Wangou Art Avenue regenerates a former armament factory on Longquan’s west edge, fusing natural landscapes with industrial heritage. A renovation-first “textural memory + spatial interweaving” approach preserves original factory scale and structure, while nested volumes, walkways, and permeable courtyards knit isolated buildings into a continuous public interface. Grey zones between old and new spur civic and creative life. A clustered, multi-layered layout integrates art center, museum, convention venue, studios, retail, and waterfront spaces into a sustainable, vibrant cultural ecosystem.
