Description

[Technical Field]

[0001] The present disclosure relates to buildings. [Background technology]

[0002] A delivery system that uses drones to deliver packages is known (for example, see Patent Document 1). In Patent Document 1, drones deliver packages to each dwelling unit in a building. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 2018-112029 Summary of the Invention [Problem to be solved by the invention]

[0004] In order for a building to receive deliveries by drone, it needs a large space that allows drones carrying packages to easily enter the building. While it would be ideal to use the building's garden as a drone port, it can be difficult to secure a large space on each floor of a multi-story building that allows drones to easily enter. [Means for solving the problem]

[0005] (1) A building that solves the above problem is a building with multiple floors, comprising a building body and a protrusion portion provided on each floor of the building body so as to protrude from the outer wall of the building body in a protrusion direction toward the outside of the building body, and the protrusion portion is shifted laterally relative to the protrusion portion of the floor immediately above so that at least a portion of the protrusion portion does not overlap the protrusion portion of the floor immediately above the protrusion portion in a plan view.

[0006] With this configuration, at least a portion of the overhang is laterally offset relative to the overhang on the floor directly above in a plan view, creating a two-story atrium above at least a portion of the overhang. This atrium can be used as an entry route for drones, making it easier for drones to deliver goods to the overhang.

[0007] (2) In the building described in (1) above, the building is an apartment building, each floor has a dwelling unit, the width of the protrusion in the horizontal direction is shorter than the width of the dwelling unit in the horizontal direction, and at least a portion of the protrusion of the floor directly below the protrusion is located below the part of the dwelling unit where the protrusion in the horizontal direction is not provided.

[0008] With this configuration, at least a portion of the overhang on the floor directly below is located below the portion of the dwelling unit that does not have a horizontal overhang, creating a two-story atrium above at least a portion of the overhang on the floor directly below. By using this atrium as an entry route for drones, it becomes easier to receive deliveries by drone at the overhang on the floor directly below.

[0009] (3) In the building described in (1) or (2) above, the protrusions on odd-numbered floors are shifted laterally in the same direction and by the same amount relative to the protrusions on even-numbered floors.

[0010] With this configuration, an atrium can be formed above at least a portion of each protruding portion other than the top floor.

[0011] (4) In a building described in any one of (1) to (3) above, a shielding portion is provided on the exterior wall so as to extend from the exterior wall in the extension direction, and in a plan view, the shielding portion is located between the extension portion and the extension portion of the floor immediately above the extension portion, and the shielding portion extends in the vertical direction from the extension portion to the extension portion of the floor immediately above.

[0012] With this configuration, the shielding portion is located between the overhanging portion and the overhanging portion of the floor directly above in a plan view, and the shielding portion extends from the overhanging portion to the overhanging portion of the floor directly above. This makes it difficult to look down on the overhanging portion of the floor directly below from the overhanging portion. This prevents each overhanging portion from being seen from the overhanging portion of the floor directly above, ensuring privacy.

[0013] (5) In the building described in (4) above, the length of the shielding portion in the projection direction is greater than the length of the projection portion in the projection direction.

[0014] With this configuration, the length of the shielding portion in the projection direction is greater than the length of the protruding portion in the projection direction, so the shielding portion projects out further in the projection direction than the protruding portion. Because the shielding portion blocks wind blowing in the lateral direction, the building can reduce the effect of wind on drones entering the protruding portion.

[0015] (6) In the building described in any one of (1) to (5) above, a roof protrusion is provided on the roof so as to protrude from the roof of the building body in the protrusion direction, and the roof protrusion overlaps at least a portion of the protrusion in a plan view.

[0016] According to this configuration, the roof overhang is located above at least a portion of the overhang in a plan view, so that the effects of weather on at least a portion of the overhang can be suppressed.

[0017] (7) In the building described in (6) above, the roof overhang overlaps the overhang of the top floor in a plan view, and an upper opening that opens in the vertical direction is formed in the portion of the roof overhang that overlaps the overhang of the top floor in a plan view.

[0018] With this configuration, an upper opening is formed in the roof overhang, allowing a drone to enter the overhang on the top floor using the upper opening as an entry route.

[0019] (8) In the building described in (7) above, the upper opening is provided with a rooftop shielding section that opens and closes the upper opening.

[0020] With this configuration, the upper opening can be closed by the rooftop shielding portion.

