My thoughts for your keeping room. Loveseats make for difficult arranging and generally people aren't comfortable turning toward each other to converse on a loveseat. I'd suggest an apartment sized chaise sectional in the flex style where the chaise can be reversed from left to right to make for easy arranging and rearranging when you want a change. A pair of arm chairs and an accent chair will give you seating for six. I just realized I put in a slider instead of your windows, but just a minor detail. Replace the valence and blinds with updated roman shades under stationary panels on the ends just covering the window frames. Can't see how high your ceilings are to advise where exactly to hang them. I added one floor lamp since I didn't see any task or accent lighting. Could you use a nice hanging light fixture or chandelier? Perhaps you have and need a ceiling fan there. Please style your shelves with 1/3 books, 1/3 decor items and 1/3 open space. The clutterd look of all the little frames is not working. I didn't show a picture over your FP but you could do that or use a mirror there if you don't plan to move the TV above the mantel. I think it would be hard on the neck since the room is so small. I have another thought in mind if you want to put the TV on one of the walls, so let me know what you think.

Any update on the keeping room?

I love your ideas, I just ordered carpet for my living room and the Keeping room is my next project. I measured the wall you recommended for the couch and I can't find a couch that will fit. It's 84", from the front of the fireplace hearth. I have been looking for a sofa styled chaise or something that give us a good view of the TV. If we put the sofa you suggested in front of the window, which i have found some that would work, seating in front of the TV would be limited. My long term plan is the redo the kitchen and remove the knee wall and put in a large island. One project at the time. I am sorry for not replying earlier. Thank you again for your input any other ideas would be appreciated.
