屋顶广场，首尔 / HG-Architecture

首尔市目前正在对一些空间拥挤的地区进行立交桥下空间改造，从而为当地社区提供一个公共休闲场所。作为试点项目，本次改造用一个充满生机与活力的环境来代替了桥下原本阴暗荒凉的空间，也进一步改善了当地的生活环境和城市景观。

The city of Seoul is in the process of creating a public space for local community to use in the area by utilizing the lower space of the overpass, which is relatively unusable in cities with insufficient space. This project is a pilot project, and it is a project to improve the living environment and urban landscape of the region by changing the underpass, which was shadowy and desolate, a lively and vibrant environment.

本次项目所在的Imun立交桥下部空间，是铁路立交和公路立交这类大型基础设施的底部交叠。城市规模和周边街道被它们切断，铁路公路之间的目的地也被分隔开来。这样一个安静的空间，让人仿佛觉得时间也就此停止。本项目旨在通过“屋顶”等建筑元素，来将这样一个城市闲置用地及其周边断裂的空间相连，使之成为可以举办各种文化和体育活动的社区中心。

The site, the lower space of Imun-overpass is a lower space of a large infrastructure where railway overpass and road overpass overlap. The city’s scale and surrounding streets were cut off by the overpass, and the destination between them was isolated and left as a static space as if time had stopped. This project aimed to become a center of local community as a community space for various cultural and sports activities by connecting the disconnected periphery by using an architectural element, ‘The Roof’, on such an unused place in the city.

“屋顶广场”是在上下部之间形成的中线空间，并在屋顶元素的作用下成为了新的公共空间。被高架切断的上部空间沿东西方向交替打开，下部空间将邻域拉入站点，并将站点扩展到邻域。屋顶上部为文化活动、休闲娱乐和简单的运动空间。下部在白天是当地人的庇护所，晚上则成为附近餐馆和小贩的户外露台咖啡馆。总的来说，它就像一个随时间变化的当地居民生活庭院。

‘Roof Square’ is a Mid-Line space made in the upper and lower parts, creating a new public space by using a roof. The upper space alternately opens in the east-west direction, which is cut off by an elevated road, and the lower space pulls the neighborhood into the site and expands the site into the neighborhood. On the top of the roof is a space for cultural events, relaxation, and a space for simple exercise. The lower part of the roof is a shelter for local people during the day and an outdoor terrace café for nearby restaurants and vendors at night, and it becomes a courtyard where locals’ daily lives change over time.