[0021] (9) In the building described in any one of (1) to (8) above, the area of ​​the protruding part is 7 m 2 In the above, the length of the protruding portion in the protruding direction is 2 m or more.

[0022] According to this configuration, the area is 7m 2 Furthermore, compared to a protrusion whose length in the protrusion direction is less than 2 m, the protrusion protrudes significantly in the protrusion direction, making it easier for drones to enter the protrusion.

[0023] (10) In a building described in any one of (1) to (9) above, a drone port is provided in a portion of the protrusion that does not overlap with the protrusion of the floor immediately above the protrusion in a plan view.

[0024] The drone port allows the drone to recognize the location on the overhanging section that it is permitted to enter. With the above configuration, it is easy for the drone to enter the portion of the overhanging section that does not overlap with the overhanging section of the floor immediately above in a plan view. [Effects of the Invention]

[0025] According to the building disclosed herein, deliveries can be made by drone on each floor of the building. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0027] <Embodiment> A building 10 according to an embodiment will be described with reference to FIGS. 1 to 6. FIG.

[0028] <Buildings> As shown in Figures 1 and 2, building 10 has multiple floors. Building 10 is an apartment building. Each floor of building 10 has a dwelling unit 11. In the example of Figure 1, building 10 is four stories tall, with two dwelling units 11 on each floor. Building 10 may also have two, three, or five or more floors. Building 10 may also be a detached house with two or more floors.

[0029] In this embodiment, the building 10 comprises a first dwelling unit 11a located on the second floor, a second dwelling unit 11b located on the third floor directly above the first dwelling unit 11a, a third dwelling unit 11c located on the second floor next to the first dwelling unit 11a, and a fourth dwelling unit 11d located on the third floor directly above the third dwelling unit 11c.

[0030] The building 10 comprises a building main body 12 and an overhang 13. Each dwelling unit 11 comprises an entrance hall, a living room, and the overhang 13. The entrance hall and the living room are provided in the building main body 12. The overhang 13 is provided on an outer wall 14 of the building main body 12. The building main body 12 may be provided with a staircase or elevator for shared use by residents.

[0031] <Overhang> 1 and 2, the protruding portion 13 is provided on each floor of the building main body 12 so as to protrude in a protruding direction X1. The protruding direction X1 is a direction from the outer wall 14 of the building main body 12 toward the outside of the building main body 12.

[0032] The overhang 13 is connected to the interior of the dwelling unit 11. The residents of the dwelling unit 11 can enter and exit the overhang 13 from the dwelling unit 11 through an opening 15. The opening 15 is, for example, a French window. The overhang 13 is configured as, for example, a balcony, veranda, terrace, or deck. The overhang 13 on the first floor may be configured as a terrace or a deck.

[0033] A handrail 16 is provided on the overhanging portion 13. The handrail 16 is provided at the end of the overhanging portion 13 in the overhanging direction X1. The handrail 16 is formed by a wall so that the inside of the overhanging portion 13 cannot be seen from outside the building main body 12. The handrail 16 may be formed by a panel or a lattice.

[0034] 2, the overhanging portion 13 is offset in the lateral direction X2 relative to the overhanging portion 13 of the floor immediately above so that at least a portion of the overhanging portion 13 does not overlap with the overhanging portion 13 of the floor immediately above in a plan view. In this embodiment, the overhanging portion 13 is offset in the lateral direction X2 relative to the overhanging portion 13 of the floor immediately above so that the entire overhanging portion 13 does not overlap with the overhanging portion 13 of the floor immediately above in a plan view. For example, the overhanging portion 13 of the first dwelling unit 11a does not overlap with the overhanging portion 13 of the second dwelling unit 11b in a plan view.

[0035] As shown in Figures 3 and 4, a portion of an exterior wall 14 corresponding to one dwelling unit 11 (hereinafter referred to as the exterior wall portion) is divided into a portion where a protrusion 13 is provided and a portion where no protrusion 13 is provided in a plan view. The protrusions 13 of adjacent dwelling units 11 are not connected in the horizontal direction X2. The protrusions 13 of two adjacent dwelling units 11 are separated from each other. A bay window 15a may be provided in the portion of the exterior wall of a dwelling unit 11 where no protrusion 13 is provided. As shown in Figure 2, in a first-floor dwelling unit 11, an opening 15 communicating with the garden may be provided in place of a bay window 15a in the portion of the exterior wall where no protrusion 13 is provided.

