The rooms in the house will be easily removable and replacable so if you want a spa room or a video game room the builders would change the rooms that you don't want.
Earphones will be provided to you and the house will know what kind of music you want. Also if someone was talking to you the sound would become lower automaticaly. The walls will be screens and usable by everyone. For example, if I am watching "Haters Back Off" but unfortunately I need to go to the bathroom, the image would follow me and the sound would still be in my earphones.
