Project Signal reinterprets wayfinding as a sensory journey. Using "objects" as the architectural unit across Changhua Station and the Changhua Roundhouse, the design integrates identity and materiality into space. Inside the station, a 46-meter suspended light ribbon and streamlined counters redefine passenger orientation while reducing visual noise. At the roundhouse, weathering steel installations delineate tour routes, responding to the active heritage site through raw materiality.
