Located in the southeastern part of Hiroshima prefecture, Fukuyama city of Bingo region center city. In the Edo era Tokugawa Ieyasu 's cousin Mr. Katsunari Mizuno flourished as a castle town of 100,000 Goku of rice. Located in the southern part of Fukuyama city near by the ocean, Tomonoura is a scenic spot that was also recounted in the “Manyoushu” as a harbor awaiting a tide from the ancient times, also a part of the Seto Inland Sea National Park designated as the first national park in Japan. Fukuyama City.
This building was built as a residential complex in the office, in a good residential area of Fukuyama city here. The site is elongated in the north and south, gradually rising from the south to the north. The south side of the site was a road of about 4.5 m and the west side was in contact with a road of about 4 m in a narrow place. However, because there was a height difference of about 2 m from the south side road, so the site before the plan was used from the west side road. Therefore, in order to make full use of the features of the site, skipping to change the height of the floor of the entrance, the living room, the dining room by half, while surrounding the courtyard, making a digging parking lot using the difference in elevation with the south side road. The skip floor created a depth in the space, making it a comfortable distance sense space.
And the "floating wall" of the cedar formwork concrete finish which is the biggest feature of this building protects the sense of openness and privacy while staying in the residential area. "Floating wall" is a wall of 3.6 m in height which we made it float from the ground and has a distance of about 1.2 m from the interior. As a result, a margin is created between the room and the floating wall, which changed the light and weather expression of the tree and every moment are incorporated into the space, while securing adequate lighting and ventilation.
The structure adopts reinforced concrete construction, and part of the structure is attracted as a design wall as a cedar board formwork and decorative mold frame finish. The flooring material is Muaga, the ceiling material is Muninga, both are African-origin flooring materials. Wood raised in a region with little rain in Africa is solid, so it is heavy hard and has little dimensional change and can be used externally with confidence. Furnitures are made out of walnuts. The flooring around the water uses inorganic materials such as tiles, glasses at the opening and some of the design walls and floating walls of the room as concrete, and the cedar plate form concrete By copying the cedar board pattern on inorganic concrete material, it fuses together with the wooden materials of the floor, the ceiling, and the fittings, and makes it complement each other.
This building has abundant spaces created by skip floor, floating walls, mountain-picked trees. There is a "margin of beauty" the aesthetic sense peculiar to the Japanese. The remaining gaps will leave a margin in the heart of the household, which will enrich the space.