[0036] As shown in Figure 3, the width W1 of the overhanging portion 13 in the horizontal direction X2 is shorter than the width W2 of the dwelling unit 11 in the horizontal direction X2. For example, the width W1 of the overhanging portion 13 is equal to or less than half the width W2 of the dwelling unit 11. The widths W1 of the overhanging portions 13 are equal to each other. The widths W2 of the dwelling units 11 are equal to each other.

[0037] At least a part of the protrusion 13 provided on the floor directly below is located below the portion of the dwelling unit 11 where the protrusion 13 is not provided in the horizontal direction X2. In this embodiment, the entire protrusion 13 provided on the floor directly below is located below the portion of the exterior wall portion corresponding to the dwelling unit 11 where the protrusion 13 is not provided in the horizontal direction X2. For example, the protrusion 13 of the first dwelling unit 11a is located below the portion of the exterior wall portion corresponding to the second dwelling unit 11b where the protrusion 13 is not provided in the horizontal direction X2.

[0038] As shown in FIG. 6, an atrium 25 is formed above the portion of the overhang 13 that does not overlap with the overhang 13 of the floor directly above. When viewed from the front of the building 10, the atrium 25 overlaps the portion of the exterior wall of the dwelling unit 11 where the overhang 13 is not provided. The atrium 25 forms an entry route for drones 30 accessing the overhang 13. A drone port 24 is provided in the portion of the overhang that does not overlap with the overhang 13 of the floor directly above, as described below. The atrium 25 is located above the drone port 24. The height H1 of the atrium 25 is 4 m or more. The height H1 of the atrium 25 is defined as the height from the top end of the handrail 16 of the overhang 13 to the overhang 13 directly above.

[0039] As shown in Figures 2 to 4, in this embodiment, the protrusions 13 on odd-numbered floors are shifted in the horizontal direction X2 in the same direction and by the same shift width relative to the protrusions 13 on even-numbered floors. The protrusions 13 on odd-numbered floors that are aligned in the vertical direction X3 overlap with the protrusions 13 on other odd-numbered floors in a plan view. The protrusions 13 on odd-numbered floors have the same shape as one another in a plan view. The protrusions 13 on even-numbered floors that are aligned in the vertical direction X3 overlap with the protrusions 13 on other even-numbered floors in a plan view. The protrusions 13 on even-numbered floors have the same shape as one another in a plan view.

[0040] For example, the direction in which the overhang portion 13 of the first dwelling unit 11a is shifted relative to the overhang portion 13 of the second dwelling unit 11b is the same as the direction in which the overhang portion 13 of the third dwelling unit 11c is shifted relative to the overhang portion 13 of the fourth dwelling unit 11d. Also, the amount of shift of the overhang portion 13 of the first dwelling unit 11a relative to the overhang portion 13 of the second dwelling unit 11b is the same as the amount of shift of the overhang portion 13 of the third dwelling unit 11c relative to the overhang portion 13 of the fourth dwelling unit 11d.

[0041] As shown in FIG. 3, the area of ​​the protruding portion 13 is 7 m 2 As described above, the length L1 of the protruding portion 13 in the protruding direction X1 is 2 m or more. The width W1 of the protruding portion 13 in the lateral direction X2 is, for example, 3.5 m or more. The shape of the protruding portion 13 is, for example, rectangular. The shape of the protruding portion 13 does not have to be rectangular as long as it is wide enough to provide a drone port 24, which will be described later.

[0042] <Shielding part> 1 and 2, the building 10 includes a shielding portion 17. The shielding portion 17 is provided on the outer wall 14 of the building main body 12 so as to protrude in the protruding direction X1. The shielding portion 17 is configured as, for example, a sleeve wall.

[0043] The shielding portion 17 has a first shielding portion 18 and a second shielding portion 19. The first shielding portion 18 is located at the center of the dwelling unit 11 in the horizontal direction X2 in the exterior wall portion corresponding to the dwelling unit 11. The second shielding portion 19 is located at the end of the dwelling unit 11 in the horizontal direction X2 in the exterior wall portion corresponding to the dwelling unit 11. In the horizontal direction X2, one dwelling unit 11 is located between two second shielding portions 19. In the horizontal direction X2, one protrusion portion 13 is located between the first shielding portion 18 and the second shielding portion 19.

