This kindergarten is about 45 minutes by Shinkansen train from Osaka and surrounded by a newly developed residential area. The structure consists of concrete boxes between each of the rooms and a wooden roof that ties them together. The shell-form roof is made of triangular continuous surfaces; its structural strength and geometrical consistency permits great freedom in designing of the necessary spaces. This structural system uses 2.5 m wooden beams and hexagonal metal fittings, factory-made and only assembled on the site. The integration of the wooden trusses and concrete boxes is geometrical but varied, a structure with rich in expressive effects.
