An interior designer's fantasy uses a media wall as the focal point of your room which is the current trend. A fake chimney is simple as it conceals wires of a TV and an electric fireplace that would be visible and unsightly. Since there are no TV stands or other obstructions surrounding your TV and fireplace, it appears to have more space even if it occupies more space than the original wall. You can mount the TV and fireplace to any wall using a fake wall without endangering the structural integrity of a load-bearing wall in your house.
