这座留学生宿舍由约300名国际和日本学生混合居住，是东洋大学为促进国际化而设立的SGU（支持创建超级全球大学）。该场地毗邻2017年开放的东洋大学赤板台校区，与周围的住宅区相比，地势较高。从校园出发的连续坡度在场地内形成了约4米的高差，因此建筑的布局要与地形和周边环境相协调成为规划的重点。

This international student dormitory with a mixed population of approximately 300 international and Japanese students was established by Toyo University as an SGU (Support for the Creation of Super Global Universities) in promoting internationalization. The site is adjacent to the Toyo University Akabanedai Campus, which opened in 2017, and is located on higher ground from the surrounding residential area. The continuous slope from the campus creates an elevation difference of approximately 4 m within the site, so the layout of the building to harmonize with the topography and surrounding environment became the key planning point.

不可避免地要考虑到大型学生宿舍对周围生活环境的外部影响（无论是物理的还是心理的），如遮阳、噪音和同伴的压力。而在内部，需要创造一个充实的公共空间，让宿舍的学生可以积极地相互交流，同时提高规划的效率，最大限度地增加宿舍房间的数量。因此选择了不规则外墙的多边形平面形状，沿着场地形状排列。凭借其最长的周边长度，我们成功地控制了由高度和墙体长度同时引起的压迫感。通过在多边形平面上开设两个采光井的功能，室内被连接成图8的形状，形成一个丰富的公共空间，宿舍的学生可以在这里聚会和社交。

It was inevitable to consider the external impact (either physical or psychological) of the large student dormitory will have on the surrounding living environment such as shading, noise, and peer pressure. Whereas internally, it was required to create a fulfilling common space where dormitory students can actively interact with each other while improving the efficiency of the plan and maximizing the number of dormitory rooms. Therefore selected was a polygonal plan shape of irregular exterior wall that lines along the site shape. With its longest perimeter length, we have managed to control the feeling of oppression caused by height and wall length at the same time. By opening two lightwell functions in the polygonal plane, the interior was connected in the shape of figure 8, forming a rich common space where dormitory students can gather and socialize.

位于整个宿舍的共享空间鼓励各种规模和类型的互动。作为整个建筑的公共区域，一楼有自习室、各种工作室、厨房台面和食堂。生活基础设施，如厕所/淋浴间、洗脸盆和厨房，都被分配在二楼及以上的一个连续的八字空间内。这些生活基础设施是由12个宿舍房间共享的。学习室、榻榻米角和穿插在周边和庭院的公共空间（客厅）中的小型生活空间标志着一个连续的空间，就像一条有丰富的风和自然光的小路，无论学生的基础设施分组如何，这都会促进一个轻松的社区。

Shared spaces located throughout the dormitory encourage various scales and types of interactions. As the common area of the entire building, there are study rooms, various studios, kitchen counters, and a cafeteria on the first floor. Living infrastructure such as toilets/showers, washbasins, and kitchens are all allocated in a continuous figure-8 space on the second floor and above. This living infrastructure is shared by 12 dormitory rooms. Study rooms, tatami corners, and small living spaces interspersed in the common space (living room) around the perimeter and courtyard mark a continuous space like a pathway with abundant wind and natural light, which fosters a relaxed community regardless of students’ infrastructure grouping.

在严格的遮阳限制的场地条件下，为了寻求高效的规划和丰富的生活空间营造，我们提出了融合传统宿舍式的 “单间式 “和 “单元式 “的优点，以提高面积效率。虽然每个共享生活基础设施的小组是由每12个宿舍房间组成的，但小组之间没有任何区别或隔断，这使得共享空间能够通过提供自由进入厨房、学习室等来鼓励互动而不是小组归属。

In the search for an efficient plan and rich living space-making under site conditions with strict shading restrictions, we proposed a fusion of the advantages of both the traditional dormitory style “private room type” for area efficiency, and the “unit-based type” for group formation. While each group that shares living infrastructure is formed by every 12 dormitory rooms, no distinction or partition was created between groups which enabled for a shared space to encourage interaction over group affiliation by providing free access to the kitchen, study rooms, etc.
