Hakusui nursery school
佐倉 / 保育園
Sakura / Nursery school
This nursery school in Sakura, Chiba was planned to accommodate 60 pupils.
Seiyu-Kai, a local social welfare firm specializing in elderly care facilities approached us for this project. The overarching concept for this plan started with an idea: “a nursery school is a large house.”
Surrounded by mountains and forest, the southern area of the site rests on a gentle slope. Putting this topography to use, we designed the school room to resemble a large set of stairs.
One unique feature of this “large house,” for example, is that a 3-year old child is in the same room as a 5-year old and these children of different ages can interact in the wide, one-room space. Additionally, should a 3 year-old child be sleeping while a 5 year old child plays nearby, these differences in rhythm reinforce the "domestic" qualities of this "large house."
Keeping in line with Seiyu-kai's longstanding (26-year) philosophy, we made it a priority to minimize the number of blind-spots within the room in order to keep safety measures as unintrusive as possible.
Utilizing large sliding window frames along the northern and southern faces, along with the space created by the slope, ventilation is created as a breeze draws in from the south of the structure, passes through the forest-like interior pillars making its way upwards before finally blowing out across the terrace on the northern side.
A small pond on the southern end which gathers rainwater as well as water from sprinklers installed on the southward-slanted roof also contributes to the airflow as the water is absorbed into the wind that blows into the structure. This was part of a comprehensive plan to create a space that was inseparable from the environment that surrounds it. We believe that in pursuing the original concept of a “nursery school as a large house” we achieved something not unlike the houses in farming communities that surround it.
Our goal was to create a space that was not only fun for the children but via blending into the nature around it, foster an experience that was greater than the sum of its elements.

隣地で特別養護老人ホームを営む社会福祉法人誠友会が事業主として計画が進められた。計画は「保育園は大きな家である」という考えに基づいている。
周囲を山林に囲まれた敷地は南に緩やかに傾斜しており、それをそのまま利用して階段状に保育室を配置した。
この「大きな家」では、例えば３歳と５歳が互いに意識できる大きな一室空間としている。逆に3歳の子供が寝ていて、５歳の子供がそばで遊んでいるといった生活リズムの違いは、ここでは「大きな家」の特徴として捉えている。
部屋にならないことで起こるデメリットより死角を極力つくらないことを優先させ、段差の安全対策を必要最低限にとどめ、運営する中で対応を講じるという、誠友会が特養で26年培われた理念が引き継がれた。
南面と北面に大きく開放できるサッシと斜面利用した空間を利用した重力換気により、建物に南から呼び込まれた風は林のように林立した柱の空間を高く持ち上げられた北側のテラスへ抜けていく。南に傾斜した大きな屋根面を冷やす井水散水や屋根から伝う雨を受ける南面のジャブジャブ池は、建物に取り込む風の気化装置にする。建築を環境に対して閉じない計画とした。この保育園で目指している「大きな家」は、この地域にかつてあった農家住宅のようなものに近づいたように思う。
この場所でしか感じられない風や、雨や屋根散水の水が南側の庇から滝になって遊べる楽しみが子供たちの原体験として残ってくれれば嬉しい。
