This work is a small laboratory for architecture and interior design. The existing building was an industrial structure with long-span trusses that severely separated all upper floor spaces. Therefore, the design requires innovative solutions that span scattered areas, break through the traditional industrial structure, and achieve functional freedom and spatial freedom. The design strategy and overall outcome embody the art of balancing historic preservation with innovative transformation of modern needs. The design carefully preserves the original structure and highly respects the aesthetics of the traditional historic space, while providing new experiences for creating spatial diversity and functionality.
