Dining rooms
I like how the wall gives you makes it incorporated into the other rooms, but at the same time it separates it from the rest. A problem we always had was that the adults always wanted to talk, but the kids wanted to play. We'd increase our volume until we'd be screaming over each other. This makes it so much better.
I think the wall would make a great accent wall, but would be too much for the whole house.
