Thinned materials from forests are, now, an environmental issue as the result that human beings destroyed the balance of nature. Our trial realizes pavilion architecture only by using wasted thinned materials in experimental small scale. This ”azumaya” (arbor or folly in English) architecture of today, consist of minimum required function and experimental space, shows the active and effective usage of the wasted thinned materials in forests that they are regarded as unsuitable materials for building because they are thin or bended.
We use two types of cedar wood in sectional size, 38mm by 89mm and 51mm by 89mm, and two of each type is bolted in L shape to have a strength and quality. These two L shaped materials are accumulated having 13mm gap on each, forms the module of 89mm by 178mm sectional size and 300mm length. Accumulating with gaps and tightened by tie rod, body of the building is integrally assembled from the wall to the roof. The gap in the wall takes light as well as insulates the air when glass is inserted. This space created by novel construction system has sufficient strength by utilizing the light property of wood, and gaps on the homogeneous wall provide random lighting to the space. We believe that this novel acquired wooden space provides a variety of lighting expression in time to time and season to season.
This construction system is an embodiment of the result of four years study and experiment on strength such as internal shear stress and external bending stress. The system has a potential to be able to construct buildings in narrow space in the urban area without machinery, as well as to popularize a view of coming wooden structure.
The project is implemented at Tokyo university Komaba campus where is organized widely open for regional community. So that this “azumaya” architecture of today is planned to be used by students in various purpose as well as used as exhibition place to announce promotion of forestry operations. The place should not wear an image of a part of governed school, but be a park that exists naturally in the area with a less image of order or ruling of architecture. This is our aim to accomplish Space Architecture.
”A tree makes surroundings livery and bright.” This is a differential character of the material. We utilized the character as much as possible. This “azumaya” architecture of today does not separate inside and outside, and is expected to be variably used for a promotion of domestic materials to just a resting space. And finally this architecture, which utilizes domestic thinned materials, shows one way of regeneration the balance of nature we have destroyed
