The designers removed all the lightweight walls and stripped away the thick layers on the red brick walls, revealing its original texture, which provided a clear basis for optimizing the layout. The new materials, with their two distinct textures, were inspired by the gray washed stone and beige marble of the Old Library. Through elaborate segmentation and combination, the designers shaped new geometries and spaces that conveyed both a sense of history and strength, where the red brick walls and new partitions were hidden. Throughout the space, the presence of traditional doors is barely felt. All the openings are “naturally” formed by the different geometries, creating a harmonious flow. The upper parts on the walls are painted white, creating a material separation that visually enhances the sense of support beneath. Their unified height subtly suggests a library-like sense of order. NA-DECO, with its meticulous approach, has transformed the dilapidated old apartment into a humble and bright scholar's residence. It gently whispers of the vibrant undergraduate years at Tsinghua University, while nurturing the promising future of its owners.
