The New City Main Library project is the first stage of the “Regenerating Sangmu Incinerator” initiative. The library is located in Sangmu district, characterized by housing complexes, commercial establishments, and governmental offices. The project reimagines the incinerator site, preserving the factory, demolishing administrative and welfare structures, and relocating heat supply facilities. The proposal combines a public library with community sports amenities, aiming to establish a cultural landmark that redefines the library’s role and explores synergy between digital media and traditional resources for advancing culture.
