In response to the Seoul Metropolitan Government’s Yeoui-Naru Ferry Terminal Design Competition, PARTISANS evolved the Han Gang Wishbone, amphibious architecture that seamlessly connects water and land, leisure and tourism, people and culture. Inspired by a wishbone—the fused clavicular bone in birds that strengthens their thoracic skeletons and enables them to withstand the rigours of flight—the Wishbone is at once elegant and robust, tailored to respond to cultural, commercial, and climatic contexts.
The Ferry Terminal is the signature structure within a larger tourism and culture revitalization effort that prioritizes three additional projects: Yeouijong (shops and restaurants), Yeoui-Maru (a shopping centre), and the Ari Cultural Centre. The Wishbone integrates the four projects into one sweeping and fluid design move that addresses functionality, program, and climate. The rationale for integration stemmed from a consideration of the site, which is situated between two bridges (Mapo and Wonhyo) that connect the Yeouido district to the north part of the city. There is a parking lot and popular Yeouido Park to the west, and a subway station to the east. Citizens’ Park is a vast, mostly concrete space used by Koreans and tourists alike that extends toward the water.
The governing design factor for the terminal is flexibility in the face of fluctuating water levels. Thus, the bridge connects to the appropriate terminal floor no matter the water level, while the ferry terminal remains a self-supporting structure. The formed base legs are concrete and, in combination with the concrete cores for the elevators and stairs, provide a robust base on which the steel superstructure may be supported. Due to the dual cantilevered nature of the structure, high stresses are anticipated at the interface between the steel superstructure and the concrete base.
