Harmony Tower

Seoul, South Korea


The Harmony Tower design concept is for a 46-floor sustainable office high-rise in the Yongsan International Business District (YIBD) development, a project with a masterplan by Studio Libeskind.

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. Three-story 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 sky gardens are thematically staged around four themes: Green Gallery, Meadow Plaza, Sky Savannah, and Urban Forest. The program of the gardens is varied, with some offering cozy, intimate environments, and others spacious, transparent spaces. 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.

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. The Harmony Tower is the smallest tower in the YIBD’s Sky Archipelago neighborhood and is adjacent to Renzo Piano Building Workshop’s 620-meter-tall Triple One tower; Dominique Peraud’s 300-meter tall The Blade; and SOM’s 343-meter high Diagonal Tower.
