Tom Wiscombe’s (Emergent Architecture) design for the Cheongna City Tower is based on creating an innovative spatial, structural, and energy production device which will become an operational symbol of the future for the IFEZ Cheongna region. Located at the intersection of the main pedestrian passageway from east to west and the main artificial waterway from north to south in Lake Park, the Tower is intended to be a hub of urban activity and a new destination for the region. It is 400 M. tall and offers views of the ocean, the Incheon Airport to the west and Mt. Geyang to the east. The lower levels of the Tower contain various leisure and cultural activities such as art and design exhibition spaces, an assembly and lecture space, gift shops, and bars. The mid-levels of the Tower contain public Sky-Terraces every 50 M. as well as a Business Spine which contains showroom office space for various technology companies and cultural institutions. The upper levels of the Tower contain an astronomical observatory, a seasonal high-end restaurant with star chefs, and various lookout points and observation decks.
The structure of the Tower is based on a steel exoskeleton rather than a traditional structural core model. Three main structural spines weave along the facades, varying in terms of depth, width, and rotation in response to vertical and lateral forces as well as geometrical rules set by the design team. Similar to the inside of a turtle’s shell, these spines are merged together to form a hybrid of monocoque and frame-and-skin construction types.
