I like the idea of having the couch recessed under the window....in rear living area if we took out that wall we could do something like this with storage or books shelves or other built in features vs. taking the width of the while room.....allows for light, clears couch out of the middle of the room, etc.
maybe not our style but if living area is renovated in the back of the house, adding extra windows and/or skylight really improves lighting situation (which is currently very dark....)
