The concept of the architectural boundary has long served as a key point of investigation in architecture, mediating the relationship between buildings and the urban environment. This project reinterprets the building’s outer skin—not as a passive enclosure, but as an active interface that interacts visually and spatially with the city.
Located on a backstreet in Yangjae-dong, Seoul, the site is surrounded by a disordered urban fabric composed of small-scale developments, repetitive materials, and chaotic signage. To disrupt this monotony, the design strategically introduces contrasting layers within the building's boundary, creating a new architectural rhythm that dialogues with its surroundings.
Jointly developed by AXS Architects and LJL Architects, the project was commissioned by a defense company working in augmented reality and artificial intelligence. The renovation needed to reflect the client’s cutting-edge identity while addressing functional demands such as security. Given the project’s scope as a façade-only transformation, the challenge was to visually represent innovation and performance through architectural expression.
A lightweight metal panel system was overlaid atop the original dark stone façade. These optically responsive surfaces evoke themes of technological layering and speed. From afar, the panels’ shifting angles and calculated voids stir urban curiosity; up close, detailed perforations and shadows create optical illusions and spatial depth. As pedestrians move past, the façade responds—transforming the building into a living, reactive element of the streetscape.
