Think how your furniture will work for a seating arrangement if you create 2 focal points. Is there a basement where you can have a huge tv?

I always like a tv over the FP. Just a neater look.

I wouldn’t do the wall to the right. If anything the left of the FP.

Again, I’d do tv over fp

I like how it was staged. can you move your sofa like that and bring in a rug and coffee table?

to me it appears crowded under that window.

as for the over the FP, you could always fill in the niche portion and make it a solid 'wall' above the fireplace, (similar to this picture)

you could also fill it in w/shiplap, shown here. do some built ins on the left.

what do you think about this staging? For the large wall, get a long console, some art,

Or, see about removing those white rails around the fireplace (or above the firebox) fill in the niche add a wood mantle, and try this:

and, you could do some shelving or a chest to the left. with the sofa there, it's covered.

a little bench on the left, a chandelier, wood mantle, tv. now move the sofa directly in front,

or do a move the sofa on the other side and put two chairs on the window side. kind of like these

Suggestion: what temp lights do you have? if they're 5000K, I'd tone them down to a 3500 or so. the higher the temp, the colder the light appears.

Can you move the sofa like the staging photo, snap another photo straight on, and I'll photo shop some ideas?

Beth- those are some great ideas, I didn’t think about filling the niche portion, that would give us more room for a bigger tv.

The shelving ideas you shared and photoshopped definitely look good too! Here are some additional pictures with the same couch in the position as the original staging.

I was also thinking a light fixture hanging in the middle of the living room, what do you think about that?

If you like the large wall idea, you'd wall mount and get a proportional media console

fill in the sides w/a chair or plant.

you need a large area rug and coffee table.

or, you could try something like this

Could you do the tv similar to this (but on the left side of course)

another modification idea you could do to the fireplace. fill in the niche and do some wood trim molding, hang tv. change out the surround to something like this white one (around the black)

give me a few minutes to photoshop some ideas

what do you think about something like this?

taller ceilings here, but you could do a lot of the decor ideas. I like the dark wood trim molding idea above the fireplace.

The rug, a wood table and some plants would look great.

Look at this next picture and how they did the area above the fireplace. you could keep your vertical white borders and just do the shiplap across the middle.

Right now the grays and whites are a bit cold looking. you need some warmer elements.

try an area rug, some warm wood consoles or table, and this warmer gray color on the walls.

I gave you a diff mantle surround (just photoshopped the picture) and did the shelves on the left and a chair. This textured rug would also help soften the cold look to the room.

Beaded chandelier.

here's another style

wood shelves, wood topped lower cabinet, wood mantle, shiplap

over on the long wall, what if you did something similar to this photo (look at the far wall on the back)

Ikea kallax hack if you like the bench idea

Do you like this type of light? What about the darker area where the tv goes?

you could do sofas like this, w/a few chairs at the 'top'

Looks like this straight on. This color is BM Cyberspace.

The before shot. similar to your wall, yes? the dark is gorgeous.

Dark peacock, lighter wood accents and woven rattan type of light. love the rug

I have a few more. next comment

part II,

Just trying to bring in some elements to warm up all that gray.

for the lights, don't know if you like gold, black, glam, farmhouse or more modern

Georgia and Lulu rug (they have lots of colors. or try CostPlus World market. cheaper)

Against the wall I gave you a walnut console, but you could also do something like this in a white, gray or black

If you prefer the TV over on the wall, it would look similar to this^ But you'd have to do a longer type of unit. I really like this one. this is too yellow for your gray theme, so it would need to be a diff color.

or, try a console like this, no tv (do art or a mirror) bring in plants and other elements like this pic

Those current counter stools you have are too dark and the wrong style. I gave you two in the first pic I photoshopped of your kitchen area.

I like the woven loom type of chair,

or, the backless one I stuck in the picture are like mine, shown here.

I have the similar white/gray and marble, but I brought in the warmer wood elements and color w/my art. I have the black leather sofa and bench, lighter rug, leather pouf, etc.

If you like the black accents, you could do your fireplace wall in black, or charcoal, or any other color.

You could also position the furniture shown here, along w/the rug^

Or, what about this one? has a more modern light, open shelving next to window, and a thicker, dark shiplap over the fireplace.

cooler tones that are similar to your house. notice the light. the chair and wood tables.

if you kept your sofa facing the fireplace, you could do side table, sofa table like shown, and a few chairs.

Beth- these are some amazing ideas. Thanks for taking the time to edit and posting these. My wife actually took my phone from me and started pointing out all the things she likes from the ideas you posted. We are thinking about possibly filling out the niche portion and putting a TV over the fireplace. And as you showed in some pictures, doing a counter/shelving on the left side. We also like the idea of painting the fireplace wall a darker color and are considering going that route. A nice light fixture will look pretty good we think and definitely getting some wood colors in there.
We both like the modern look and want to furnish this space the same.

This is a new house we just moved into so we brought over some of our older furniture until we can start getting new furniture.
