It is new unification school building of 3 local elementary schools planned in site of existing junior high school.

By locating new school building of wooden one-storied house in the east side ground of existing school building, children who varied in build difference established ground for the lower grades that could live a life safely.

Rain which it rains on roof of indoor athletic ground is collected in retention tank of floor lower pit of classroom via rainwater tank and uses as lavation of restroom.


"We bundle up, and stack materials" adopt structure system which put angle brace together pure materials of cedar as structure plan and, using material that it is 10m or less about constant shaku materials of 4m and 6m, indoor athletic ground in the classroom, constitute beam and two angle braces in combination with three, four depending on span and stress.

It merged indoor athletic ground with school building and used wood of 700㎥, but it was that process of processing relied on technique of the carpenter leader. Because it is system which angle brace turns angle, and supports such a roof in kan*hai, means of junction of each wood are different.
