making walls invissible

Is it possible to make a wall invissible?
I am trying to make an attic wich has four tilted roof sides. I can create four rooms with a tilted roof but this requires a lot of inner walls. What I would like is to keep the walls controlling the roof tilt but without the walls being visible....
Is this possible or is another solution more logical?
