Located on leafy Schüttelstrasse, which runs parallel to the Danube Canal in Vienna’s second district, is the studio of Chinese-born artist Ma Jia. Marked only by the word “Eingang” (entrance) and situated on the ground floor of a 19th-century residential building, the studio’s unassuming exterior offers an ideal foil to the elegant surrounding Gründerzeit architecture. Step across the threshold, however, and visitors are greeted by a bricolage of rusted metal parts, hand tools, sketches, canvases, metal bars, ladders, and 3D art models, providing tantalizing clues into the nature of the work being created—and all just beyond the notice of the building’s many residents, who go about their daily lives largely unaware of this vibrant artistic world in situ.
