From here, section 2 is started. Section 2 is about “boundary”. “Boundary” means the edge between the inner and the outer space and it also means shape ,color and texture. Today's story is about the shape of buildings.

It is said that many children usually draw house with triangle shaped roof when they are asked to draw a picture of house. House with triangle shaped roof is typical and traditional not only in Japan and also all over the world. It's well known that Parthenon and Japanese traditional house in Hidatakayama have both triangle shaped roof. However I asked my students to draw houses freely here in this class 4 years ago. As a result, surprisingly, there were 37 students out of 70, who drew house with triangle roof. On the other hand, there were around 20 students who drew cube box as a house. Obviously it is the fact that with declining in the number of wooden houses, the number of houses with gable roof are also decreasing and nowadays many people live in the condominium building. It is clear that there is an unmistakable influence of modernism from the point that around 30 percent student have a cube box house as their original image of houses.

In the early 80's when these students were born in, there were still dying modernism architecture around the town, though post-modernism was just spreading in the world. And in the 90's when they become aware of the things around, post-modernism had been already over and a lot of modernism architecture revived, that is “cube box”, around the world. Therefore, in fact, houses, sort of architecture, could be more cube for people who were born in the early 80's rather than you, late 80's people.

Actually the idea that cube box, a kind of Descartes's grid, was denied already existed before post-modernism appeared. Paradoxically I would pick up Adolf Loos as the head of this idea. Because I think that he tried to make not a box but a bag to wrap a person, not a box. And this idea was inherited into Paul Virilio、Claude Parent, who tried to deconstruct 90-degree angle philosophically and nowadays leads to biology via deconstructivism. This flow show an consecutive thought of denial for square things. It is just like water vein. Again, these architecture are based on the premise that architecture should be bag for people, which is a usual and basic root of architecture, not be cartesian grid.
