paris-based dominique perrault architecture has developed ‘the blade’, a 300 meter high tower positioned within the future dream hub yongsan international business district. the structure establishes itself in as a geographical landmark. its silhouette and shape is not a square or round building but a rhomboid prism, arranged in a way to make it look dynamic depending on the angle of approach. it is slender in shape with sharp edges contrasting the urban landscape. the edifice is in a dialogue of light and reflections with the neighboring skyscrapers as its facade fragments and reconstructs the perspective like an optical instrument.
the skin of the tower is clad with glass, which allows the exterior to release luminous halos which envelop the outline of the structure. this vibration creates a sense that the architecture is living, transforming itself with the movements of the sun and the changes of light. the project sculpts the void space, offering views of the grand seoul landscape. the grand lobby, the business forum, the panorama lobby constitute as many cut-outs in the volume, which are dedicated to promenades and relaxation. this superposition of free areas contrasts with the constructed volume of adjacent skyscrapers and accentuates the lightness of the prism.
