Description

[Technical Field]

[0001] The present invention relates to a house having two or more floors. [Background technology]

[0002] A home needs to provide relaxation and healing to its occupants, and residents are more likely to feel this way when they gaze at the sky or plants, or play with pets.

[0003] In relation to the present invention, Patent Document 1 describes a modular house with a rooftop where gardening can be done. The rooftop of this modular house has four drainage outlets that are connected to outdoor drainage pipes installed on the exterior wall. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Utility Model Registration No. 3106849 Summary of the Invention [Problem to be solved by the invention]

[0005] When a house is surrounded by tall buildings such as apartment buildings, residents are concerned about being seen from outside, even when they are in their rooms, and are unable to fully relax or feel at ease. On the other hand, if a privacy wall is installed in a house to block out views from outside, the outside light will not enter, and the room will become dark.

[0006] The present invention has been made in consideration of the above circumstances, and its object is to provide a house having a space on the top floor where residents can easily feel relaxed and comforted. [Means for solving the problem]

[0007] (1) The house of the present invention is a house of two or more stories, and is equipped with a balcony that is rectangular in plan view and is located on the top floor, four indoor spaces located on each of the four sides of the balcony, and four windows located between the balcony and the four indoor spaces.

[0008] In the above house, the balcony is surrounded by four indoor spaces, and four windows are located between the balcony and the four indoor spaces, allowing natural light and breezes to enter the four indoor spaces while blocking views from the outside. Residents can see into the indoor space on the other side of the balcony from the windows, making the space feel larger. By providing a privacy-enhancing balcony on the top floor, a house can be provided with a space on the top floor where residents can easily relax and feel at ease.

[0009] (2) The four indoor spaces may be connected to adjacent indoor spaces.

[0010] This configuration allows residents to move around the balcony only through the interior of the building.

[0011] (3) At least one of the windows may be a bay window.

[0012] With this configuration, residents can go out to the balcony through the bay window, which allows for ample natural light and breeze to enter. Also, if multiple windows are bay windows, residents can use the balcony as a passageway.

[0013] (4) All of the above windows may be bay windows.

[0014] (5) The balcony may be provided with a drain outlet, and a drain pipe connected to the drain outlet may be located inside the interior wall of the floor below the top floor.

[0015] With this configuration, the drain pipe can be hidden inside the interior wall, allowing water to be drained from the balcony.

[0016] (6) The interior wall may have a recess capable of accommodating a display.

[0017] This configuration results in a natural looking interior wall. [Effects of the Invention]

[0018] According to the present invention, a house can be provided that has a space on the top floor where residents can easily feel relaxed and comforted. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0020] Hereinafter, a house according to an embodiment of the present invention will be described with reference to the drawings. Note that the embodiment described below is merely an example of the present invention, and it goes without saying that the embodiment of the present invention can be appropriately modified without departing from the spirit of the present invention.

[0021] As shown in Figure 1, the house 1 according to this embodiment is a two-story house. In the following description, when the house 1 is viewed from the front, the left side is referred to as the "left," the right side as the "right," the front side as the "front," and the rear side as the "rear." The direction connecting the left and right sides is referred to as the girder direction 5, and the direction connecting the front and rear sides is referred to as the beam direction 6.

[0022] [2nd floor configuration] As shown in Figure 2, the second floor of the house 1 mainly includes rooms 11 to 14, a balcony 15, a kids' corner 16, a walk-in closet 17, a hallway 18, a bathroom 21, a laundry room 22, and a sanitary area 23. A staircase 10 connecting the first and second floors is located at the rear of the house 1. The top of the staircase 10 is connected to the rear of the room 11. In Figure 2, the part marked with the reference numeral 24 is the eaves of the entrance 54, and the part marked with the reference numeral 25 is the eaves of the living / dining room 51 on the first floor.

[0023] Room 11 is located to the rear right of the second floor. Room 12 is located to the left of room 11. A sliding door 41 is located between rooms 11 and 12. Corridor 18 has a corner 18a midway and has a portion extending in the longitudinal direction 5 and a portion extending in the inter-beam direction 6. The front left portion of room 11 is connected to the rear end portion of corridor 18.

[0024] The kids' corner 16 is located near corner a of the hallway 18. The kids' corner 16 is located after the portion of the hallway 18 that extends in the horizontal direction 5 and to the left of the portion of the hallway 18 that extends in the horizontal direction 6. The room 13 is located to the left of the left end of the portion of the hallway 18 that extends in the horizontal direction 5. A sliding door 42 is located between the room 13 and the hallway 18. A sliding screen 46 is located between the kids' corner 16 and the hallway 18, and between the portion of the hallway 18 that extends in the horizontal direction 5 and the portion of the hallway 18 that extends in the horizontal direction 6. The sliding screen 46 is a transparent or translucent three-panel sliding door. The use of such a transparent or translucent screen partition can create a sense of spaciousness even when the kids' corner 16 is narrow. When the sliding screen 46 is open, the hallway 18 feels wider to residents.

