Industrial interior design is popular for decorating lofts and old buildings, turning them into living areas, although it can also be used for traditional apartments and homes. What you need for this style is to create an illusion of rough surfaces and materials that indicate an industrial past. The simplest way to do this is to leave some walls or surfaces unfinished. In addition to some raw metallic elements that will create an industrial atmosphere, choose old industrial objects made of steel, metal or wood.
