Interior Space and Exhibition Design Optical Fibers Residence by Yu-Wen Wang Optical Fibers is a residential interior design completed in Taiwan. Light and shadow guide the whole layout. The living room, study and dining room are connected without partitions, which keeps the space bright and open. An L shaped sofa and a writing desk divide the living room from the study without a solid wall. The television wall is built with stone, metal and wood, and grey tones are combined with titanium plated metal. Wooden cabinets add warmth. In the bedroom, an inclined ceiling with strip lights hides the low beams and columns.
