A public toilet which was completed in Ibukijima Island of Setouchi Inner Sea. It was one of artworks in Art Setouchi Triennale 2013.
Periphery / Center
In the traditional local house in Ibukijima Island, the toilet is mostly established in a small cottage separated from the main house. In Ibukijima Island, the toilet is a peripheral space that is repelled and excluded from the main house.
The relation between the main house and the separated cottage resembles the relation between the main land and isolated Ibukijima island or between a big city and a remote district somewhere. Now, Ibukijima island is only connected with liner from Kanonji city of the main land, and the small isolated island serves as the periphery of the main land and the country of Japan.
However, if it goes back, in Edo period, Ibukijima island was a place where liner connected directly with capital and the upper fashion came immediately, and, as a vestige of that period, the capital dialect of the old time remains.
Once, it was the independent small center of Setouchi Inland See.
House of Toilet tends to change the peripheral space into the center of Ibukijima Island and to give intensity to Ibukijima Island that has been used as the periphery.
When the toilet repelled from the main house gathers, nestles up to one and forms a house, it comes to have the power as a core.
Locality / Internationlity
To the house, the time peculiar to Ibukijima Island and the relation with the world centering on Ibukijima Island was overlaid.
According to the solar orientation at 9:00 a.m on the day when three traditional ceremonies are held and the day of the summer solstice and the winter solstice, the slits of the natural light pass in the architecture. When the ray of sunlight passes in the house at 9:00 a.m once per year, the locals konw the visit of the season.
Meanwhile, the lines of the natural light which go to the major cities of 6 continents (Tokyo, London, Nairobi, New York, San Paulo, Sydney) by the shortest distance from Ibukijima island also pass in the architecture.
I considered that Ibukijima island regains the self-respect of the once by being conscious of relation with the world.
When the relation with the world ( Internationality) is added to the identity of Ibukijima Island ( Locality), the direction of the natural light of 2:00 PM would be founded to coincide with the direction of New York and they aware that the internationality exists along the extension of the locality.
Moreover, the place where the axis of these six angles crosses is the coordinates point that indicates the position of Ibukijima island, so, the relation with the world is also the locality itself.
Relation with the landscape of Ibukijima island
The exterior appearance resembles the ordinary local house of this island.
I didn't design it with the form where the contemporary architecture abruptly appeared.
It is a consideration to the landscape of the island where the traditional sign remains.
The inclination of the roof is united with the surroundings and the color of the outer wall is based on color investigation of the local house of the island.
The alley created between 3 buildings that were cut by the slits of the light goes to the alley of Ibukijima island like a maze.
The wall of the alley and the interior wall of lavatory are based on the image of the burnt cedar board as a typical finish but are not necessarily the same as it. For example, the polycarbonate corrugated panel that reflects the scenery is layered on the board. Those have a delicate difference by which they catch their mind somewhere.
In the booth at the depth of the indoor, the big opening is opened on the roof.
The natural light and the rain fall indoors. It is as if they have looked up from the bottom of the local well for collecting rain water peculiar to the island lack of the water.
I hope that the visitor who starts for an island walking after a short breath in House of Toilet will find easily the peculiar landscape of Ibukijima island and the locals is re-conscious of the identity of the island that they used to seeing and, therefore, have forgot to see.
