Hello! I need ideas for what can be done above the wall seen in the picture. That is the first thing seen whenever someone enters the house and it will have TV on the right side and a floor lamp on the left side. The gap between will be covered with a white grainy door. The above part should be covered so that the Air Conditioner cooling won't escape from Living Room to the Kitchen. Kindly suggest on what can be done. Any idea is appreciated.