[0044] In a plan view, a shielding portion 17 is located between the overhanging portion 13 and the overhanging portion 13 of the floor immediately above the overhanging portion 13. For example, a first shielding portion 18 is located between the overhanging portion 13 of the first dwelling unit 11a and the overhanging portion 13 of the second dwelling unit 11b in the horizontal direction X2. In a plan view, a shielding portion 17 is also located between the overhanging portion 13 and the adjacent overhanging portion 13 of the floor immediately above. For example, a second shielding portion 19 is located between the overhanging portion 13 of the first dwelling unit 11a and the overhanging portion 13 of the fourth dwelling unit 11d in the horizontal direction X2.

[0045] The shielding portions 17 extend in the vertical direction X3 from the overhanging portion 13 to the overhanging portion 13 of the floor immediately above. In this embodiment, the shielding portions 17 provided corresponding to the dwelling units 11 on each floor are connected to each other. The connected shielding portions 17 are continuous from the ground to the roof 20 of the building main body 12 in the vertical direction X3.

[0046] 3, the length L2 of the shielding portion 17 in the extension direction X1 is greater than the length L1 of the extension portion 13 in the extension direction X1. The length L2 of the shielding portion 17 is, for example, 2.5 m or more. The length L2 of the shielding portion 17 is preferably 3 m or more.

[0047] 3 and 4, the arrangement of the overhanging portion 13 in the dwelling unit 11 is symmetrical in the horizontal direction X2 with respect to the arrangement of the overhanging portion 13 of the dwelling unit 11 directly above or directly below it in a plan view with respect to the first shielding portion 18. Here, the arrangement of the overhanging portion 13 refers to the shape of the overhanging portion 13 and the position of the overhanging portion 13 relative to the exterior wall portion of the dwelling unit 11. For example, the arrangement of the overhanging portion 13 of the first dwelling unit 11a is symmetrical in the horizontal direction X2 with respect to the arrangement of the overhanging portion 13 of the second dwelling unit 11b with respect to the first shielding portion 18.

[0048] The arrangement of the overhanging portions 13 in the dwelling unit 11 is the same as the arrangement of the overhanging portions 13 in the adjacent dwelling unit 11. For example, the arrangement of the overhanging portions 13 in the first dwelling unit 11a is the same as the arrangement of the overhanging portions 13 in the third dwelling unit 11c.

[0049] <Roof overhang> As shown in Figures 1 and 2, the building 10 has a roof overhang 21. The roof overhang 21 is provided on the roof 20 of the building main body 12 so as to overhang in the overhang direction X1 from the roof 20. The upper surface of the roof overhang 21 is continuous with the roof of the building main body 12. The roof overhang 21 is provided between the two shielding portions 17 in the lateral direction X2. The roof overhang 21 overlaps at least a portion of the overhang 13 in a plan view.

[0050] The roof overhang 21 overlaps with the overhang 13 of the top floor in plan view. In this embodiment, the top floor is the fourth floor. At least a portion of the roof overhang 21 is located directly above the overhang 13 of the fourth floor in plan view.

[0051] An upper opening 22 that opens in the vertical direction X3 is formed in a portion of the roof overhang 21 that overlaps with the overhang 13 of the top floor in a plan view. The upper opening 22 is located, for example, directly above the overhang 13 of the top floor. The upper opening 22 overlaps with the drone port 24 in a plan view.

[0052] 5, the length L3 of the upper opening 22 in the projection direction X1 is, for example, 2 m or more. The width W3 of the upper opening 22 in the lateral direction X2 is, for example, 2 m or more. The width W3 of the upper opening 22 in the lateral direction X2 is preferably 3.5 m or more.

[0053] The upper opening 22 is provided with a rooftop shielding part 23 that opens and closes the upper opening 22. In the example of Fig. 5, the upper opening 22 on the left side is open. The upper opening 22 on the right side is closed by the rooftop shielding part 23.

[0054] The rooftop shielding unit 23 is configured as, for example, an awning. In one example, the awning is configured as a foldable sheet. A shutter may be used as the rooftop shielding unit 23. The rooftop shielding unit 23 is configured to be electrically opened and closed. The rooftop shielding unit 23 is opened and closed by, for example, an electric arm 23a.

[0055] As shown in FIG. 2, in this embodiment, roof overhang 21 further overlaps overhang 13 provided on the floor immediately below the top floor in a plan view. The floor immediately below the top floor is the third floor. Roof overhang 21 is located directly above overhang 13 on the top floor, and is also located directly above overhang 13 on the floor immediately below the top floor. Height H2 from the top end of handrail 16 of overhang 13 immediately below the top floor to the bottom end of roof overhang 21 directly above is, for example, 4 m or more.

