A 46-floor sustainable office high-rise, The Harmony Tower was designed as a glowing gateway to the western entrance to the Yongsan International Business District (YIBD) in Seoul. Inspired by traditional Korean paper lanterns, the design concept considers the tower a faceted lantern with multiple planes that reflect the sky and earth and capture light from its differing angles.
In subtle ways, the tower serves its urban context, tapering at its base to create a feeling of space for a pedestrian plaza, expanding in its middle to maximize floor plates and Han River views, and tapering again at the top to allow maximum light and air onto neighboring towers.
Vertical winter gardens on the south and west façades provide users with access to natural ventilation and planted gardens at each of the 38 office floors. The gardens not only act as open, park space within the building for the tenants, but also as a buffer to reduce heat gain and allow the building to function more sustainably.
