Building summary

It is one facility which Toyono elementary and junior high school utilizes junior high school site, school building of neighborhood in rebuilding of elementary school, and performed extension and/or alteration-shaped combined elementary and junior high school. We used classroom and gymnasium in common and maintained effectively, and educational effect to cope with was expected by consistent education especially to gaps such as school refusal in the first year of junior high school. Existing junior high school performs seismic strengthening and partial repair. Koizumi atelier and joint venture of SDA architecture design won design.


School building ridge and gymnasium ridge which run side by side with two lines on junior high school site, and were located exist. New school building becomes form filling gap becoming the rest. As a result, it is plane shape surrounded with gentle curve that envelope has external form of existing structure. We build one piece of roof with slow ups and downs over the plane. Ups and downs were arrived at from the ceiling height along function of the stock. Even if roof builds needle of wooden laminated lumber over one direction and is where in the school building, lengthening roof is seen in various directions. We bring about sense called bottom of one roof at the same time as spread is felt and are roof breeding a sense of unity of child, student.

Format enclosing space with this gentle curve is thing which fixed its eyes on temporal axes. In the case of rebuilding of the next junior high school school building, trace of conventional school building will be left outside of school building built this time.

We tie old and new buildings physically and join feeling of primary and secondary student together. And it is school architecture "tying" playing its part joining memory together to the future.
