This study explores late Joseon architectural technology through the "cultural biography" of wood, focusing on the 1834 reconstruction of Daejojeon (大造殿) Hall in Changdeokgung (昌德宮) Palace. By tracing timber's journey from forest to palace, it illuminates complex socio-technical networks involving central administration, forestry policies (Songjeong, 松政), and naval logistics (Suyeong, 水營). Crucially, the study analyzes how the ecological constraints of the main beam (daedeulbo, 大樑) functioned as active "material resistance." The inability to procure ideal timber was not a procurement failure, but a catalyst that forcefully expanded the state's logistical network to the Tongjeyong (統制營, Naval Headquarters) in the south. The material ultimately imposed its own physical conditions, actively reconfiguring the royal architecture's scale from 45 to 36 bays. Finally, this research highlights the discrepancy between this physical reality and its idealized depiction in the Uigwe (儀軌, Royal Protocols). Rather than merely documenting dimensions, the Uigwe recorded the successful mobilization of a nationwide network condensed within the daedeulbo. Thus, the "life of wood" demonstrates how a natural entity acted as an active agent in reshaping royal space, transforming an architectural member into a symbolic monument.
