Inspired by glowing lanterns, Shanghai-based Neri&Hu has transformed an existing five-story building by Seoul-based architecture and planning firm IROJE into the flagship store for Korean skincare brand Sulwhasoo. Located in the fashionable Gangnam District, the project is characterized by brass lattice-­work that extends from the interior—where it shapes and envelops the different programmatic zones—to the facades and roof terrace. Inside, mirrored volumes reflect the golden grid, creating the feeling of an infinite structure throughout the retail area, spa, and offices. Beige terrazzo, gray brick, and wide timber floorboards add warmth to the space, which is illuminated by custom light fixtures installed amid the metallic framework.