[0025] The bathroom 21, laundry room 22, and sanitary room 23 are located close to each other in front of corner 18a of the hallway 18. The bathroom 21 is located to the front left of corner 18a. The laundry room 22 is located in front of corner 18a. The sanitary room 23 is located to the front right of corner 18a. A door 43 is located between the bathroom 21 and the sanitary room 23. The walk-in closet 17 is located to the right of the sanitary room 23. The left end portion of the walk-in closet 17 is connected to the right end portion of the sanitary room 23.

[0026] Room 14 is located in front of room 11 and behind walk-in closet 17. A door 44 is located between room 11 and room 14. A door 45 is located between room 14 and walk-in closet 17.

[0027] The balcony 15 has a rectangular shape in plan view and is located to the right of the center of the second floor. The balcony 15 is a so-called roof balcony. A roof balcony is a balcony that does not have a roof and uses the roof of the floor below as its floor. While a balcony is generally a part that protrudes outward from a house, the balcony 15 is located inside the house 1, which makes it different from a typical balcony. The balcony 15 can also be considered a courtyard located on the second floor. For this reason, unlike a typical balcony, there is no fence or the like around the balcony 15.

[0028] Room 11, hallway 18, sanitary room 23, and room 14 are located on all four sides of balcony 15. Room 11, hallway 18, and sanitary room 23 are connected indoors without a door. Room 11 and room 14 are connected indoors via door 44. Room 14 and sanitary room 23 are connected indoors via door 45 and walk-in closet 17.

[0029] A bay window 31 is located between the balcony 15 and the room 11. A bay window 32 is located between the balcony 15 and the corridor 18. A bay window 33 is located between the balcony 15 and the sanitary area 23. A wall 35 having a waist window 34 is located between the balcony 15 and the room 14. A sliding screen 46 is located opposite the bay window 32.

[0030] The second floor is an example of the top floor. Room 11, corridor 18, sanitary room 23, and room 14 are examples of four indoor spaces located on each side of balcony 15. French windows 31 to 33 and waist window 34 are examples of four windows located between balcony 15 and the four indoor spaces. The four indoor spaces are connected to adjacent indoor spaces.

[0031] Room 11 is used, for example, as a work room. Room 12 is used, for example, as a master bedroom. Room 13 is used, for example, as a children's room. Room 14 is used, for example, as a theater room. Note that the uses of rooms 11 to 14 are not limited to the above examples. Residents may use rooms 11 to 14 freely according to their preferences. Plants can be placed on balcony 15. Residents can place potted plants, planters, etc. on balcony 15 according to their preferences.

[0032] [First floor configuration] As shown in FIG. 3, the first floor of the house 1 mainly comprises a living / dining room 51, a room 52, a hallway 53, a hallway 54, a shoe closet 55, and a storage room 56. The living / dining room 51 is a room that occupies most of the first floor and is located at the rear left of the first floor. The room 52 is located to the right of the living / dining room 51. The rear left portion of the room 52 is connected to the rear right portion of the living / dining room 51. The hallway 53 is located to the front left of the center of the first floor and extends in the longitudinal direction 5. The right end portion of the hallway 53 is connected to the front left portion of the living / dining room 51.

[0033] The entrance 54 is located at the front left of the first floor and is connected to the left end of the entrance hall 53. The shoe closet 55 and storage room 56 are located at the front right of the entrance 54, adjacent to each other in the beam direction 6. The shoe closet 55 is located at the rear, and the storage room 56 is located at the front.

[0034] An interior wall 61 extending in the longitudinal direction 5 is located between the entrance hall 53 and entrance 54 and the living / dining room 51. The interior wall 61 has a recess 62 capable of accommodating a television 63 (an example of a display) and also has a pipe space 64 inside.

[0035] [Drainage from balcony 15] The balcony 15 on the second floor has no roof and is surrounded by four indoor spaces. For this reason, the house 1 is provided with a mechanism to drain rainwater that falls on the balcony 15 via indoor piping. To prevent the balcony 15 from being flooded even during typhoons or sudden heavy rains, the drainage mechanism from the balcony 15 needs to have sufficient drainage capacity.

[0036] As shown in FIG. 4 , the floor of the balcony 15 has a structure in which roofing materials 114 are placed on beams 115, with a waterproof layer 113 provided on top of the roofing materials 114. The beams 115 extend in the longitudinal direction 5 and the inter-beam direction 6. The roofing materials 114 have a rectangular shape and are positioned on top of the beams 115 in a line in the longitudinal direction 5 and the inter-beam direction 6. The roofing materials 114 are made of, for example, ALC boards. The waterproof layer 113 is formed by placing a waterproof sheet (not shown) on the roofing material 114 and applying a waterproof paint thereon. A plurality of deck materials 111 supported by support members 112 are positioned above the waterproof layer 113. The deck materials 111 have a rectangular shape and are positioned in a line in the longitudinal direction 5 and the inter-beam direction 6.

