MVRDV has won a competition to redesign the Tancheon Valley and waterfront in Seoul with “The Weaves”, a design that knits together a tangle of pedestrian and bicycle paths, natural landscapes, and public amenities into an appealing, playful, symbolic landscape. Commissioned by the government of Seoul, the design introduces an intense combination of nature and human activity in the midst of the city. In announcing the winner of the competition, the jury described how MVRDV’s design “shows great balance between ecology and the creative program, and offers an outstanding strategy to provide urban event spaces and resting areas to citizens, encouraging many different target users to take advantage of the site.”

Located between Seoul’s former Olympic Stadium in the Jamsil district and the rapidly growing central business district in Gangnam, the point where the Tancheon River joins the Han River is currently dominated by surface car parking and elevated highway structures. A kilometre-long stretch of the Tancheon River will be completely transformed by the design, as well as a significant stretch of waterfront along the Han River. The central concept of “The Weaves” was to intertwine three aspects of the landscape: natural ecosystems, access for pedestrians, and elements of public program where activities can take place.

The first step in this plan was to return the river to a more naturalistic state, replacing hard landscaping with lush green riverbanks, and changing the river from a straight canal to a meandering stream. The design softens the banks of the river with carefully selected native vegetation, including aquatic plants at the river bank to further blur the boundary between land and water, as well as water retention pools, islands, and purification streams that all contribute to a healthy waterfront ecosystem.

The second part is the development of a network of winding interconnected paths that allow easy pedestrian access throughout the waterfront, creating opportunities for visitors to encounter the natural ecology in a variety of ways. These paths are not only confined to floor level, though, often peeling away from the ground to cross over other paths, form a bridge over the water or roads, or connect to a pedestrian route at a higher level. This network incorporates existing infrastructure on the site: in response to the government’s plan to decommission and demolish sections of the site’s highways, MVRDV instead proposed to keep the structures and transform them, echoing the hugely successful Seoullo 7017 project that MVRDV completed in central Seoul in 2017.

这种错综复杂的路径还引入了作为第三个设计元素的公园的公共项目。这些路径交错重叠、迂回曲折、起起伏伏，形成了广场、观景点、圆形剧场、咖啡馆和其他便利设施，也让公园有更为强烈的立体感。曾参与过Seoullo 7017项目的MVRDV创始合伙人Winy Maas表示：“首尔正在以惊人的速度将灰色和过时的基础设施改造成充满活力的绿色景观和社交空间。The Weaves是一个将景观与多种不同寻常的通道相结合的设计。它以独特有趣的方式让人想起缠结的丝绸线，以回应蚕室区作为著名丝绸生产地的历史身份。整个项目仿佛一首交织的诗，而人与车在其中的运动就像山间未曾停歇的水流。”

This tangle of paths also introduces the third element of the design, the park’s public programme. The paths overlap and intersect, split and recombine, twist and turn, and rise and fall to create plazas, viewing points, amphitheatres, cafés, and other amenities. The result is a public park with a dramatic three-dimensional character. “Seoul is taking amazing steps to transform grey and obsolete infrastructure into lively green and social spaces”, says MVRDV founding partner Winy Maas, who also worked on Seoullo 7017. “The Weaves is a design that introduces natural landscape combined with exceptional, varied access. It also responds to the local identity. Jamsil is known for its history of silk production and the design recalls the tangled silk threads of its past in a unique and playful way. It becomes an intertwining poem where movement becomes landscape poetry.”

A highlight of The Weaves is the pedestrian bridge connecting the Gangnam district to the Olympic Park. A bundle of paths rise up from the river below to form a crossing that incorporates a viewing platform, a small tribune, and a media floor. This bridge leads to a path that cuts past the Olympic Stadium, curving around to eventually end at the “tree pier”, a diverging cluster of paths extending into the Han River.

其他值得注意的公共功能包括“Event Dome”，这是一组凸起的交叉路口形成的一个观景结构和下方半覆盖的活动空间。家庭游乐场的小径被磨成许多线条，以形成攀爬结构、长椅和动物形象的雕塑。“Seoul Water Path”是一段延伸到汉江水面上的道路，以循环的方式拼出“Seoul”一词。在现存的建筑中，一条沿丹川河西侧的高速公路坡道将被改造成一个凸起的公园，并与其余的道路网络相连。穿越丹川河河口的一段高速公路将被大面积拆除，但其中一部分会被保留下来用作自行车中心。
Other notable public functions incorporated into the path include the Event Dome, a group of raised crossing paths that form a viewing structure and a semi-covered event space underneath; the family playground, where the path frays into many lines that form climbing structures, benches, and animal figures; and the Seoul Water Path, a section of path that extends out over the water of the Han River to spell the word “Seoul” in a looping script. Of the existing structures preserved on the site, one highway ramp running along the western side of the Tancheon River will be transformed into a raised park and connected to the rest of the path network. Another section of highway crossing the mouth of the Tancheon River will be largely demolished, but a piece of it will be preserved to host a cycling hub.