[0056] <Drone Port> As shown in Fig. 6, a drone port 24 is provided on the overhang 13 of the building 10. The drone port 24 is configured as a location where a delivery drone 30 can take off and land. In this embodiment, the drone 30 is an unmanned flying object that can be remotely or automatically controlled.

[0057] As shown in Figures 3 to 5, drone ports 24 are provided in portions of the overhanging portion 13 that do not overlap with the overhanging portion 13 of the floor immediately above in plan view. In other words, drone ports 24 are provided in the portions of the overhanging portion 13 where the atrium 25 is located. Drone ports 24 are also provided in portions of the overhanging portion 13 of the top floor that overlap with the upper opening 22 of the roof overhang 21 in plan view. In Figures 3 and 4, the areas of the overhanging portion 13 where drone ports 24 are provided are indicated by dotted hatching. Drones 30 may land in areas other than those indicated by dotted hatching.

[0058] The area where the drone port 24 is provided is, for example, rectangular. The area of ​​the drone port 24 is 4 m 2 That's all. The length L4 of the drone port 24 in the extension direction X1 is 2 m or more. The width W4 of the drone port 24 in the lateral direction X2 is 2 m or more. The area where the drone port 24 is provided may have a shape other than rectangular. A clothesline, an air conditioner outdoor unit, a drainage ditch, etc. may be provided in the area of ​​the extension portion 13 where the drone port 24 is not provided.

[0059] Each dwelling unit 11 may be provided with guidance equipment for guiding the drone 30 to the drone port 24. For example, when the guidance equipment detects the approach of the drone 30, it transmits information regarding the location of the drone port 24 to the drone 30. The information regarding the location of the drone port 24 is information for guiding the drone 30, such as the GPS coordinates of the building 10, information identifying the building 10, and information regarding the floor of the drone port 24. Such guidance equipment may be provided in the drone port 24 to communicate directly with the drone 30, or may be provided within the dwelling unit 11 to communicate with the drone 30 via a network such as the Internet.

[0060] In the top floor dwelling unit 11, when the guidance equipment detects the approach of the drone 30, the guidance equipment operates the rooftop shielding unit 23 to open the upper opening 22. When the drone 30 finishes delivering the package and leaves the dwelling unit 11 through the upper opening 22, the guidance equipment operates the rooftop shielding unit 23 to close the upper opening 22.

[0061] The drone ports 24 may be provided with marks that can be read by a camera built into the drone 30. The drone 30 can identify the target drone port 24 by reading the marks on the drone ports 24.

[0062] <Operation of this embodiment> The first function of this embodiment will be described. In the building 10, at least a portion of the overhanging portion 13 is shifted in the lateral direction X2 relative to the overhanging portion 13 of the floor immediately above so as not to overlap with the overhanging portion 13 of the floor immediately above in a plan view, and therefore an atrium 25 is formed above at least a portion of the overhanging portion 13. The drone 30 can enter the overhanging portion 13 using this atrium 25 as an entry route.

[0063] A second function of this embodiment will be described. In the building 10, the dwelling units 11 lined up in the vertical direction X3 are arranged so that the overhanging portions 13 on the odd-numbered floors and the overhanging portions 13 on the even-numbered floors are offset in the horizontal direction X2. By alternately arranging the overhanging portions 13 in the dwelling units 11 lined up in the vertical direction X3, the design of the facade surface of the building 10 is improved.

[0064] <Effects of this embodiment> The effects of this embodiment will be described. (1) The protrusion 13 is provided on each floor of the building body 12 so as to protrude from the outer wall 14 of the building body 12 in a protrusion direction X1 toward the outside of the building body 12. The protrusion 13 is shifted in the lateral direction X2 relative to the protrusion 13 on the floor immediately above so that at least a portion of the protrusion 13 does not overlap the protrusion 13 on the floor immediately above in a plan view.

[0065] According to this configuration, at least a portion of the overhanging portion 13 is shifted in the lateral direction X2 relative to the overhanging portion 13 of the floor immediately above in a plan view, so that a two-story void 25 is formed above at least a portion of the overhanging portion 13. This void 25 can be used as an entry route for drones 30, making it easier for the overhanging portion 13 to receive deliveries by drones 30.

