日本东立石幼儿园Higashitateishi Nursery School

这座幼儿园位于东京葛饰区人口稠密的城市街区。前身是一所破败的公立托儿所，目前正在重建并转为私有，并举行了一场设计竞赛。

This nursery school is located in a dense urban neighborhood in Tokyo’s Katsushika ward. A run-down public nursery school was being rebuilt and transferred to private ownership, and a competition was held to select an architect. 

Aisaka事务所与一家管理公司合作提交了一份提案。比赛要求设计考虑到学校的历史和环境以及当代社会的复杂需求。方案不仅满足了这些要求，同时还包含四个重叠的功能，以确保该建筑在未来的许多年里将继续受到社区的喜爱和使用：这是一座“房子”，孩子们可以在他们的老师和家人们都放心的的环境中自由玩耍；一个“公园”，供孩子们活动身体、发展心智；一所“学校”，在那里他们可以学习欣赏生命和食物的价值；同时也是一座“堡垒”，能够在附近高架河床泛滥和其他灾害期间保护社区。

We submitted a proposal in collaboration with a company applying to take over management. The competition required that the design take into consideration the school’s history and environment as well as the complex needs of contemporary society. Our winning proposal met these requirements while also containing four overlapping functions that ensure the facility will continue to be loved and used by the community for many years to come: it is a “house” where children can play freely in a setting their instructors and families know is safe; a “park” where all students can move their bodies and develop their minds; a “school” where they can learn to appreciate the value of life and food; and a “fort” to protect the community during flooding of the nearby raised-bed river and other disasters.

钢筋混凝土结构由可承受水压的混凝土平板和径向墙柱组成。这座十米高的建筑共有三层，大部分教室在二楼，离地面3.7米，以抵御洪水。为了确保密集住宅区的隐私，以及减少噪音的需要，建筑物的外部三面封闭，并围合出一个庭院。 C形建筑的第四面朝向相邻的公园开放。立面被划分为与周围建筑规模相匹配的部分。在北侧，一层从大楼前的狭窄道路向后退，拓宽了街道，从而避免了早晚高峰时自行车和汽车停下来下车时发生拥堵和事故的风险。

The reinforced concrete structure is comprised of flat concrete slabs and radial wall pillars that can withstand water pressure. The ten-meter-high building has three floors, with most of the classrooms on the second floor, 3.7 meters above ground level, to withstand flooding. To ensure privacy and buffer noise in the dense residential neighborhood, as well as for ease of maintenance, the exterior of the building is closed off on three sides and surrounds a courtyard. The fourth side of the C-shaped building opens toward an adjacent park. The façade is divided into sections that match the scale of the surrounding buildings. On the north side, the first floor is set back from the narrow road that runs in front of the building, widening the street and thereby avoiding the risk of congestion and accidents during the morning and evening rush of bicycles and cars stopped for drop-off and pickup.

该设计融合了多条循环路线，其中一些贯穿整个建筑，让孩子们在平时的玩耍时间里保持参与，而另一些则作为紧急情况下的垂直移动使用，人们在火灾中可以向下逃生，在洪水灾害中可以向上逃生，以确保安全疏散。尤其是一直延伸到屋顶的螺旋坡道和宽阔的楼梯，为应急储物空间创造了空间，并根据年龄调整了天花板高度，而二楼的分层座椅在紧急情况下可容纳200至300人，包括学校的165名学生以及教职员工和社区成员，他们可以在此等待救援。

The design incorporates multiple circulation routes, including some that loop through the entire building to keep children engaged during ordinary playtime, and others for emergency use that move vertically, with people going down in fires and up in flood disasters to ensure safe evacuation. In particular, the spiraling ramp that extends all the way to the roof and the wide staircase create room for emergency storage space and ceiling heights adjusted according to age, while on the second floor, tiered seating can accommodate 200 to 300 people during emergencies, including the school’s 165 students as well as staff and community members waiting for help to arrive.

设计一座既能防灾又充满趣味性的建筑，通过相邻的公园向社区开放，同时尊重邻里和街景，让住户几乎意识不到建筑所扮演的角色变化，这个过程有点像解具有巨大变量的多元方程。此外，团队力求在设计的形式和色彩上达到平衡，确保建筑能够应对灾害和长期的社会变化的灵活性，以及适合托儿所但却不会过于幼稚的外观——即质量与实力兼具的建筑。

Designing a building that is disaster-proof but also a fun place to play, open to the community via the adjacent park but also respectful of the neighborhood and streetscapes, and yet which does not making its users constantly aware it is performing these diverse roles felt a bit like solving a multivariate equation with enormous variables. In addition, we strived to achieve balance in the forms and colors of the design, flexibility to ensure the building can respond to disasters as well as long-term societal changes, and an appearance that is appropriate for a nursery school without being overly childish—that is, a facility that combines quality and strength.
