city border as in 1946

Once peripheral, now in the middle of the city. Site is dominated by infrastructure. Insular characteristic of neighborhoods with large void of former railyard.

Site itself is hierarchically related to the Hangang river, tied to metro region by urban rail, bordered with main traffic throughfare, and is a part of poly-centric city.

Brief:ageing

Ageing of population is imminent. Yong society will become more diverse,...

Brief:density

6/25

The quantitative objective is to house 100’000 people on 100ha. Though designated area is 2.5 sq.km2 , hence it is possible to elaborate existing structures.

Condition is a state, shape, status. In other words, it describes the performance of the site, actual shape, ongoing process and possible fate and after comprehending it allows to come up with diagnosis.

Conditions:landscape

8/25

Landscape as a realtionship of human life with nature is expressed in Sansu-hwa, traditional Korean landscape painting, which literally means mountain-water .

Conditions:landscape

9/25

Sansu also means harmony between two elements. Man, according to Confucian world-view, should respect and not intrude this harmony.

Seoul was sited in traditional manner in relation to the landscape.Today, river is no longer an edge;mountain ridges are main landmarks and borders for city and neighborhoods.

But harmony of settlement and nature had been lost as a result or fast urbanisation. Fleshfloods became a »natural« disaster due to failure of infrastructure.

Whole neighbourhoods are replaced with new structures which contrast drastically with previous condtion; infrastructure to remain for much longer.

Strategy 15/25

long-term structures

land-use

zoning

projects

Yongsan station—initial

Yongsan station—implemented strategic project

Waterfront—is it reasonable?

Yongsan market—structural element?

Yongsan market—strategic project.

How to invent lost harmony? Is ageing on the side of solution? How site and its qualities (density, transformation possibilities) can contribute? Which scale to address and which projects are strategic and which are not?

Strategy:long-term structures

16/25

long-term infrastructure current infrastructure current urban blocks urban blocks to preserve

The site is now facing major transformation. However infrastructure will remain for good. Strategy is to reatain some infrastructural qualities of urban fabric.

Strategies:land-use

17/25

~1sq.km

General land use strategy is to define the site of in-fill and minor transformation (A1), and site where major changes will take place (A2).

Strategy:zoning

18/25 mix-use commercial2

Monofunctional zones as a result of development trends are tied together with Âťmulti-functionalÂŤ infrastructure, or urban projects on intermediate scale.

Strategy:projects

19/25 Yongsan market as a future strategic project to enable ageing

Waterfront project, which is not yet implemented: aren’t the costs too high?

Yongsan station as a implemented strategic project with the goal to change »user« of the area; what are the consequences?

»Multifunctional infrastructure« is not new at all, however, the strategy is to guide this projects along the goals set for the site and its development.

Strategy:Yongsan station project

20/25

Market

Hangang street

Yongsan station is bridging Hangang street with the market, however, surrounding neighbourhoods developed in unplanned manner

Strategy:Yongsan station project

21/25

Market Market and station are symbiotically related: they share parking and traffic flow

Hangang street

Mall which now complements station caused the increase of land-value in the Hangang street viccinity,reulted in large-scale demolition and high-rise development.

Projects:waterfront:is it feasable?

Hangang riverfront park to be connected with developments at the former railyard; however, riverfront is accessible via bridges and main streets and activelly used.

22/25 In order to implement vison proposed by the mayor Oh, large scale demolition works are planned; but since new goverment of Seoul is elected and realestate market is not booming anymore in Seoul, why one should follow this strategy?

Next step of the strategy, initiated by mayor Oh was so called Hangang reinassance project, intended to further support land value of the territory. Isn’t the price too high?

Strategy:Yongsan market project Yongsan market is the identity of the area. However, its existence is endangered by internet shopping

warehoses of the market

23/25

this street is a covered river

Dense residential neighbourhoods have their green space on the traffic islands void of the former railyard

Yongsan market has specific condition caused by multiple factors, where infrastructure, density and human traffic plays major roles.

Strategy:Yongsan market project

24/25

New mono-functional development can benefit from services provided on the market Keep existing social networks, change vehicular traffic rather then user

Choice should be made to restore former river or to keep traffic

Pedestrian flow generated by the station has a special role in the project

The strategy is to reatin infrastructural system of Yongsan Market as a mediator, enabling slower change, keep weak ties: “keep vendor change customer�

Agenda for Design:Final statement

25/25

To enable qualitative growth, in other words, ageing (diversity, stability,...)

While city is constantly rebuilding itself, society and its infrastructure is ageing. Diversification or segregation, as a result of ageing, must be addressed spatially. It is that moment to develop attitudes towards ongoing trends. These also implies awareness of deteriorating impact of climate change, which regionally is very sensitive.

Framework for metamorphosis of the city in order to become more resilient faster on the one hand, and slower and more foresight on the other.

-How to prepare yong city for ageing?

-Harmony?

-How to fill the gap between small and large, fast and slow?

-Which scale every project should address?(Every project on intermediate scale) -How to slow down the development and how to define long-lasting features spatially and strategically?
