Generally traced to 1960s–70s SoHo, New York, where artists converted disused factory and warehouse buildings into cheap live-work space, industrial style starts from what a building already has — brick, concrete, structural steel — kept exposed rather than covered with new finishes.
Exposed brick walls, unfinished concrete floors, and black-painted steel shelving or pipework are the core elements. Lighting usually comes from Edison bulbs with a visible filament hung as pendants, their warm color offsetting how cold the hard materials would otherwise feel. Materials that look better as they age, like leather, suit the style well.
Brick, concrete and metal alone can read as harsh and cold, so pairing in at least one or two warm textures — leather, wood — and keeping lighting at a low color temperature is a common way to balance it in practice.
When to use
Use it when a space already has brick or concrete worth keeping visible. Cold materials alone read as harsh — pair them with a warm texture like leather or wood.
