due to noise disturbance: We have a bungalow, meaning the kids hang out right by the living room. We built very open, but still installed a door to the hallway. That is necessary because when my husband watches (he has hearing difficulties), it gets loud. I can hardly hear it in the bedroom with the door closed. So two doors in between. As soon as there is another floor in between, it gets even better. Feel free to plan a door to the hallway with a large glass window, and you'll get enough light in. If the hallway is made a bit rounder by, for example, a corner staircase, that is completely sufficient. When my son is sitting at the top of the stairs at my parents' and calls down to us, we quickly miss it during a normal conversation. No wall and door can withstand massive metal music provocation from teenagers.
