international architecture firm tange associates have sent us images of their development tower in the yongsan international business district (YIBD), seoul, korea. ‘YIBD block C1-20’ is a mixed-use building situated at the very center of the sector, mediating between the ‘retail valley’ and the surrounding office buildings. set as an urban anchor for the area, it will demarcate a path from the han river to yongsan station through its adjacent public spaces.

the structure has a gross area of 58 400 m2, stands 165 meters in height, with 25 floors that combine spaces for learning, creating and communicating. the building hosts a diverse program with educational institutions, a synergy floor for events and exhibitions, a three-storey fitness center, various regional headquarters for international companies, rooms for private clinics and a roof top restaurant with open terraces.

exterior facade

the architecture represents a metaphorical expression of the dynamic energy created by the retail valley and the building’s own distinct objective. the multi-faceted frame of the facade embraces the structure’s aluminum-glass skin that moves in an upward-spiraling motion.  during the evening, the exterior turns into a giant media wall displaying digital artwork creating a sense of identity to the entire district.

  • after seeing this i feel more attracted to a certain older building. check out “mesianaga kuala lumpur”

    charles says:
  • Tange has lost their japan tradition. I am not see any japanese character in this building which usually brought by other japanese architect such as ando, SANAA, ito, fujimoto, jun aoki & other. Even Riken Yamamoto\’s building in the other block still brought japanese spirit to their design.

    Maybe this may cause this \”new Tange\” not famous compared to \”old Tange\” (Kenzo Tange)

    ray says:
  • America needs beautiful, multi functional buildings such as this one. Am I going to have to move to South Korea to go see and hang out in beautiful architecture?

    Nicholaus says:
  • Apart from a lack of \”Japanese-ness\” that some people (perhaps validly) are bemoaning, this looks like a pretty convincing scheme programatically. I like it at street level, that\’s a very welcoming entrance, and there are some nice touches throughout. How cool is the spiral stair in the Fitness Centre! It\’s a clever floorplate and they handle the tricky geometry well.

    But I gotta return to the concept: it feels like they\’re having to squeeze alot into this, and it doesn\’t come off as elegantly as you\’d hope, the way those elements like the Event Floor Vantage platform pierces the wrapped external facade. Maybe that \”Japanese rigour\” should not have been neglected after all.

    The elements are there though, Tange will pull this off, they do good work.

    blau says:
  • @blau i agree blau, i dont say this project is bad, the building is very good performance, just less of spirit. For me or many architects in asia/east such as india (studio mumbai), indonesia (andra matin), china (wang shu), malaysia (kevin low) and also japan that have lots of culture and tradition, think that is better to brought local spirit as a concept and combine with contemporary idea, so the building have a unique character. Just opinion….V

    ray says:
  • Looks like \”Final Fantasy\” saga cause a great impact in this architect…
