Is the living room at the back okay?

Of course it would be better if the living room is at the back.

Because the atmosphere of our usual family is that the bedroom and living room are placed together, and it is the same no matter who goes to bed before or after.

The most important thing is that our living room must not be next to the toilet, because this will affect our daily rest indoors, and our living room must use dim lighting, which can cause A cinematic feel.