[0066] (2) Building 10 is an apartment building. Each floor has a dwelling unit 11. The width W1 of protrusion 13 in the horizontal direction X2 is shorter than the width W2 of dwelling unit 11 in the horizontal direction X2. At least a portion of protrusion 13 of the floor directly below is located below the portion of dwelling unit 11 where protrusion 13 is not provided in the horizontal direction X2.

[0067] According to this configuration, at least a part of the overhang 13 of the floor directly below is located below the part of the dwelling unit 11 in the horizontal direction X2 where no overhang 13 is provided, so that a two-story void 25 is formed above the overhang 13 of the floor directly below. By using this void 25 as an entry route for the drone 30, it becomes easier to receive deliveries by the drone 30 at the overhang 13 of the floor directly below.

[0068] (3) The protruding portions 13 on odd-numbered floors are shifted in the horizontal direction X2 in the same direction and by the same shift width relative to the protruding portions 13 on even-numbered floors.

[0069] According to this configuration, an atrium 25 can be formed above at least a portion of each of the protruding portions 13 on the floors other than the top floor.

[0070] (4) The building 10 includes a shielding portion 17. The shielding portion 17 is provided on the exterior wall 14 so as to extend from the exterior wall 14 in the extension direction X1. In a plan view, the shielding portion 17 is located between the extension portion 13 and the extension portion 13 of the floor immediately above the extension portion 13. The shielding portion 17 extends in the vertical direction X3 from the extension portion 13 to the extension portion 13 of the floor immediately above.

[0071] According to this configuration, in a plan view, the shielding portion 17 is located between the overhanging portion 13 and the overhanging portion 13 of the floor immediately above, and the shielding portion 17 extends from the overhanging portion 13 to the overhanging portion 13 of the floor immediately above. This makes it difficult to look down on the overhanging portion 13 of the floor immediately below from the overhanging portion 13. This prevents each overhanging portion 13 from being seen from the overhanging portion 13 of the floor immediately above, ensuring privacy for each overhanging portion 13.

[0072] (5) The length L2 of the shielding portion 17 in the extension direction X1 is greater than the length L1 of the extension portion 13 in the extension direction X1.

[0073] According to this configuration, the length L2 of the shielding portion 17 is greater than the length L1 of the overhanging portion 13, and therefore the shielding portion 17 extends further in the overhanging direction X1 than the overhanging portion 13. Because the shielding portion 17 blocks wind blowing in the lateral direction X2, the building 10 can suppress the effect of wind on the drone 30 entering the overhanging portion 13.

[0074] (6) The building 10 includes a roof protrusion 21. The roof protrusion 21 is provided on the roof 20 so as to protrude from the roof 20 in a protrusion direction X1. The roof protrusion 21 overlaps at least a portion of the protrusion 13 in a plan view.

[0075] According to this configuration, the roof overhang 21 is located above at least a portion of the overhang 13, so that the effect of weather on at least a portion of the overhang 13 can be suppressed.

[0076] (7) The roof projection 21 overlaps the projection 13 of the top floor in a plan view. An upper opening 22 that opens in the vertical direction X3 is formed in the portion of the roof projection 21 that overlaps the projection 13 of the top floor in a plan view.

[0077] According to this configuration, an upper opening 22 is formed in the roof overhang 21, so that the drone 30 can enter the overhang 13 on the top floor using the upper opening 22 as an entry route.

[0078] (8) The upper opening 22 is provided with a rooftop shielding section 23 that opens and closes the upper opening 22.

[0079] According to this configuration, the rooftop shielding portion 23 can close the upper opening 22.

[0080] (9) The area of ​​the projection 13 is 7 m 2 As described above, the length L1 of the extension portion 13 in the extension direction X1 is 2 m or more.

[0081] According to this configuration, the area is 7m 2 Furthermore, compared to a protrusion having a length of less than 2 m in the protrusion direction X1, the protrusion portion 13 protrudes more in the protrusion direction X1, so it is easier for the drone 30 to enter the protrusion portion 13.

[0082] (10) A drone port 24 is provided in a portion of the projection 13 that does not overlap with the projection 13 of the floor directly above the projection 13 in a plan view.

[0083] The drone port 24 allows the drone 30 to recognize the location on the overhang 13 where it is permitted to enter. According to the above configuration, it is easy for the drone 30 to enter a portion of the overhang 13 that does not overlap with the overhang 13 on the floor immediately above in a plan view.

