Seoul Maru, the sloped roof of Seoul Hall of Architecture & Urbanism, was planned to revive the historic urban context of Seoul’s the oldest district behind Sejong-daero. The empty architectural slope was aimed to allow the surrounding urban fabric to be brought in. However, this architectural slope could not be read clearly due to the vaguely planned furniture and the unexpected level difference with the parking area of the adjacent Seoul Anglican Cathedral. It was believed that ‘public intervention’ needs to be an architectural proposition that can recall the historical contexts of the surrounding area. This project is an experimentation to explore new types of public space as well as a landscape that can experiences the existing physical sloped plane clearly, rather than erecting splendid architectural form or volume in the historic area of Seoul.

在竞赛阶段产生的“建筑弹球机”物理模型是在斜坡上创建新公共空间和城市游乐场的一种实验手段。发射的球在具有图案和设施的倾斜场地上上下移动，代表首尔的标志性地点和建筑。发射球的玩家成为弹球巡回活动的表演者，观看的人成为观众并参与这场表演。此外，在已完成的9m x 18m的巨型户外弹球机中，使用者可以直接到游戏场地上，与测试人们移动速度的设施进行游戏与互动。游戏场地变成了玩耍的舞台，使用者也以自己的方式行走、奔跑、跳舞、坐着、休息，成为新公共表演“集体城市游戏”的参与者。

The physical model ‘Architectural Pinball Machine’ produced during the competition stage was a means of experimentation for creating a new public space and urban playground at the slope. A launched ball travels up and down through the inclined game field with printed graphics and objects placed on it, expressing symbolic places and buildings of Seoul. The player who launches a ball becomes the performer of the pinball’s traveling event, and the colleagues who watch it become the audience and participate in this performance. In addition, in the completed 9mx18m giant outdoor pinball machine, users directly come up on the game field, then play and interact with the objects that detect people’s motion. The game field becomes a stage for play, and visitors become participants in a new public performance called collective urban play through the acts of walking, running, dancing, sitting and resting in their own way.

Material stores for the future
该项目是通过与创意工匠、工程师、制造商、材料研究员、家具制造商合作完成的。设计、制作和安装用了短短不到三个月的时间，并且Studio Heech的设计师参与了整个制造过程。自设计之初，可持续性就被视为关键问题。该项目在首尔Maru安装三个月后，会被重新安置到其他地方，而不是被处理掉，从而获得持续的生命力。这意味着该项目的最终成果需要是可持续的、制作精良的产品，而不是仅为三个月的临时安装而生产。其组件和接头的设计也便于组装和拆卸，并且几乎所有元件都是在现场预制和安装的，可以减少施工现场对环境的影响和碳排放。2.5厘米厚的高性能混凝土（UHPC）面板的重量和体积相对于其强度而言较小，因此对环境产生的影响较小，是易于组装和拆卸的选择。1m x 2m的UHPC面板和钢制下框架在堤川工厂制造并在现场安装的。

The project was completed through collaboration with creative artisans, engineers, makers, material researchers, furniture makers. The design, production and installation took place in a short period of less than two months, and the Studio Heech’s makers participated in the entire fabrication process. From the initial design stage, sustainability was regarded as a crucial issue. It was believed that sustainable vitality could be obtained when relocating to another place rather than being disposed of after three months installation in Seoul Maru. This meant that the final outcome of the project needs to be sustainable well-made products rather than being produced for the only temporary installation for three months. The components and joints were designed for ease of assembly and disassembly of this purpose. Almost all elements were prefabricated and installed on site in order to reduce the environmental impact and carbon footprint generated at the construction site. 2.5cm thick high-performance concrete (UHPC) panels, which has a low environmental impact due to its small weight and volume compared to its strength, were a choice for ease of assembly and disassembly. The 1m x 2m UHPC panel and the steel lower frame were manufactured at the factory in Jecheon and installed on site.

In addition, the proposed objects were made using various recycled/upcycled materials. The structural timber beams (old wood) that had been stored in the warehouse for many years were used as structural support for signage and furniture. Bio-plastic objects using duck egg yolk that is discarded by pharmaceutical companies, and eco friendly MDF boards that have no harmful emits but also have durable and stable enough quality for use outside have been used as a finishing material for various furniture and objects.

‘Not a venue, nor a pavilion’
The idea of the Seoul Urban Pinball Machine was drawn from the initial question, what the public space and public installation project need to be like after the pandemic, which our city has never experienced. The Seoul Urban Pinball Machine is planned as a new public space, urban playground, public furniture and landscape where the existing physical slopes of the Seoul Maru, various materials and textures are experienced. People go out to the outdoor space to enjoy pinball games in their own way, take a walk, and experience and encounter objects made of eco-friendly materials. This is an attempt to represent a new perspective of our city after the pandemic and transforms Seoul Maru into a place where the civic community shares its confidence in urban resilience.

The Seoul Urban Pinball Machine, which will be dismantled, move and re-installed three months later, like the Masques project, in which the characterized architectural objects and devices created by John Hejduck continue the narrative while traveling through cities such as Berlin, Hanover, and Lancaster. We look forward to see new urban stories that will be written by the Urban Pinball Machine.