[0037] The balcony 15 is provided with four drain outlets 101 at the positions shown in Figure 2. Each drain outlet 101 is covered by a cover 102 with multiple holes. The waterproof layer 113 has a downward slope (water gradient) toward each drain outlet 101. Each drain outlet 101 is connected to a drain pipe 103. The drain pipe 103 has a first vertical portion 103a corresponding to each drain outlet 101, a first inclined portion 103b corresponding to each drain outlet 101, a second vertical portion 103c, and a second inclined portion 103d.

[0038] Each drain outlet 101 is connected to the upper end of a corresponding first vertical portion 103a. The first vertical portion 103a penetrates the roof material 114 and reaches below the beam 115. The first inclined portion 103b is a portion that extends in a generally horizontal direction while being inclined below the second-floor beam. The four first inclined portions 103b meet midway below the beam 115, and reach the meeting point 104 shown in Figures 2 and 4. Note that the first inclined portions 103b may pass through the second-floor beam and extend in a generally horizontal direction while being inclined.

[0039] The second vertical section 103c is a section that extends vertically from under the second floor beams to under the first floor beams. The second vertical section 103c passes through the pipe space 64 inside the interior wall 61 provided on the first floor. The second vertical section 103c penetrates the ceiling board 116 of the first floor, passes through the pipe space 64 inside the interior wall 61, penetrates the floor boards 121 and slab 122 of the first floor, and reaches below the beams 123 of the first floor.

[0040] The second inclined portion 103d is a portion that extends in a generally horizontal direction while being inclined below the first floor beam. The second inclined portion 103d passes through a sleeve 132 provided in a foundation 131 of the house 1 and is connected to a rainwater cistern 133 provided outside the house 1.

[0041] When it rains, rainwater passes through the gaps in the deck material 111 and reaches the surface of the waterproof layer 113. Because the waterproof layer 113 has a water gradient, the rainwater flows along the surface of the waterproof layer 113 and reaches one of the drain outlets 101. The rainwater then passes through the first vertical portion 103a, the first inclined portion 103b, the second vertical portion 103c, and the second inclined portion 103d of the drain pipe 103 connected to the drain outlet 101, in that order, before reaching the rainwater cistern 133.

[0042] When viewed from the corridor 18 toward the balcony 15, it appears as shown in Figure 5. Figure 5 shows four covers 102 that cover four drain outlets 101 provided on the balcony 15, respectively.

[0043] [Effects of the embodiment] In the house 1 according to this embodiment, the balcony 15 is surrounded by four indoor spaces, and four windows 31-34 are located between the balcony 15 and the four indoor spaces, allowing natural light and breezes to enter the four indoor spaces while blocking views from the outside. The windows 31-34 allow residents to see the interior of the indoor space on the opposite side of the balcony 15, giving the resident a sense of spaciousness. Because the sliding screen 46 is transparent or translucent and the French window 32 facing the sliding screen 46 is also transparent, residents perceive the kids' corner 16, hallway 18, and balcony 15 as if they were a single space. Providing a privacy-enhancing balcony 15 on the second floor provides a home with a space on the second floor where residents can easily relax and feel at ease. These effects are particularly pronounced when the house 1 is surrounded by tall buildings such as apartment buildings.

[0044] Since the area below the balcony 15 is indoors, a spacious living / dining room 51 can be placed on the first floor. Since the second floor is a private space, the curtains on the windows 31-34 can be left open except when sleeping. Since it is difficult to break into the balcony 15 from outside, there is generally no need to lock the windows 31-34. Residents can feel the presence of their family members in the four indoor spaces to a certain extent. If plants are planted on the balcony 15, the family members will not be completely visible as they will be partially obscured by the plants.

[0045] The four indoor spaces are connected to adjacent indoor spaces, so residents can move around the balcony 15 only through the interior of the building. Windows 31 to 33 are French windows, so residents can exit to the balcony 15 through the French windows 31 to 33. In addition, the French windows 31 to 33 allow sufficient outdoor light and breezes to enter. The drain pipe 103, which is continuous with the drain outlet 101 of the balcony 15, is located inside the interior wall 61 on the first floor, so the drain pipe 103 can be hidden inside the interior wall 61 and drain water from the balcony 15. The interior wall 61 has a recess 62 that can accommodate a television 63, so a natural looking interior wall 61 is obtained.

[0046] [Variations] The house 1 according to this embodiment can be configured in various variations. For example, the house according to the variations may be three or more stories tall. In this case, the balcony, the four indoor spaces, and the four windows are all located on the top floor.