[0084] <Modification> The above-described embodiment is an example of a form that the building 10 can take, and is not intended to limit the form. The building 10 can take a form different from the form exemplified in the above-described embodiment. Examples of such a form include a form in which part of the configuration of the embodiment is replaced, modified, or omitted, or a form in which a new configuration is added to the embodiment. Modified examples of the embodiment are shown below.

[0085] In the example shown in Figure 7, the configuration of the row of dwelling units 11, including the third dwelling unit 11c, in the vertical direction X3 differs from the configuration of the embodiment. As in the example shown in Figure 7, the arrangement of the overhanging portions 13 in the dwelling units 11 may be symmetrical in the horizontal direction X2 with respect to the arrangement of the overhanging portions 13 of the adjacent dwelling units 11. For example, the arrangement of the overhanging portions 13 of the first dwelling unit 11a is symmetrical in the horizontal direction X2 with respect to the arrangement of the overhanging portions 13 of the third dwelling unit 11c with respect to the second shielding portion 19 located between the first dwelling unit 11a and the third dwelling unit 11c. Furthermore, the arrangement of the overhanging portions 13 of the second dwelling unit 11b is symmetrical in the horizontal direction X2 with respect to the arrangement of the overhanging portions 13 of the fourth dwelling unit 11d with respect to the second shielding portion 19 located between the second dwelling unit 11b and the fourth dwelling unit 11d. In this modification, the protrusions 13 of adjacent dwelling units 11 on odd-numbered floors are continuous in the horizontal direction X2. The protrusions 13 of adjacent dwelling units 11 on even-numbered floors are not continuous in the horizontal direction X2 and are separated from each other.

[0086] In the example shown in FIG. 8, the configuration of the overhanging portion 13 differs from that of the embodiment. As in the example shown in FIG. 8, in a plan view, a portion of the overhanging portion 13 may overlap a portion of the overhanging portion 13 on the floor immediately above or below. The portion that overlaps with the portion of the overhanging portion 13 on the floor immediately above or below is preferably a portion of the overhanging portion 13 other than the area where the drone port 24 is provided. This allows the overhanging portion 13 to be widened while maintaining the size of the drone port 24. In this modification, the first shielding portion 18 does not have to be continuous in the vertical direction X3.

[0087] In the building 10 according to the embodiment, drone ports 24 are provided in all of the overhanging portions 13, but drone ports 24 may be provided only in specific overhanging portions 13. As an example, drone ports 24 may be provided only in overhanging portions 13 on odd-numbered floors. When drone ports 24 are provided only in overhanging portions 13 on odd-numbered floors, drone ports 24 are not provided in overhanging portions 13 on even-numbered floors, and therefore the width of the overhanging portions 13 on odd-numbered floors in the horizontal direction X2 may be the same as the width W2 of the dwelling unit 11 in the horizontal direction X2. The specific overhanging portions 13 may be not only the overhanging portions 13 on odd-numbered floors, but also the overhanging portions 13 on even-numbered floors, or may be the overhanging portions 13 on a specific floor.

[0088] In the building 10, the number of dwelling units 11 can be increased in the horizontal direction X2. The building 10 according to the embodiment has a first row of dwelling units 11 including a first dwelling unit 11a lined up in the vertical direction X3, and a second row of dwelling units 11 including a third dwelling unit 11c lined up in the vertical direction X3. A third row of dwelling units 11 lined up in the vertical direction X3 may be further added to the building 10. For example, the third row similar to the first row may be located on the opposite side of the second row from the first row.

[0089] The shielding portion 17 may be omitted from the building 10. In the building 10 of this modification, a handrail is provided at the end of the overhanging portion 13 in the lateral direction X2.

[0090] In the building 10 according to the embodiment, the upper opening 22 is provided so as to overlap the overhang 13 of the roof overhang 21 on the top floor, but the upper opening 22 may also be provided in a portion of the roof overhang 21 that overlaps with the overhang 13 on the floor immediately below the top floor. In this modification, multiple routes for the drone 30 to enter the overhang 13 on the floor immediately below the top floor can be secured.

[0091] The rooftop shielding unit 23 may be manually switchable. For example, when the drone 30 approaches the building 10, the drone 30 transmits a signal to the guidance device to notify the resident of the apartment 11 on the top floor of the approaching drone 30. The resident of the apartment 11 on the top floor operates the rooftop shielding unit 23 when the drone 30 approaches the building 10.

[0092] The drone port 24 does not have to be provided on the projection 13.
