CONCEPT
新宿御苑近くに位置する保育園の計画である。敷地には、大きなクスノキやコブシが数本現存していた。これらの樹木を残しながら更に樹木の様な建築をつくり、敷地全体を森の様につくれないかと考えた。
敷地面積が限られていることから、4層をスキップフロアーとしてらせん状に上部へと連続させ、中心となる多目的ホールを介して空間内部で各所が見渡せる計画となっている。乳児から幼児まで子供たちの成長に合わせた部屋の設えと外部との関係性を設定しながら計画を行った。そして空間の内外の各所で、水、光、土、風による自然現象が起こり、子供たちが五感を通して様々な体験をできるようにと各部の計画を行っている。
また地上の園庭から屋上までを連続させた人工地盤として考え、最上部で雨水を貯め、下部まで自然に流下する計画である。各所に果樹等の植栽を施し、ビオトープを形成する。
石垣に囲われた敷地全体が、森の様に樹木の落ち葉を貯め、腐葉土をつくる場として計画した。各階の床は幹柱から枝柱を出し、更に幹柱の頂部からワイヤーで吊り、幹柱は鋼管杭として地中まで連続して伸び、地熱を採熱する装置を兼ねている。

It is the scheme of a nursery school located near Shinjuku Imperial garden. On the site, big camphor tree and several Kobushi magnolia existed. Build architecture still like trees, leaving these trees, and build the whole site like forest.
Since plottage is restricted, four layers are made to follow the upper part spirally as a skip floor, and it has become a plan which can overlook every place inside space through a main multipurpose hall. The program planned it while setting the equipping with of the room to the growth of children and a relationship with the outside from a baby to an infant. And water, light, soil, a natural phenomenon caused by the wind are caused in each outside place among space and plan each part when it be possible for children in various experiences through the five senses.
Moreover, it is think as artificial ground which from playground to the roof was made to follow, to collect rain water at the topmost part, and flow down naturally to the lower part. A fruit tree etc. are planted in every place and a biotope is formed.
The whole site enclosed by the stone wall collected the fallen leaves of trees like forest, and made the plan as a place which builds leaf soil.
The floor of each story took out the branch pillar from the trunk pillar, and also it hung from the top part of the trunk pillar with the wire, and the trunk pillar was continuously extended to underground as a steel pipe pile, and serves as the equipment which extraction heat of the earth. I imagine that a town of Shinjuku becomes the forest someday, and it is a part of the forest and the plan of the nursery school where it is.
