How do you dress a long, skinny living room? The same way you dress a tall, skinny woman! Put a belt on!
In this case, the belt is actually going to be the couch that intersects the room with a sofa table behind it, thus creating a formal entry and an intimate conversation area.
In Seattle we have a lot of Tudors and bungalows with this floor plan and this is the best staging solution that I've been able to come up with.
