From 7 p.m. to 9 p.m., visitors crowd inside an early 20th century hanok near the southern entrance of Gyedong-gil. Around half are tourists. Everyone looks content, sitting with artisanal coffee and baked goods inside the grand wooden structure. One section is entirely cleared of the foundation, flooring and walls to create the open chamber-like space better suited for a factory. Glass slabs are fitted into wooden frames and cement is poured into recesses to finish off that hipster vibe customers crave.
