..is there a possibility to look at this ledge as if it was a useful surface rather than strange impediment? for example is it possible to hang your TV over it..not too high..and use it as a surface for TV things/videos/books beneath?

that way you have your improvised console already built in the space. you don't add another furniture but use what's there

of course you know the plan of your room better..technically can it be something that'll work?

I rather like the fireplace itself..like your new sofa...but I need to understand first the TV situation ..layout will inform the decor..or so I think

What a fantastic space you have. Great windows and your fireplace is such a cool unique feature. I think the idea of using your fireplace ledge for you TV is genius. Every seat in the place could view the TV better if it was there also. Do you like that idea? But you MUST be able to hide your cords!

You would then have the space available where the other TV stand was for an end table and another lamp. Not quite sure of your style so I'm fishing.

Simple drapes to match the ones in your reading room which, by the way, looks really nice. The rug and sofa couldn't be more perfect together. I'd say move your floor lamp closer to the sofa so you could actually read......add a couple larger plants. Tree size.
