Do you have a closer shot of the brick area,including mantel?

I like the current brick, ceiling and trim, but if you want something less rustic in tone, I can see why you'd want to paint, or preferably lightly whitewash. The TV is good there, although we can't see to the left of the fireplace in the shot. I would not put it above the FP. That long plaid valance would come out quickly, if this was my home.

Is this your home and is it year round? What is your style? Do you have photos of room that you like, so we can get an idea? I personally don't care for the chairs, the table between them and the sofa, but that is just my taste.

To me, the brick wall and the wood ceiling and trim are what make the room cozy and beautiful. I wouldn't change them.

It would be helpful to know what look you are going for and what you like and dislike. Do you want light and airy or do you like the earthy tones?

It is a lovely space! Anything you do will look great.

I wouldn't initially make any changes to the wood and brick finishes themselves and would only change the furniture and other decor based on the desired design style.

A possible future home so think of that picture as a clean slate. Nothing stays.

The fireplace is centered on the wall. This room would function as a family room. Here is a picture from the opposite corner of the room.

Ultimate style is TBD but would need to modernize regardless. The space lends itself to a "rustic, comfy" feel.

I would leave the brick and wood alone. It makes the room cozy and unique and I don't think it's weighing the space down. Introduce lighter furniture, maybe a cowhide rug, a more modern fan or light fixture, and some living plants. You could put the TV on the wall with the tapestry and set up the seating area in an L-shape to face the TV and fireplace. Get a nice long dining table to really take advantage of that space and all the windows. It's a lovely room that appears to get generous light. I'm a bit envious.

No changes to the wood or brick. Is the TV staying there and do you have a third picture from the fireplace,beyond the chairs?

i think if the current owners had a rug delineating the dining room it would look better.

i'm thinking all of the stretch is along the left side, thats the way the oval can lights are going....

W/o knowing your or your style, kinda hard to say. If it were my home, I wouldn’t touch anything but I would put white slipcovers on chairs and sofa (or upholster) for an airy, country feel. The lovely furniture, as is, seems too formal/elegant for the almost rustic space.

Re: tv, I’d place above mantel but if this isn’t really a tv watching room, I’d leave as is.

Design elements of the structure are great. The room needs contrast!

Of the things you listed, I would leave it as is. FWIW, I even like the plaid valance, which probably conveys since the current owners won't be able to use it in their new home. Though if your goal is to modernize, you'll probably want to take it out.

The things I don't like about the room are all about the current owners' furnishings, and these comments I only offer up as "things not to do." I don't like how the chair upholstery pattern interacts with the brick (pattern is too similar in size); I think the size/shape of the rug is off and a square rug might work better in the living area. I think the dining table looks a bit undersized for the space, and would benefit from having a rug to define the dining area.

My impression is that there is a lot of excess floor area that is not being put to good use in the MLS pix. TV should definitely go where the sofa and tapestry are, IMO. How does the kitchen relate to the dining area? I would leave the brick and mantel until further down the road. While it is tempting to want to finish these jobs while the home is empty, you can end up with a mis-match of styles, colors and furnishings unless you have one start to finish plan. AND the finish on most makeovers is the paint, so don't rush into making these decisions at the wrong end of the process.

I think my main concern/top priority would be figuring out a way to wrestle the end table away from the current (former) owners. I think that's what I would be obsessing about right now. I think that end table is an amazing piece (the one between the 2 chairs).

It's a stunning space. I would not, personally, change anything, in terms of the architectural features/details.

I would bring in a more streamlined sofa and side chairs, probably in a lighter color. Whether light or dark - more streamlined.

Or reflective metal art... gold, silver, copper, etc.

Canvas.

I think I'd leave the tv where it is. But an additional option might be a tv lift cabinet - offers placement flexibility, etc.

I would give some thought to the wall color, which is not very attractive, and find a larger rug, and another for the table and chair area. As much as I like Oriental carpets they may not be the best choice. I don't think the variegated bricks are attractive and I would definitely paint or whitewash. The area may also look better without the mantel and that would make room for a great piece of art there. Two modern velvet couches in a great color facing each other, and chairs that differ from the couches in material, pattern and style placed where the chairs are now would give a cozier feel and provide more seating. A fantastic gallery wall over the couch against the wall would fill that space beautifully.
