The Daan Complex is located at the corner of Xinsheng South Road, Section 1, in Taipei's Daan District, bounded on the west by the major thoroughfare of Xinsheng South Road and on the south by a lane five meters wide. The idea behind the EHS Archilab + Hsuyuan Kuo design was to take curtains, which usually hang in interiors to block the sun, and move them outward to the exterior balconies to provide shade and rain cover. Instead of fabric, the external curtains are composed of silver-colored, perforated metal plates with a fluorocarbon coating. Floor-to-ceiling windows cover a large area of the building facade that lies just inside; this double-layer façade solves the problem of exposure to strong sunlight from the west. It also brings an integrated look to the outer skin of this residential building, with four households per floor and a total of forty households on twelve floors, creating a unified visual expression that faces the urban environment.
The perforated aluminum plates come in "S" shapes with three different radii of curvature. These simulate the rippling folds of curtain gauze, hinting at the positions of the openings and balconies inside and providing the legally-mandated space for emergency evacuation. The space between this outer skin and the floor-to-ceiling windows forms the building's "cortical membrane," which is expressed also in the ambiguity between our visual and our bodily sense of interior and exterior. The solid folds of this metallic facade glisten in white or gold with the passing sunlight. As light shines through transparent glass windows, shadows are cast on the walls and floors inside by the perforations in the metal folds, the passage of time thus leaving traces that mark the moments of our lives.
