架构师提供的文本描述。KB青年步骤将空间集团1968年设计的KB Kookmin银行的Seokyo分馆改造成了年轻人的文化设施。这座建筑中包含了以楼梯广场的形式对社会作出贡献的想法，它将邀请一种城市风格进入该建筑，并向一个没有广场空间的城市开放一座私人银行大楼。主要设计概念可归纳如下：

Text description provided by the architects. The KB Youth Step has transformed the Seokyo branch building of KB Kookmin Bank, designed by Space Group in 1968, into a cultural facility for young people. This building contains within it the idea of contributing to society as a public space in the form of a stair plaza, which will invite an urban style into the building and open a private bank building towards a city in which there is no available room for a square. The main design concepts can be summarized as follows:

这一设计的出发点是没有公共空间，在这个地区散步时没有提供座位的方便。KB Kookmin银行的小型私人建筑的指导思想是在Hongik大学附近插入一个梯田作为公共空间。其目的是使新的KB青年踏步成为一个向城市开放的公共空间，而不是一个封闭的区域，并让金融机构的累积资本为公众利益服务，而不仅仅是为某些个人或成员服务。从一楼到二楼的楼梯广场已被规划为活动场所，人们可以在其中休息、用作聚会场所，或进行各种活动，如街头表演和街头表演。

Publicity The starting point of this design was the idea that there is no public space offering the convenience of seating when on a walk in this area. The guiding concept for the small private building of KB Kookmin Bank was to insert a terraced element to serve as a public space near Hongik University. The intention was to make the new KB Youth Step a public space open to the city rather than a closed area, and to let the accumulated capital of the financial institution serve in the public interest rather than for only certain individuals or members. The stair plaza, reaching from the first floor to the second, has been planned as a place for events, and as a space in which people can take a rest, use as a meeting place, or perform various activities such as busking and street performances.

在这座建筑中，拓扑学利用建筑和城市的方法来创造空间结构，以实现一种宣传感。楼梯折叠到二楼，再折叠到屋顶，形成两个室内楼梯空间和两个室外楼梯广场。楼梯从地下室到屋顶形成一个连续的循环，自然吸引城市的循环进入建筑物。一个模糊的楼层划分混合空间和建筑是与城市的拓扑整合。将建筑物与城市连接起来的拓扑空间在向公众和城市开放时，实现了一种拓扑宣传，而不是作为一种私人空间。

Topology In this building, topology plays with architectural and urban methodologies to create spatial structures that realize a sense of publicity. Folded to lead to the second floor and folded again to get to the rooftop, the stairs create two indoor stair spaces and two outdoor stair plazas. The stairs create a continuous circulation from basement to rooftop, naturally attracting urban circulation into the building. An ambiguous division of floors mix the spaces and the building is integrated with the city topologically. Topological spaces connecting a building with the city realize a kind of topological publicity when open to the public and the city, rather than used as a private space.

历史的历史要被尊重，记忆要保留下来，保持建筑物的外观与城市的记忆相联系，吸引城市的结构来创造空间结构。人们可以通过历史的轨迹和框架来观察这座城市。室内直接楼梯、立柱、砖墙和地板也被保留下来，让游客体验过去的痕迹。

Historicity History is to be respected and memory to be preserved by keeping a building’s façade associated with the memory of a city and attracting the urban fabric to create a spatial structure. People can look at the city through the trace and frame of history. The indoor direct stairways, columns, brick walls and floors are also preserved to allow visitors to experience the traces of the past.

灵活的室内楼梯空间，配有折叠式屏风，不仅可用作表演厅和剧院，还可用作书吧、休息场所和阅览室。室外楼梯和屋顶空间可以成为各种用途和用途，如沉思、放松、表演、街头表演、聚会等等，都实现了邀请城市生动活泼的概念。

Flexibility The indoor stair space, equipped with a foldable screen, can be used not only as a performance hall and theatre but also as a book café, resting place, and reading room. The outdoor stairs and rooftop space can become a place for various purposes and uses, such as contemplation, relaxation, performance, busking, parties, among others, all realizing the concept of inviting the  liveliness of the city into the Hongdae area.
