GARDEN

Jamsil can change from an asphalt sheet into a Garden with grass and pine trees. It has a flexible programming of sports and amenities. It is a restoration of natural scenery, health oriented and adding greenery to public forest. The Garden is made of linear lines with pine trees that allow free views at eye level. The Garden makes lots of natural landscaped rooms for a wide array of most sports in the world. The Garden absorbs the stadiums and sports: quiet sports in the center and more noisy and hectic towards the Urban Loop. To protect the Garden and the facilities it has a visually open perimeter fence which welcomes visitors between sunrise and sunset. It has the characteristics of a hortus conclusus.

PLATEAU

The canal-riverfront is made of the long Plateau which has the potential of an urban beach. It is an ideal location (spacious and isolated) for adrenalin driven sports and stunts, the third category. We propose a morphology of dune shaped islands that create a varied and exciting landscape which will flood a limited time of the year. The islands will have specific programs on top, accessible by foot bridges, and other programs will be stretching along and around the islands on the Plateau. Along the river a series of piers extend from islands. The Urban Loop runs along and serves the complete length of the Plateau.
Along Tancheon waterfront a series of mixed use towers for startups and apartments are planned.

PROGRAMMING

The three zones allow three different categories of sports: natural sports in the Garden, urban sports along the Urban Loop and adrenalin sports along the Plateau. The sports are the basic program which is to mix with surrounding leisure and cultural and commercial activities and pavilions. Programs are small and atomized, behaving like plankton, which allows a flexible and balanced development. The mix will fit all people of all ages: children, men, women, elderly and disabled. Maintenance by non commercial communities, clubs and volunteers will make citizens involved, responsible and happy.
The exhibition-convention center is nested along the inside of the Hangang embankment. It has a linear foyer and a huge glass facade with views onto the garden.

STADIUM

The current logistics of the stadiums can be simplified. We propose to 1. demolish current decks and 2. instead build simple rings around the stadiums to facilitate the large flows of people and 3. to add business programs above and 4. truck&coach logistics below. The rings can be easily accessed from the urban Loop. Visitors of the stadiums will have opportunities to enjoy the wide variety sports, activities and amenities in the Urban Loop and the Plateau. The architecture of all stadiums is very muscular. We propose to apply a soothing strategy of deploying tensile mesh membranes as new skins. The membranes are at least 50% perforated to reduce wind pressure and allow natural ventilation. Facades behind the membranes are not representative anymore and can simply be maintained. The membranes will be artificially lighted from inside and projected upon. In this way the stadiums will be more emphatic through an ever changing appearance and will become broadcasting and advertising devices for the ten thousands of people around. In this way the stadiums will generate advertising revenues that can be invested in maintenance. To make the stadiums programmatically resilient we added volumes for business related programs on top of the rings. These added ring shaped volumes can be extended further.

URBAN LOOP

It all starts with the Urban Loop which is on top of the underground parking/ring road and on top of the embankment along Tancheon and Hangong waterfronts. Instead of being just an edge or perimeter of Jamsil, it has spine- and pedestrian boulevard-like qualities because it encloses the Garden with stadiums on one side and the Plateau with adrenalin-driven sports on the other side. The Urban Loop contains a mixture of urban types of sports, pavilions for commercial and cultural amenities and accommodation to stay. It is an interface with sideways entries to the underground parking, the Forest, the Stadiums and to the adrenalin sports, COEX and districts. Half the Loop is at grade and the other half is on top of the embankment. The embankment itself, which offers great views, takes the mixed programs on top. A series of tall structures on the embankment along Hanhang River offers adrenalin sports at high altitude, like a big wheel, para gliding, base jumping, parachute jumping, bungee jumping and freestyle climbing. The Urban Loop will function 24/7 and is also meant for citizens of surrounding districts.

INFRASTRUCTURE

The project optimizes infrastructure, parking and public transport. At grade it allows free access of pedestrians and cyclists. Visitor vehicle traffic has access to the parking below the Urban Loop via the entry-exit lanes of the current road system.
Coaches, busses and trucks are kept at grade and have access from Olympic-ro in the south and Baekjegobun-ro in the east to all stadiums via two specific service roads along the Loop that lead to circular one-lane parkings around all stadiums.
Maintenance and security vehicles, like police, fire brigade and ambulance can access the Garden. Fly over’s that connect the Bongeun Bridge with the undergrounded Olympic Road (section D) will keep the top of the Embankment Loop free of vehicles.
