Interior Space and Exhibition Design Chinese Brush Flow Residential by COSMOS D&M COG, LTD Chinese Brush Flow is a residential interior design created for a home shared by three generations in New Taipei City, Taiwan. Planning began at the roughcast stage, which allowed a clear separation between public and private areas. Natural stone materials such as marble, granite and ruby stone are used on floors, walls and cabinet backboards. Rose gold titanium-plated metal lines and a curved ceiling soften sharp angles and reflect indirect light. Dark marble tops on coffee tables, dining tables and bar counters resist staining and simplify daily care.
