The Children’s House of Satoyama
The project was to combine an existing nursery school with a nearby preschool and reconstruct it as a child center. The site is located in the middle of a mountain which slopes gently toward the sea. The surroundings were once a developed residential area. The new child center is made of wood, and the idea was to create a “Satoyama house” for the children that they would be embraced by the mountains.

Under the condition that the construction would be carried out while using the existing preschool on the southeast side of the site, it was decided that the new child center would be arranged in an L-shape surrounding the southeast playground (the part of the existing preschool). The playroom and the classroom for 3 to 5 year-olds are located on the north side, and the entrance, the main office and classroom for 0 to 2 year-olds are located on the west side.

The appearance like a Satoyama village
Each classroom has its own roof to make it seem like a village of Satoyama. The younger children’s house on the west side has a square roof, and the older children’s house has a gabled roof with north-south ridge. There is another roof below them to connect the entire area from the nursery to the playground. In front of the nursery rooms run a corridor and an open veranda both 1.8 m wide, and one more 1.8 m wide space under the eaves. As in the old days of farmhouses, the children come in and out from the veranda to play on the playground. They would also sit on the veranda, which is shaded by the large eave, and watch other children play outside.

The children’s house is located at the back of eave about 6m deep, which with high windows on the north-south gable ends to allow natural light and air to flow in, creating a bright and hygienic environment.

While it is a wooden structure, the earthquake resistant elements are distributed and arranged similar to a reinforced concrete structure. Because of this, the brace and walls were left out of the portion of the eave facing the playground so as to create the appearance of a private house in Satoyama.
