Don't know if anyone is stil interested in this, but we're putting up Estiluz A1153 wall sconces which take 200 watt halogen bulbs. We'll have 2 fixtures on each of 2 long walls. They've been recommended by our lighting designer to use to light up a large living room which is also open to a lrge foyer area, and open to the dining room. Those areas have their own light, but we're hoping some light will also spill in there. This is a co-op in a large NYC apartment building and we're not allowed to add overhead lighting wilred into the ceiling, which would have been our preference. The many floor lamps we've been using have been ineffective and unpleasant to use;. It's a large are and we want to be able to hit a switch and light up the room. Instead we have to walk around turning on at least 4 lamps in various corneres, and the light still isn't satifying. If anyone is interested, I'll let you know how it works out.

Your sketch (or your builder's) has three separate, individual and unrelated elements: the walls, the fireplace and the casework for the TV. Nothing dominates--everything competes visually. Dominance is one principle for good design. Cpartist's sketch is much more unified: fireplace and casework are unified together and dominate the wall, leaving only a small portion of the wall visible. For increased dominance and unity, you might consider some type of fascia or crown molding which is in keeping with your house architecture. You could align it and run it full-width, across the top of the door and all casework. An option for the heavy-appearing masonry above the mantle would be to use wood paneling, finished to match your casework. In choosing your design and finishes don't forget to coordinate the door and frame to the left, if there is one. As for the TV, I'm not sure how far away the kitchen actually is from the TV location, but even if you can adequately see the video, I'm not sure you will be able to hear the audio, unless you have wired speakers in the kitchen. What are the chances of a well located and designed TV in the kitchen--perhaps a flip down flat screen under an upper cabinet? Good luck with your project.

Please do more research about putting a TV above a FP. Here are a few threads & ideabooks to get you started in thinking about the best location for your TV without it taking over your space: https://www.houzz.com/discussions/on-my-soapbox-mounting-the-flatscreen-too-high-dsvw-vd~4537748 https://www.houzz.com/magazine/where-to-put-the-tv-when-the-wall-wont-work-stsetivw-vs~595002 https://www.houzz.com/magazine/design-dilemma-where-to-put-the-flat-screen-tv-stsetivw-vs~185304

Is that a functioning fireplace? It appears to just have candles inside of it? If it is not a functioning fireplace, then mounting a TV above it, may not be bad if you can remove that mantle and mount TV a little lower. That's a small room to watch a TV mounted high on a wall. PLace TV above the shelf wooden cube shelf & have sofa float/face it. You can move sofa now & take pics to see if it seems too cramped. Or but a corner TV stand with a wall mounted TV you can pull out & angle when TV is being used. Or buy a smaller flat screen and mount on 32" wall & down the line, have built in made cooperating fireplace. If this is not the only TV viewing room, I would consider not using it for main TV viewing.
