The C1-20 building will be a significant urban anchor at the very center of the YIBD. It will have a strong relationship to the Retail Valley, to which it offers easy access. The building will mediate between Retail Valley and the surrounding office buildings and will demarcate the path from the Han River through the Retail Valley all the way to Yongsan Station.

The building provides a gross area of 58,400㎡ on 25 floors and at a height of 165 m. It is distinguished by a unique program mix that combines spaces for ‘learning, creating and communicating’. The building is comprised of educational institutions, a ‘synergy floor’ for events and exhibitions, a three-story fitness center, various regional headquarters for international companies, spaces for private clinics and a 3-star restaurant that opens up to the roof top terraces.

Its multi-faceted facade frame embraces the building’s aluminum-glass skin in a powerful, upward-spiraling motion. At night, the facade turns into a giant media wall displaying beautiful digital artwork. The appearance at night has a tremendous visual impact on the Retail Valley and will help give a strong sense of identity to the entire district. Thus, it will be an instantly identifiable Landmark for the entire district and a symbol for YIBD’s mission to reach out to the world.
