Swiss-Italian practice Stocker Lee Architetti has completed a monolithic retail space in Seoul’s Itaewon district, featuring a textured concrete shell and a translucent glass-block facade that glows after dark. Designed as the new Manmade Flagship Store for South Korean fashion label Wooyoungmi, the building is a direct response to its constrained urban site. Located on a sloping, curved plot, the structure’s geometry is derived from its perimeter, creating a volume that mirrors the sweep of the adjacent street.

The Wooyoungmi flagship store is defined by a rigorous approach to materiality. The architects chose to wrap the building in exposed concrete cast against OSB (oriented strand board) formwork. This process leaves a rugged, organic imprint on the surface, treated with a mineral glaze to emphasize a patina that resembles the weave of a heavy textile.

“The architecture provides a subtle backdrop for the sartorial collections,” explained the studio. “The structure and character transform with use, much like an interwoven fabric.”

A screen of glass blocks defines the primary facade, acting as a filter between the boutique and the bustling city. During the day, the interior is washed in a soft, clinical light; by night, the building acts as a lantern, emitting a muted radiance onto the sidewalk. This play of architectural lighting is intended to move beyond aesthetics, aiming to trigger a visceral, emotional response through the manipulation of transparency and shadow.

Inside, the Seoul retail design navigates the site’s steep incline through a series of staggered mezzanine levels. These floors are connected by a central vertical core that serves as the building’s structural and navigational spine. This arrangement creates a “continuous spatial sequence,” where varying ceiling heights produce a rhythmic shift in atmosphere and scale as visitors move through the collection.

The interior palette remains strictly functional, utilizing steel, stone, and wood to complement the raw concrete. This minimalist architecture avoids decorative flourishes, ensuring the luxury fashion display remains the protagonist of the space. Each material was selected for its structural integrity and sobriety, aligning the architecture with the brand’s focus on craft and precision.

By integrating the building so closely with its urban context, Stocker Lee Architetti has created a landmark that feels permanent yet evolving. The Manmade Flagship Store in Seoul stands as a quiet departure from traditional high-street retail, offering a sensory environment where the weight of the stone and the lightness of the glass create a balanced stage for high fashion.
