An easy way to use contrasting materials to define space is to create an accent wall. Use metallic panels from floor to ceiling behind your dining set or buffet to visually distinguish the dining area.
You can even visually separate open floor plans in large finished basements with opposing materials. Create a pub feel over a basement bar with metal ceiling panels and finish the rest of the space off with crisp acoustical panels.
Design a sophisticated feel in one section with white coffered ceiling panels for the adult side and simple charm with smooth, white tiles or drywall in the children’s play area.
