Interiors firm Wonderwall trafficks in receding architecture and monochromatic walls. These minimalist tendencies have been the ideal foil for retail projects like Uniqlo’s New York flagship and A Bathing Ape’s global cache of outlets, as they bring quiet order to the riot of colors and patterns on offer. But Wonderwall broke out of its mold with its first project in Moscow, a store for British sporting wear company Fred Perry. The layout features a main area and sunken room, which is located a few steps down from a long hallway. Wonderwall principal Masamichi Katayama imaged that in an earlier life, the sunken room had been a secret salon where the young Soviet elite gathered. So he decorated it in a traditional Russian style, with brick walls, tufted leather sofas, and tapestries featuring regional designs from around the country. He contrasted these elements with white plaster expanses and modern materials like stainless steel, which appear throughout the rest of the space. But lest he forget his client, he also had the ceiling beams designed to form a Union Jack, as a nod to Fred Perry’s origins.
