Studio Daniel Libeskind designed an iconic 46-floors sustainable office tower for the new Yongsan International Business district development in , South Korea. The design is inspired by YunDeung, traditional Korean paper lanterns. The aim was to create a faceted tower as a lantern, whose multiple planes reflect the sky and the earth while capturing the light on its differing angles. Therefore a glowing beacon for YIBD site is created.

The tower is sculptured and shaped by the urban context – it tapers at its base in order to create a feeling of space and openness for the pedestrian plaza. The floor plates and the views over Han River are maximized as the form reaches out in the middle of the tower, creating a sense of scale marking the gateway from the western entrance to the site. The tower tapers back and up to its top to allow the most light and air onto the other towers around, creating a strong ascending peak to the tower.

The tower form creates multiple perspectives, like a sculpture in the round, with an ever changing public profile responding specifically to the site. South and west facades of the tower contain unique vertical winter gardens which provide the direct access to natural ventilation and planted park settings at each office floor. The gardens are special amenities to all the tenants, while they also buffer to the direct sunlight hitting the glass building. They function as open, park space within the building and help to reduce the significant amount of heat gain, therefore the building could function more sustainably.

Harmony Tower is a state of the art workplace, interweaving themes of nature, sustainability, and efficiency in a faceted, sculptural form.
