14 1/2 Street
Here is the bonus room I mentioned with the row of "window" seats that also operate as twin beds / lounging. I think something like this in your playroom would be a great use of space. Think of the epic sleepovers! And could provide toy, game, etc. storage. I also like the ceiling with the beam across the cathedral. Something like this would be an interesting detail in the room.
The more I see some of these walls, the more I'm thinking if you do something dramatic or different with the serving area behind the dining table, it would help to segregate the areas.
