 35B, in other words, only the non-room space. In this case, in each first-floor dwelling unit 15A, 15B, the living room spaces (for example, Western rooms 53A, 53B, etc.) are not adjacent to each other with the boundary wall 60 therebetween, so in the living room space, the adjacent dwelling unit 15A (or 15B) The noise is difficult to be transmitted. Therefore, it can be said that this is a preferable configuration in terms of noise countermeasures between the dwelling units 15A and 15B.

  A part of the first floor corridor 21 is projected to the entrance 51A, 51B side of the first floor dwelling unit 15A, 15B to form the entrance space 34, 35, and the entrance door 29A is formed in the entrance space 34, 35. 29B is opened and closed. As a result, the passage width of the first floor corridor lower portion 21 is sized to match the width of the staircase portion 25 composed of a straight staircase, and the passage in the lower first floor corridor 21 is prevented by opening and closing the entrance doors 29A and 29B. It can be prevented from being hindered. In particular, in the configuration in which the entrances 28A and 28B of the first-floor dwelling units 15A and 15B are opposed to each other with the first-floor corridor lower part 21 in between, if both the entrance doors 29A and 29B are opened and closed simultaneously, the doors 29A and 29B Since there is a possibility of interference, there is an advantage that it can be avoided.

  Similarly, a part of the second floor corridor lower part 22 is also extended to the entrance 61A, 61B side of the second floor dwelling units 16A, 16B to form front entrance spaces 44, 45. Since the entrance doors 39A and 39B are opened and closed, the same effect as the front entrance spaces 34 and 35 in the lower part of the first floor corridor 21 can be obtained.

  The present invention is not limited to the above embodiment, and may be implemented as follows, for example.

  (1) In the above embodiment, the end of the shared passage portion 20 is the north outer wall portion 17a, but the end of the shared passage portion 20 may be set before the north side outer wall portion 17a. That is, as shown in FIG. 4, the end of the common passage portion 20 may be set closer to the common entrance / exit than the north side outer wall portion 17 a, and the second floor corridor lower portion 82 may be spaced apart from the north side outer wall portion 17 a. In this case, in the second-floor portion 12, a second-floor boundary wall 85 that partitions the second-floor dwelling units 83 </ b> A and 83 </ b> B can be disposed between the second-floor lower portion 82 and the north-side outer wall portion 17 a. According to such a configuration, almost the entire area in the frontage direction on the north surface (in other words, the back surface) of the apartment house 10 can be used as the wall surface of the second-floor dwelling units 83A and 83B, and thus opens to the second-floor dwelling units 83A and 83B, for example, northward. It is possible to form a large opening window.

  (2) In the above embodiment, the length of the second floor corridor lower portion 22 (the length in the passage extending direction) is shorter than the length of the first floor corridor lower portion 21 in the shared passage portion 20, but this is changed to The length of the lower corridor 21 may be shorter than the length of the second corridor lower 22. In this case, the staircase portion 25 is disposed closer to the shared entrance 18 than the central portion in the passage extending direction in the common passage portion 20, and is disposed in front of the central portion in the depth direction in the apartment house 10. It becomes. Therefore, it can be considered that the entrances 51A and 51B of the first-floor dwelling units 15A and 15B leading to the first-floor corridor 21 are arranged on the front side of the apartment house 10, for example. Note that the length of the first floor corridor lower portion 21 and the length of the second floor corridor lower portion 22 may be the same length.

  (3) In the above embodiment, the first-floor wall 60 and the second-floor wall 70 are arranged in a line along the central portion in the passage width direction of the common passage portion 20 in plan view. The arrangement mode is not necessarily limited to this. For example, the first floor wall 60 and the second floor wall 70 may be arranged so as to be shifted in a direction orthogonal to the passage extending direction in plan view. Further, the first floor wall 60 may be disposed at a location different from the lower position of the second floor corridor 22, or the second floor wall 70 may be disposed at a location different from the upper position of the first floor corridor 21. .

  (4) The first floor corridor lower portion 21 may be an atrium space that extends vertically across the first floor portion 11 and the second floor portion 12. In this case, if the second floor part 12 of the south side outer wall part 17c is provided with a window part that opens the lower part of the first floor corridor (the atrium space) to the outside, the outside light can be sufficiently taken into the lower part of the first floor corridor through the window part, It becomes possible to make the shared passage part 20 brighter.
