University of Hong Kong professors John Lin, Olivier Ottevaere and Lidia Ratoi worked with students to overhaul a yaodong — a traditional underground dwelling carved into the loess cliffs of northern China — combining hand-laid brick vaults with 3D-printed components to reimagine a building type that has existed for millennia. The project challenges the assumption that “the future” means building new, finding innovation instead inside an architecture defined by its relationship to the earth around it. Source: Dezeen
