“We wanted it to look as if the building had exploded, and the colors can all be found in the surroundings.” “We looked at the colors of the city, which are pale-from white and gray to beige-and tested different types of stone against real skyline and color combinations and to ensure the density of veining would be appropriate,” says van Duijn. Each 3D-printed steel node in the facade is unique to maintain an irregular volumetric expression, and integrate the facade and primary structure into one element.Īlthough the design of the mosaic was developed using Rhino modeling, van Duijn says that first his team and their client stood on the rooftop overlooking nearby Suwon Gwanggyo Lake Park and examined a selection of different granite blocks from around the world to ensure their tones would evoke the feeling of the architecture that had existed since the city was first built. Particular attention was paid to making the loop feel light and transparent with a seamless connection to the building. These serve to establish a relationship between each escalator and floor, so that the building is easy to navigate.

“It also offers a different way of relating traditional retail with the outside and injects a different energy on every floor.”Ī central core of escalators runs through the structure, oriented around a series of voids. When it and retail floors come together, something very interesting-a new possibility-comes about without compromising each other,” van Duijn explains. “Almost half of the building is sunken, so it is almost like an iceberg. In addition to retail, there is a VIP lounge, a cultural center (which offers cooking and art classes), and several YouTube studios on the highest floor. The building comprises 18 floors total: Twelve above ground, six below, inclusive of five levels of parking. Inside, retail is stratified along traditional lines on different floors.

In places, the loop forms part of the 1.6 million square-foot building elsewhere it extrudes as cantilevered space that can be used for pop-ups and events. A geometric glass-and-steel walkway rises from the sidewalk around the entire edifice and up to a rooftop park. Those pieces, which use 14 different types of granite, lend the exterior an organic, textural quality that alternates between smoothness and roughness. OMA’s solution was to clad a simple square concrete-and-steel structure in a spectacular mosaic facade of 138,000 pieces.

Now a new luxury department store building designed by OMA has disrupted that monotony, looking like a meteor that has fallen to earth. Gwanggyo, a new South Korean city about an hour’s drive from Seoul, is a satellite for relatively well-off young families who work in the capital, but until recently most of its streets were lined with tall, bland commercial and residential units. While new towns are indisputably more efficient than older ones, they often lack the character that emanates from cities that have had decades, if not centuries, to develop their patina. Galleria, a luxury department store in Gwanggyo, features distinctive architecture by OMA.
