Transit Oriented City in Dongtan, South Korea by Ojanen Chiou Architects

Article source: Ojanen Chiou Architects

Designed by SWA Group with Ojanen Chiou Architects LLP, the 157 hectare Dongtan Central Business Master Plan is at the heart of Dongtan City: a new urban center located just 30 km south of Seoul in South Korea.  The development zone is situated on a former agricultural plain that had been taken over by various industrial uses.  Bounded by a river to the west and mountainous terrain to the east, this zone is bisected by a major transportation corridor connecting Seoul with the southern reaches of the country.  At the core of the development is a transit center that will accommodate high-speed and metropolitan rail stations connecting with a bi-modal (bus + tram) transit system, and long-distance and city buses, establishing Dongtan City as a major regional transit hub.

Transit Oriented City

The remainder of the program includes public plazas, office buildings, a corporate campus, retail functions, hotels, schools, and various cultural facilities.  Inspired by the local native ecology, the layout is a constructed response to the natural course of water as it moves from higher to lower elevations.  The urban fabric is organized by a series of green zones established around a system of watercourses traversing the site, infusing the overall urban experience with a strong sense of nature by creating natural corridors of light, air, flora, and fauna, and providing numerous open spaces for leisure and recreation.



  • Define open spaces that utilize natural resources prior to establishing street grids:  Create fingers of green belts that connect hills on the east side and the riverfront on the west.  The landscape infrastructure follows the unique site topography and hydrology and becomes part of an integral water management system.
  • Establish public transportation node: Provide well-integrated system of trains, metro, trams and buses to attract corporations, residents, commuters, and tourists.
  • Propose compact and mixed-use developments:  Balance high density development (FAR 5-8) with 36.5% open spaces that are dispersed through out the site and easily accessible.
  • Promote pedestrian and bicycle network with pedestrian-scaled blocks, comfortable sidewalks, continuous street facades with arcades and three-dimensional connections at busy intersections.

Site Location
