international architecture practice BIG has developed ‘cross # towers’, a 21 000 m2 proposal positioned next to the existing urban fabric of the future development zones of the yongsan master plan, designed by studio liebeskind for the korean development group dreamhub. the design includes two elegant towers with a height of 214 and 204m. to meet the vertical requirements of the site, the exceeding building mass is transformed into an upper and lower horizontal bar, which bridge the two structures at 140m and 70 m elevation. the two edifices are additionally connected through the arrival areas at the ground level and a courtyard below ground.

‘the cross # towers constitute a three-dimensional urban community of interlocking horizontal and vertical towers. three public bridges connect two slender towers at different levels – underground, at the street and in the sky. catering to the demands and desires of different residents, age groups and cultures the bridges are landscaped and equipped for a variety of activities traditionally restricted to the ground. the resultant volume forms a distinct figure on the new skyline of seoul – a “#” that serves as a gateway to the new yongsan business district signaling a radical departure from the crude repetition of disconnected towers towards a new urban community that populates the three-dimensional space of the city.’  – bjarke ingels, founding partner, BIG

view from street level

both the upper and lower bridge introduce rooftop sky gardens accessible to residents, allowing for outdoor activities, while a courtyard at the heart of the development is an integral part of the overall architectural design. dramatic views towards the neighboring towers and visual connections across the space from the retail zone creates an exciting area for the inhabitants and visitors. the exterior landscape draws from the traditional terraces which blend together with the modernity of the design. pedestrians at the arrival deck connects the towers at ground level can enjoy impressive views of the links above and the submerged plaza below.

the development will offer over 600 high-end residences and amenities, including a library, gallery space and a kindergarten. the design ensures that the tower apartments have optimal conditions of the sun and landscape. the bar units are given value through their spectacular views and direct access to the roofscapes, activating the outdoor space. the exterior facades are developed to correspond to the different orientations and solar conditions.

  • Bjark’s going back to the OMA days with this one.

    bill parks says:
  • another embarrassment to be outlived…One wonders if there is such a thing as a muzzle for “architects”

    dchasemartin says:
  • Do I see THE CLOUD in the background of the renderings?? Is this project a “BIG bandaid” for that monstrosity? To be honest, this design resembles the cloud…..two square towers, just connected with 2 straight bridges.
    These developers are digging the same hole with this building.

    Less is More says:
  • I see this structure actually adding to the architectural language of the site. BIG is creating new dimensions in the urban landscape by extruding and suspending platforms. It is nice to see a different interpretation on the traditional skyscraper tower.

    Shawn Carter says:
  • i think it looks quite nice, especially from the street level. I like how it is a very different building but fits well with the surrounding.

    morteza says:
  • thumbs up here

    maybe this is what the cloud should have been

    dbkii says:
  • Oh yes a bit like that ( but with flashy renders

    Leo says:
  • This is far better IMO.. if you realise, BIG always interprets his design into a simple icon. and i love how it really resembles #

    NK says:
  • International business center competition Yerevan?!?
